Atmospheric  sciences  reports  that  list  computer  programs  and/or  their  documenta- 
tion are  cited.    These  software  applications  pertain  to  topics,  such  as  aeronomy, 
atmospheric  motion,  meteorological  data  processing  and  weather  forecasting,  me- 
teorological instruments,  physical  meteorology,  and  weather  modification.    The 
directory  contains  complete  bibliographic  data  for  each  report,  as  well  as  a  subject 
and  a  corporate  author  index. 

The  computer  software  offered  by  NTIS  was  created  by  a  variety  of  Federal  agen- 
cies to  meet  their  diverse  but  quite  specific  objectives.    It  is  provided  without  in- 
stallation, support,  or  maintenance  services  and  sometimes  requires  customer 
modifications  to  run  effectively  in  customer  environments.

INTRODUCTION 


The  National  Technical  Information  Service  (NTIS)  of  the  U.S.  Depart- 
ment of  Commerce  is  the  central  source  for  the  public  sale  and 
announcement  of  Government-sponsored  research,  development  and 
engineering  reports  and  analyses  prepared  by  Federal  agencies,  their 
contractors  or  grantees.  NTIS  supplies  the  public  with  approximately 
four  million  documents  and  microforms  annually. 

The  technical  reports  announced  by  NTIS  often  contain  listings  of  com- 
puter programs  and/or  documentation  covering  a  wide  variety  of  appli- 
cations. 

The  object  of  this  directory  is  to  announce  to  the  scientist,  systems  ana- 
lyst, and  programmer,  the  availability  of  these  computer  programs,  and 
to  disseminate  this  software  as  fully  as  possible  to  fulfill  NTIS'  role  in 
information  transfer. 

These  computer  program  listings  or  the  documentation  can  be  pur- 
chased for  the  regular  price  of  the  technical  report  in  either  hard  copy 
or  microfiche,  thereby  providing  the  user  with  a  viable  piece  of  soft- 
ware at  an  exceptionally  low  price. 

If  there  are  any  questions,  comments,  or  suggestions  please  contact 
David  Grooms,  Product  Manager   (703)  557-4672. 


The  computer  software  offered  by  NTIS  was  created  by  a 
variety  of  Federal  agencies  to  meet  their  diverse  but  quite 
specific  objectives.  It  is  provided  without  installation,  sup- 
port, or  maintenance  services  and  sometimes  requires 
customer  modifications  to  run  effectively  in  customer  en- 
vironments.

A  computer  program  and  associated

high  resolution  spectra  for  inhomogeneous  op- 
tical paths  including  both  atmospheric  condi- 
tions and  conditions  typical  of  a  missile  plume. 
These  programs  and  procedures  are  outlined  in 
this  report.  The  procedures  have  been  used 
with  the  Air  Force  Cambridge  Research  Labora- 
tories line  atlas  to  demonstrate  that  ignoring 
the  correlation  of  atmospheric  absorption  lines 
with  source  emission  lines  can  lead  to  errors  as 
high  as  79  percent  for  some  spectral  bands  and 
optical  paths.  Calculated  spectra  have  been 
compared  with  experimental  laboratory  spectra 
typical  of  both  atmospheric  and  missile  plume 
conditions.  The  AFCRL  line  atlas  requires  the 
addition  of  lines  from  highly  excited  states  and 
the  correction  of  certain  inadvertent  errors  to 
be  applicable  to  the  calculation  of  high  tem- 
perature optical  properties  of  gases.

A  computer  code  is  described  which  deter-

the  lower  atmosphere  by  the  bremsstrahlung 
emitted  from  an  incident  flux  of  auroral  elec- 
trons interacting  with  the  atmosphere.  The 
code  is  named  BREMGAT  (bremsstrahlung 
generation  and  transport  through  the  at- 
mosphere) and  consists  of  three  major  FOR- 
TRAN programs  called  AURORA,  FONTONQ, 
and  MCBREM.  The  programs  are  executed 
consecutively  in  the  order  given.  AURORA 
determines  the  flux  of  electrons  produced  in  a 
model  atmosphere  by  the  given  incident  spec-

In  order  to  ascertain  the  electron  density  in  the 
earth's  ionosphere  by  direct  measurement  a 
radio  frequency  (RF)  impedance  probe 
technique  has  proved  useful.  This  technique  in- 
volves monitoring  the  changes  in  impedance  of 
an  antenna  mounted  on  a  rocket  or  satellite 
vehicle  traversing  the  inospheric  regions  of  in- 
terest. The  changes  of  antenna  impedance  can 
be  related  to  the  electron  density  of  the  sur- 
rounding plasma  through  use  of  suitable 
theoretical  development  of  the  antenna-plasma 
interaction.  It  is  the  purpose  of  this  treatise  to 
develop  a  more  general  expression  for  the  im- 
pedance of  an  antenna  in  the  ionosphere  to  be 
useful  as  an  RF  probe  for  measurement  of  elec- 
tron density.  The  investigation  of  ionospheric 
plasma  characteristics  by  means  of  such  RF 
probes  has  received  a  great  deal  of  attention 
since  the  advent  of  the  rocket  allowed  direct 
measurements  within  the  ionosphere.

A  knowledge  of  the  natural  infrared  radiance

of  interest  for  systems  design,  military  surveil- 
lance and  the  advancement  of  knowledge

perimental data  on  and  theoretical  estimates  of 
excitation  processes  that  lead  to  emission  of  in- 
frared radiation  has  been  implemented  in  a 
computer  program  that  computes  infrared  radi- 
ances for  an  earth  limb  viewing  geometry.  The 
nominal  spectral  region  of  this  study  lies 
between  2.7  and  25  micrometers  and  emphasis 
is  placed  on  radiation  originating  at  altitudes 
between  70  and  500  km.  The  physical  model  is 
described,  with  emphasis  on  the  changes 
required  in  extending  its  usefulness.  Applica- 
tion of  the  computer  program  is  described  and 
estimates  are  given  of  uncertainties  in  results 
due  to  assumptions  made  in  the  model  and  lack

This  paper  compares  calculations  of  vertical 
and  surface  dosage  distributions,  obtained 
from  a  finite  difference  numerical  solution  of 
the  classical  line  source  diffusion  equation,  to 
calculations  obtained  from  an  analytical  solu- 
tion and  to  observed  distributions  obtained 
from  several  line  source  releases  The  analytical 
solution  uses  constant  values  of  vertical  turbu- 
lence and  wind  speed  averaged  with  height. 
This  solution  then  approximates  the  effects  on 
surface  dosages  of  increasing  stability  aloft  by 
using  reflection  from  the  top  of  the  mixing 
layer.  The  finite  difference  numerical  solutions 
considers  the  change  of  eddy  diffusivity  and 
wind  speed  with  height  in  such  a  way  as  to 
produce  vertical  dosage  profile  closer  to  the 
observed.  Turbulence  values  for  use  in  the  nu- 
merical model  are  obtained  from  calculations 
of  vertical  diffusivity  based  on  statistical  theory 
The  numerical  solution  predicts  the  vertical 
dosage  profile  more  accurately  than  the  analyti- 
cal solution.  Both  solutions  predict  surface 
dosages  equally  well.  Verification  of  the  numer- 
ical solution  on  other  data  appears  desirable.

Using  a  one  level,  barotropic  ocean  model, 
driven  by  surface  winds,  a  finite  difference  form 
of  the  vorticity  equation  was  integrated  over 
210  days  of  simulated  time.  The  solutions  using

were  compared  with  those  using  a  variable 
coefficients  derived  from  enstrophy  cascade 
and  energy  cascade  Using  a  constant  eddy 
viscosity  coefficient  of  rather  low  magnitude 
produces  a  large  amplitude  computational 
oscillation  which  fills  the  entire  basin.  An  order 
of  magnitude  larger  coefficient  produces  a 
marginally  satisfactory  solution,  where  the 
western  boundary  current  was  rather  well 
represented,  but  a  moderate  computational 
oscillation  was  still  evident.  By  increasing  the 
coefficient  yet  another  order  of  magnitude,  the 
computational  oscillation  is  negligible,  but  the 
solution  in  the  ocean  interior  is  unrealistically 
damped.  An  accurate  physical  and  numerical

western  boundary  with  no  computational  oscil-

Two  empirical  density  models  based  on  drag 
analyses  of  22  low-perigee  satellites  are 
developed  for  use  in  predicting  low-altitude 
satellite  ephemerides.  A  stepwise  multiple 
regression  analysis  is  performed  with  density  at 
145  km  as  the  dependent  variable,  and  a 
number  of  independent  variables  chosen  to 
represent  variations  with  solar  cycle,  geomag- 
netic activity,  latitude,  season,  day  of  the  year, 
and  time  of  day  Densities  between  120  and  500 
km  are  determined  from  the  hydrostatic  law  in  a 
simple  (but  physically  realistic)  analytic  form. 
The  two  models  compare  very  well  with  the 
1971  Jacchia  model.  The  main  advantage  of 
such  models  is  that  they  represent  a  major 
savings  in  both  computer  storage  and  run  time 
making  possible  improvements  in  operational 
systems

An  Atmospheric  Dispersion  and  Environmental 
Prediction  Technique  in  model  form  was 
developed  and  validated.  The  model  was 
developed  as  a  computerized  aid  to  enable 
rapid  objective  analysis  and  calculation  of  at- 
mospheric trajectories  and  streamlines  on  the 
mesoscale.  Several  observational  weighting 
techniques  were  investigated  to  determine  a 
capability  to  reconstruct  an  imposed  wind  field 
pattern  from  uniform  and  nonuniform  measure- 
ments in  the  wind  field.  From  this,  a  new 
technique  was  developed  for  application  to 
wind  interpolation  which  represented  an  im- 
provement over  the  Thiessen  polygon  method. 
The  developed  model  provides  an  adequate  in- 
terpolated representation  of  wind  fields  and  at- 
mospheric trajectories  in  real  or  near-real  time 
for  interpretation  of  atmospheric  pollution  and 
hazard  problems.  The  model  can  be  pro- 
grammed on  small  programable  calculators 
with  storage  capability.

A  bathystrophic  storm  surge  numerical  model 
was  verified,  using  data  of  historical  hurricanes 
at  selected  traverses  on  the  Gulf  of  Mexico  and 
the  east  coast,  by  calibrating  coupled'  values 
of  wind  and  bottom  stress  coefficients  in 
hydrodynamic  equations  for  the  numerical 
computation.  These  coefficients  represented 
model  calibration  constants  that  included  more 
than  the  physical  effects  of  wind  and  seabed 
friction.  Surge  hydrographs  were  calculated 
and  compared  with  observed  or  recorded  surge 
hydrographs  of:  (a)  Hurricane  of  1949  at  Gal- 
veston and  Freeport,  Texas;  (b)  Hurricane  Carla 
at  Galveston  and  Freeport,  Texas;  (c)  Hurricane 
Audrey  at  Eugene  Island,  Louisiana;  (d)  Hur- 
ricane Camille  at  Biloxi,  Mississippi;  and  (e) 
Hurricane  Carol  at  Narragansett  Pier,  Rhode 
Island.  Comparisons  were  made  with  theoreti- 
cal results  for  several  hypothetical  storm  surge 
problems  for  which  analytical  solutions  could 
be  obtained.  Although  reasonable  empirical 
solutions  were  obtained  by  combining  values  of 
initial  rise  and  of  coefficients  of  bottom  friction 
and  wind  stress,  the  significance,  variation  and 
interdependence  of  these  parameters  could  not 
be  determined  adequately  because  of  limited 
historical  data.  Extrapolation  of  empirically 
derived  wind  stress  and  bottom  friction  rela- 
tionships, as  determined  from  lower  wind- 
speeds,  to  extreme  probable  maximum  condi- 
tions associated  with  the  synthetic  hurricanes, 
could  not  be  conclusively  verified.  Because  of 
the  complexity  of  the  problem,  data  limitations, 
and  the  variability  of  different  factors  entering 
the  calibration  process,  correlation  for  all 
historical  hurricanes  at  all  traverses  was  dif- 
ficult to  obtain.

The  disturbed  ionospheric  region  produced  by

studied  by  the  use  of  orbital  and  geostationary

This  region  is  centered  at  the  height  of  max- 


imum  of  the  ionospheric  layer  and  displaced 
about  30  km  north  of  the  transmitter.  The 
disturbed  region  is  made  up  of  geomagnetic

m  (the  larger  values  are  at  night).  They  drift  with 
the  neutral  wind  with  velocities  of  8  to  25  m/s.

The  report  is  broadly  divided  into  the  categories 
of  scattering  and  absorption,  with  the  greater 
stress  laid  on  absorption  The  first  of  these  is 
the  so-called  line-by-line  direct  integration 
method,  which  requires  a  detailed  compilation 
of  the  characteristics  of  individual  molecular 
lines.  The  second  of  the  absorption  methods  of 
calculation  presented  is  the  band-model 
technique.  In  this  method,  the  line  spectrum  is 
approximated  by  some  mathematically  manipu- 
latable  distribution  function  with  undetermined 
band-model  parameters.  By  comparison  of  cal- 
culated results  with  laboratory  experimental 
data  the  parameters  are  defined,  and  the  band- 
model  is  used  for  calculating  transmittance 
under  any  required  meteorological  conditions. 
The  third  general  set  of  techniques  is  given  the 
heading  Multi-Parameter  Analytical 

Procedures.'  These  techniques  are  derived 
from  the  band-model  concept,  incorporating  a 
larger  number  of  parameters,  with  presumably 
greater  accuracy  in  the  resultant  calculations. 
The  rest  of  the  report  is  either  tutorial  or  sup- 
portive, presenting  details  of  information  which 
is  required  as  input  to  the  calculation 
procedures.

A  successful  scientific  balloon  flight  mission  is 
dependent   upon   accurate   control   of  vertical 


motion.  The  scientist  wants  a  rapid  ascent  to 
his  altitude  of  interest,  but  this  desire  must  be 
tempered  by  avoiding  aerodynamic  stress 
damage  to  the  balloon.  Reasonable  limits  on  al- 
titude variation  caused  by  temperature  fluctua- 
tion are  desired,  so  effective  management  of 
ballast  is  required  on  zero  pressure  balloons. 
There  are  also  special  situations  with  multiple 
altitude  requirements  that  require  efficient 
management  of  ballasting  and  valving  for  verti- 
cal motion  control.  Empirical  equations  were 
developed  by  the  University  of  Minnesota 
(under  contract  to  ONR  and  jointly  sponsored 
by  the  U.S.  Army,  Navy  and  Air  Force)  before 
1960.  The  night  ascent  technique  frequently 
used  now  also  poses  a  new  environment  regime 
so  it  was  considered  necessary  to  re-evaluate 
the  vertical  motion  response  using  current 
computer  capabilities.

In  this  report,  the  calculation  of  riometer  ab- 
sorption during  several  PCA  events  of  particu- 
lar interest  is  presented.  These  calculations  are 
based  on  earlier  work  in  which  an  improved  ef- 
fective recombination  coefficient  was  derived 
and  an  atmospheric  model  for  (1)  each  month 
of  the  year,  (2)  day  and  night,  and  (3)  60  deg  N 
and  90  deg  N  latitude  was  presented.  In  this  re- 
port, the  calculated  values  of  riometer  absorp- 
tion are  presented  for  5  PCA  events:  2  Nov.  69,  7

The  calculated  values  of  riometer  absorption 
are  compared  with  experimental  values  mea- 
sured for  both  day  and  night  conditions  at

between  riometer  absorption  and  the  square- 
root  of  the  proton  flux  for  nighttime  conditions 
is  presented  This  relationship,  which  has  previ- 
ously been  applied  only  for  daytime  conditions, 
is  discussed  both  on  a  fundamental  level  and 
on  the  level  of  verification  by  comparison  with 


experiment.  In  addition,  the  basic  equation 
widely  used  to  calculate  riometer  absorption  is 
compared  with  the  original  Sen-Wyller  result.

During  the  course  of  this  research  three  global 
climate  models  (I,  II,  and  III)  have  been 
developed.  The  first  two  are  vertically-in- 
tegrated and  use  a  grid  spacing  of  10  deg  of 
latitude  in  the  north-south  direction.  Model  I 
differentiates  zonally  only  between  land  and 
water.  Model  II  uses  a  zonal  grid  of  10  deg  of 
longitude  and  is  the  only  one  of  the  models  to 
include  a  hydrologic  cycle  and  variable  cloud 
cover.  Model  III  is  a  two-dimensional  zonally- 
averaged  model  with  a  grid  spacing  of  7.5  deg 
of  latitude  horizontally  and  3  km  vertically  (10 
layers).  Each  model  has  its  own  advantages  and 
disadvantages.  Model  I  is  probably  the  most 
practical  to  use  in  studies  of  climatic  change. 
The  model  is  fast,  requiring  very  little  computer 
time,  and  reproduces  the  present  climate  of  the 
earth  quite  well.  Models  II  and  III  should  both  be 
improved  considerably  before  being  used  in 
studies  of  climatic  change.  (Author)

Primitive  Equation  Forecast  Model  in  the  63x63 
Northern  Hemisphere  Polar  Stereographic  Grid 
is  described.  In  the  first  step,  an  analysis  is  per- 
formed at  10  mandatory  pressure  levels.  In  the 
second  step,  the  mandatory  pressure  level 
heights  are  transformed  into  sigma  coordinates

procedure  which  describes  the  physical  pro- 
perties of  an  air  column  through  static  stability 
parameters  over  defined  pressure  increments. 
In  the  third  step,  raw  data  are  converted  to 
sigma  coordinates  by  an  identical  procedure 
and  reanalyzed  in  sigma  coordinates  by  using 
the  transformed  pressure  level  analysis  as  ini- 
tial guess.  The  applied  numerical  analysis 
method  is  based  on  the  pattern-conserving 
analysis  technique  FIB  (Field  by  Information 
Blending)  which  allows  wind  and  height  reports 
to  be  treated  as  independent  information  sets 
and  to  be  analyzed  simultaneously.

This  paper  describes  two  mathematical 
methods  for  predicting  temperatures  over  a 
relatively  large  area  when  only  a  small  amount 
of  actual  data  is  known.  Known  temperatures 
from  a  few  locations  are  compared  with  the 
physical  characteristics  of  these  locations  from 
data     gathered     from     standard     topographic 


maps.  The  topographic  data  for  the  unknown 
sites  is  then  recorded  and  a  prediction  is  made 
of  these  site  using  the  data  and  temperatures 
from  the  known  sites.  The  first  method  is  a 
statistical  regression  analysis  which  can  only 
be  done  with  the  aid  of  a  large  computer.  The 
second  method  is  a  simplified  version  of  the 
first  which  can  be  implemented  on  a  smaller 
machine  or  by  hand  if  necessary.  (Author)

Several  highly  successful  versions  of  the  FIB 
were  developed  for  operational  use  at  the  Fleet

restricted  to  the  analysis  of  a  particular  variable

sea  surface  temperature  on  a  fixed  grid  projec- 
tion such  as  the  FNWC  63  x  63  polar  stereo-

described  in  the  report  can  be  used  for  the 
analysis  of  any  scalar  variable  on  a  prescribed 
but  variable  rectangular  domain  The  report  in- 
cludes a  detailed  discussion  of  the  underlying

(LINAVEC02  parameters)  and  parameters  tabu- 
lated in  the  NASA  Handbook  of  Infrared  Radia-

describes  the  low-temperature  variations  of  the 
parameters,  but  is  inadequate  for  high-tem- 
perature applications.  The  latter  set  is  suitable 
for  high-temperature  applications,  but  fails  for 
low-temperature  cases.  Examples  of  the  defi-

of  the  combined  set  are  given,  and  a  tabulation

The  representation  of  the  mean  tropospheric 
flow  by  satellite-derived  cloud-motion  vectors 
is  studied  for  use  in  a  barotropic  hurricane  pre- 
diction model.  The  systematic  use  of  these  vec- 
tors is  considered  over  areas  not  covered  by 
rawinsonde  data  to  aid  the  inital  analysis  of  the 
flow  pattern.  Linear  regression  analysis  is  used 
to  develop  equations  for  the  pressure-averaged 
tropospheric  flow  from  data  at  only  1,  2,  or  3 
levels.  The  equations  are  derived  from  a  large 
sample  of  rawinsonde  observations,  used  as 
simulated  cloud-motion  vectors,  from  the  tropi- 
cal and  subtropical  latitudes  of  the  Northern 
Hemisphere.  The  performance  of  the  regres- 
sion equations  on  independent  data  is  con- 
sidered, as  is  the  loss  of  skill  when  satellite 
winds  are  used  in  the  equations  instead  of 
rawinsonde  winds.  The  satellite  data  is  applied, 
in  a  pilot  study,  to  two  operational  SANBAR

The  High  Plains  Cooperative  Experiment  spon- 
sored by  the  Division  of  Atmospheric  Water 
Resource  Management  of  the  Bureau  of  Recla- 
mation is  a  large-scale  project  to  study  the 
feasibility  of  augmenting  precipitation  in  the 
High  Plains  region  by  artificial  means.  In  July 
1974  a  planning  workshop  was  held  in  Vail, 
Colorado,  at  which  intensive  studies  of  the 
requirements  for  cloud  modeling,  measure- 
ments, and  design  and  evaluation  were  made. 
One  recommendation  that  came  from  the 
modeling  sessions  was  that  of  the  models 
developed  by  the  various  participants  be  tested 
with  the  same  set  of  data,  and  that  another 
workshop  be  convened  to  compare  the  results 
This  was  done,  and  the  modeling  workshop  was 
held  in  Denver  on  11-13  June  1975.  Approxi- 
mately 14  participants  presented  results  of  their 
models.  Data  for  two  days,  10  and  17  August 
1973,  for  the  St.  Louis  region  from  Project 
METROMEX  were  provided.  The  remainder  of 
the  workshop  was  devoted  to  working  up 
recommendations  for  observations  to  be  made 
during  the  high  Plains  Experiment  both  for  ini- 
tialization and  verification  of  the  model.

The  AIRCHEM  code  has  been  used  to  calculate 
the  time  evolution  of  ionic  and  neutral  species 
during  a  10  raised  to  the  third  power-second 
bombardment  of  airlike  N2:02  mixtures  at  p()2 
and  5  Torr  and  300K  by  1-MeV  electrons.  To  test 
the  sensitivity  of  the  predictions  to  assumptions 
regarding  the  production  rates  of  specific 
atomic  and  molecular  ionic  and  metastable 
species  in  collisions  of  energetic  electrons  with 
N2  and  02  molecules,  three  sets  of  rates  cur- 
rently used  by  aeronomists  were  employed,  as 
tabulated  below;  here  Q(X)  is  the  number  of  X 
produced  per  secondary  electron.  The  im- 
portance of  Q(N2D)  on  the  buildup  of  NO  and 
N02,  and  on  the  resulting  behavior  of  03,  is 
demonstrated  Implications  to  the  ion  spectra 
are  pointed  out.  Effects  of  assumed  initial  con- 
centrations of  N02  in  the  10  raised  to  -7 
through  10  raised  to  -8  range  are  noted.  Ion 
spectra  obtained  in  the  laboratory  during  elec- 
tron bombardment  of  airlike  N202  mixtures 
containing  traces  of  H20  and  C02,  at  2  and  5 
Torr,  were  compared  with  the  predictions 
based  on  AIRCHEM  Many  features  of  the  ion 
spectra  agree  with  theory.  Thus,  the  general 
ionic  composition  of  the  laboratory  plasma  is  as 
expected.

sociated with  large  electric  EMP  fields  were, 
however,  neglected  in  order  to  narrow  the

proach may  be  usable,  but  the  coefficients  em-

in  the  case  of  a  complicated  species  such  as 
water  vapor.  Cluster  conditions  in  the  tempera- 
ture range  210-295  K  and  the  vapor  pressure 
are  calculated  throughout  the  collapse  of  a  su- 
persaturated metastable  vapor  An  effective 
molecular  pair  interaction  energy  and  nearest 
neighbor  coordination  number  is  found  based 
on  the  classical  zero-point  enthalpy  of  sublima- 
tion and  by  iteration  to  satisfy  initial  equilibrium 
limiting  constraints  at  273  K.  The  internal  ener- 
gy redistribution   frequency  results  from  close

matching  of  the  experimental  pressure  distribu- 
tion. A  method  of  determining  the  cluster  size  at 
which  macroscopic  properties  become  relevant 
is  described;  the  size  is  found  to  be  a  cluster  of 
about  122  molecules  at  273  K  based  on  a  hard 
sphere  model  collision  cross  section.  For  the 
water  vapor  dimer  an  equilibrium  constant  of  4 
x  10  to  the  -21st  power/cc  is  found  at  273  K 
compared  to  3.1  x  10  to  the  -21st  power/cc  ob- 
tained from  Keyes  data.  Two  models  for  water 
vapor  clusters  result  (from  satisfying  all  con- 
straints imposed  on  the  theory)  which  are  given 
in  terms  of  number  of  nearest  neighbors,  pair 
interaction  energy  per  molecule  (2.9kcal/mol  at 
273  K)  and  possible  structure  on  a  cluster  by 
cluster  basis  for  a  classical  hard  sphere  model 
and  for  a  model  approximating  a  Pauling  type

According  to  the  linearized  solutions  for  ther- 
mal blooming,  the  density  perturbations 
become  infinite  (i.e.  'catastrophic'  defocusing) 
as  the  Mach  number  approaches  unity.  How- 
ever, the  nonlinearities  in  the  transonic  equa- 
tions cutoff  the  trend  to  infinity,  and  the  values 
of  the  flow  perturbation  quantities  are  finite. 
The  nonlinear  equations  with  heat  addition  are 
transformed  into  simple  linear  algebraic  equa- 
tions through  the  specification  of  the  stream- 
line geometry  in  the  heat  release  region.  At  a 
Mach  number  of  unity,  streamtube  area  varia- 
tion was  found  to  be  directly  proportional  to  the 
change  in  total  temperature.  A  steady,  two- 
dimensional  mixed  flow  solution  has  been 
found  for  the  transonic  thermal  blooming 
problem.  The  solution  for  the  density  perturba- 
tions within  a  laser  beam  at  a  Mach  number  of

A  comprehensive  description  of  the  discrete- 
ordinate  method  for  the  transfer  of  infrared 
radiation  in  an  isothermal  cloud  layer  is 
presented  Applications  of  such  a  method  to 
non-isothermal,  inhomogeneous  atmospheres 
containing  cirrus  clouds  are  carried  out  and  a 
listing  of  the  computational  code  of  the  infra  red 
radiation  program  is  given  in  the  Appendix  of 
this  report  On  the  basis  of  this  radiation  pro- 
gram which  allows  non-isothermal  as  well  as 
non-homogeneous  structures  of  clouds,  radia- 
tive properties  of  cirrus  clouds  are  investigated 
in  the  10  micrometers  window  region  Effects  of 
non-isothermal  structure  of  cirrus  are  shown  to 
be  important  when  its  thickness  is  greater  than 
about  3  km     In  addition,  we  also  find  that  it 


seems  inappropriate  to  define  an  'emissivity'  of 
a  non-isothermal  cloud.  Utilizing  the  concept  of 
transmissivity  derived  from  radiative  transfer 
analyses,  a  retrieval  technique  is  developed  for 
the  determination  of  the  surface  temperature, 
the  cirrus  cloud  thickness  and  its  transmissivity 
at  a  reference  wavenumber  and  the  fraction  of 
cirrus  cloudiness.  Error  analyses  employing  cli- 
matological  data  reveal  that  independent  ran- 
dom errors  in  temperature  and  humidity 
profiles  introduce  insignificant  errors  in  the 
four  resulting  parameters.  Based  on  the 
retrieval  procedures  we  illustrate  that  the  verti- 
cal ice  content  may  be  estimated  assuming  that 
ice  particles  are  randomly  oriented  in  a

ICECAP  is  an  auroral  measurements  program

disturbed  ionosphere  These  codes  are  needed 
to  assess  and  evaluate  the  operation  of  critical

The  liquid  water  content  (LWC)  in  clouds  in  a 
three  dimensional  reference  system  is  an  im- 
portant input  parameter  for  operational 
forecast  models  and  for  design  problems  of 
systems  that  operate  in  the  atmosphere.  The 


12 


LWC  can  be  calculated  from  the  cloud's  drop- 
size  distribution.  An  accurate  estimate  of 
LWC/DSD  depends  upon  knowing  the  cloud 
type,  air  mass  type,  ambient  temperature,  cloud 
age,  geographical  locations,  degree  of  satura- 
tion, and  the  general  meteorological  condition. 
Estimates  of  these  parameters  can  be  obtained 
from  the  global  cloud  analysis  and  the  10-level 
synoptic  parameter  analysis  data  bases  which 
are  produced  by  the  Air-Force  Global  Weather 
Central.  A  percentage  of  the  maximum  LWC 
possible  for  precipitating  and  non-precipitating 
clouds  in  a  layer  times  the  percentage  of  cloud 
coverage  yields  the  LWC  for  that  volume.

A  special  chamber  for  measuring  the  off-axis

systems  was  designed  and  constructed.  The 
ambient  background  power  level  caused  by  at- 
mospheric scattering  was  reduced  by  using 
high-efficienty  particulate  filters  to  remove  the 
atmospheric  aerosols  and  produce  a  clean-

tering were  reduced  by  using  specular  surfaces 
in  a  modified  cylindrical  shape  to  direct  the 
scattered  radiation  away  from  the  baffle  en- 
trance. Two  computer  programs  were  used  to 
predict  the  magnitudes  of  the  atmospheric  and 
surface  scattering  Measurements  which 
separated  the  atmospheric  scattering  from  the

(molecular)  scattering  was  determined  to  be  the 
limiting  mechanism  in  achieving  a  low

The  Global  personality  of  radiowave  charac- 
teristics such  as  amplitude  scintillation  S4  and 
group  path  delay  may  be  graphically  displayed 
through  use  of  a  plotting  code  in  conjunction 
with  existing  scintillation  and  electron  density 
models.  The  Fremouw-Rino-Pope  model  is 
used  for  deducing  average  scintillation  at- 
trlbutes  and  the  Ching-Chiu  Model  is  used  for 
deducing  average  electron  density.  The  former 
model  is  used  directly  and  the  latter  model  is  in- 
tegrated to  obtain  the  total  electron  content  of 
the  ionosphere.  Since  the  total  electron  content 
(TEC)  is  proportional  to  the  group  path  delay, 
plots  of  TEC  are  provided  in  the  manuscript  in- 
stead of  the  delay  characteristic.  Examples  of 
both  S4  and  TEC  are  given  for  various  environ- 
mental, diurnal,  and  seasonal  conditions.

A  two-dimensional  time-dependent  numerical 
storm  surge  model  using  orthogonal  curvilinear 
coordinates  is  presented  The  curvilinear  coor- 
dinate system  is  based  on  a  conformal  mapping 
ot  the  interior  region  bounded  by  the  actual 
coast,  the  seaward  boundary  (taken  as  the  180- 
meter  depth  contour)  and  two  parallel  lateral 
boundaries  into  a  rectangle  in  the  image  plane. 
Three  regions  of  the  Continental  Shelf  of  the 
Gulf  of  Mexico  and  two  regions  of  the  eastern 


seaboard  of  the  United  States  are  mapped 
Since  the  transformation  is  conformal,  the  as- 
sociated modifications  of  the  vertically  in- 
tegrated equations  of  motion  and  mass  con- 
tinuity are  minimized.  The  coast,  seaward 
boundary,  and  the  lateral  boundaries  of  the 
computing  grid  are  straight  lines  in  the  image 
plane  thus  facilitating  the  application  of  the 
boundary  conditions.  The  final  coordinates 
allow  for  the  greatest  resolution  near  the  coast 
in  a  central  area  of  principal  storm  surge 
development  and  modification.  The  model  is 
employed  in  the  simulation  of  the  storm  surge 
induced  by  Hurricanes  Carla  (1961)  and  Camille 
(1969)  which  crossed  the  gulf  coast  of  the

tations. (Author)

(particularly  lightning)  and  identifying  feasible 
protective  systems.  After  a  brief  introductory 


section  math  models  of  effects  of  tethered  bal- 
loons on  surrounding  electrical  field  are 
presented.  These  models  are  then  compared 
with  measurements  taken  during  extensive

SOVEL  was  written  as  part  of  the  Ocean  Ther-

pose is  to  extract  the  temperature  and  salinity 
levels  (by  one-degree  squares)  in  desired  loca- 
tions from  an  ocean  climatology  tape.  It  takes 
the  corresponding  analyzed  sea-surface  tem- 
perature and  the  mixed  layer  depth  at  given  lo- 
cations which  are  read  from  input  cards  and  ad- 
justs the  upper  standard  levels  to  these 
parameters.  An  additional  feature  of  the  pro- 
gram is  the  adjustment  of  the  temperature  and 
salinity  gradients  below  the  mixed  layer  depth. 
These  gradients  can  be  sharp  indeed  in  the 
Mediterranean.  Their  sharpness  varies  with 
various  parameters  and  seasons  and  this  varia- 
tion has  been  taken  directly  into  consideration 
with  this  program  .  (Author)

Using  Mie  calculations  for  a  wide  variety  of 
measured  and  assumed  particle  size  distribu- 
tions, a  strong  relationship  between  the  total 
volume  content  of  the  particulate  along  the 
transmission  path  and  the  aerosol  extinction 
coefficient  was  established.  Field  measure- 
ments, such  as  those  taken  at  Grafenwoehr, 
Federal  Republic  of  Germany,  further 
established  the  validity  of  this  relationship. 
Both  theory  and  experiment  suggest  that  a 
phenomenological  scaling  of  photopic  trans- 
mission (related  to  normal  meteorological  visi- 
bility) to  the  infrared  (IR)  windows  is  possible 
which  furthermore  is  independent  of  the  struc- 
ture or  shape  of  the  particle  size  distribution.  A 
second  important  implication  is  that  a  simple, 
possibly  remote  measurement  of  a  quantity  re- 
lated to  the  volume  or  mass  of  the  aerosol  could 
provide  a  direct  measure  of  the  IR  transmission 
(an  IR  visibility  meter).  Such  a  routine 
meteorological  measurement  would  clearly  be 
of  use  to  sensor  performance  modeling.

A  quantitative  model  of  the  magnetospheric 
magnetic  field  and  associated  procedures  for 
accurately  cataloging  charge  particle  data  out 
to  and  beyond  geosynchronous  orbit  is 
developed.  The  magnetic  field  model  incor- 
porates all  major  magnetospheric  current 
systems  and  is  valid  for  all  tilt  angles;  i.e.,  an- 
gles of  incidence  of  the  solar  wind  on  the  dipole 
axis.  The  model  accurately  represents  the  total 
magnetospheric  magnetic  field  for  conditions 
of  low  magnetic  activity  and  to  a  geocentric 
distance  of  15  earth  radii  or  to  the  mag- 
netopause. A  new  (B,  I)  coordinate  system  is 
developed  to  more  accurately  organize  charged 
particle  data.  The  electric  field  produced  by  the 
daily  varying  tilt  angle  is  computed.  (Author)

to  develop  a  capability  for  full  description  (from

include  second-order  signal  statistics  in  the 
temporal,  spatial,  and  spectral  domains.  The 
first  priority  in  the  follow-on  work  will  be  to  cal-

A  potential  function  is  presented  for  the  force 
by  which  the  atmospheric  tide  bulge  acts  on  or- 
bits of  artificial  earth  satellites.  The  tidal  bulge 
is  assumed  to  result  from  the  fact  that  the  earth 
rotates  within  the  field  of  lunar  mass  attraction, 
the  latter  being  inhomogeneous  across  the  ter- 
restrial globe.  Only  the  main  term  of  the 
semidiurnal  tide  is  considered  in  this  report 
The  perturbing  acceleration  associated  with  the 
tide  potential  is  also  specified.  The  latter  is  in- 
tended for  use  with  computer  programs  for

Computer  techniques  are  developed  to  home 
the  ray  at  a  specified  location  with  specified  ac- 
curacy. Several  methods  have  been  in- 
vestigated whereby  oblique  radio  propagation 
data  can  be  used  to  obtain  ionospheric  profiles. 
In  one  method  the  optimum  quasiparabolic 
layer  can  be  found  that  is  supposed  to  fit  the 
given  data  within  a  tolerable  error.  Another 
method  makes  use  of  the  Backus-Gilbert  inver-

This  report  describes  the  development  of  two 
subelements  of  the  U.S.  Army  Experimental 
Prototype  Automatic  Meteorological  System 
(EPAMS).  One  of  the  subelements  is  a  diag-

matic calculation  of  the  mixing  depth,  as  well  as 
the  wind  velocity  and  other  meteorological 
parameters  in  the  surface  mixing  layer,  for  a 
mesoscale  calculation  grid  in  complex  terrain 
The  output  from   this  routine  is  used  with  the

plication routinet-to  calculate  concentra- 
tion/dosage fields  produced  by  pollutant  emis-

calculation  grid.  A  two-layer  shallow-fluid  nu- 
merical model  is  used  in  the  diagnostic  routine 
to  calculate  the  mesoscale  wind  field.  The  con- 
centration/dosage fields  calculated  by  the 
transport/diffusion  application  routine  are  ob- 
tained by  solving  generalized  dispersion 
models  for  both  continuous  and  instantaneous 
sources.  In  addition  to  descriptions  of  the 
modeling  techniques,  calculation  procedures 
and  computer  program  operations,  example

This  paper  presents  the  results  of  Monte  Carlo 
calculations  of  reflected  sunlight  and  air  emis- 
sion in  the  2.653  micrometers  to  2.760 
micrometers  wavelength  band  for  sa'.ellite- 
based  detectors  viewing  a  cumulus  cloud 
loaded  with  various  amounts  of  Sahara  dust 
positioned  between  14  and  15  km  altitude  The 
results  of  the  calculations  showed  that  the 
presence  of  a  dust  loading  of  .00005  cu.  cm.  of 


Sahara  dust  per  m  cubic  meter  of  the  cloud 
probably  cannot  be  detected  at  that 
wavelength.  Increasing  the  dust  loading  to  the 
cloud  by  a  factor  of  100  or  more  gave  results 
that  indicated  that  the  presence  of  the  dust 
could  be  determined  by  the  use  of  reflected 
sunlight  in  the  2.7  micrometers  wavelength 
band.  Mie  calculations  for  both  the  cloud  and 
Sahara  dust  indicates  that  the  best  wavelength 
for  detection  of  the  air  emission  would  be 
wavelengths  near  10  micrometers.  Additional 
calculations  are  in  progress  for  other 
wavelengths  in  the  2  micrometers  to  15 
micrometers  wavelength  range.

which  can  be  used  to  calculate  the  trans-

to  the  middle  infrared  portion  of  the  spectrum 
(0.25  to  28.5  micrometers)  at  a  spectral  resolu- 
tion of  20  cm.  The  major  additions  are  the  inclu- 
sion of  water  vapor  continuum  attenuation  in 
the  3.5  to  4.2  micrometers  region,  and  a  tem- 
perature dependence  to  the  H20  continuum  at- 
tenuation coefficient  in  both  the  4  micrometers 
and  10  micrometers  regions.  The  contribution 
of  foreign  gas  broadening  in  the  8-14  microme-

models  are  included  in  this  supplement.  These 
include  three  boundary  layer  aerosol  models 
for  maritime,  urban,  and  rural  conditions  in  the 
lower  2  km  of  the  atmosphere,  and  a  tropo- 
spheric  model  for  use  mainly  above  1  or  2  km 
altitude.  The  rural  model  is  a  replacement  for 
the  average  continental  model  presently  in 
LOWTRAN  3.  A  temporary  provision  is  also 
given  to  accommodate  fog  conditions  when  the 
visual  range  falls  below  2  km.  (Author)

Measurements  have  been  made  of  the  apparent 
rotational  temperature  of  02  (b(1  )Sigma(g0))  at- 
mospheric (0,1)  band  emissions.  The  data  were 
taken  at  nighttime  in  the  auroral  zone  at  Poker 
Flat,  Alaska,  on  March  1,  1975.  The  average  ap- 
parent temperature  was  210  k  and  the  zenith 
radiance  of  the  band  was  500  R  (uncorrected 
for  atmospheric  extinction).  A  comparison 
technique  was  developed  to  compare  the  band 
shape  of  the  measured  band  with  theoretical 
spectra  synthesized  at  different,  but  specific, 
rotational  temperatures.  Three  methods  of 
comparison  were  used  and  it  was  concluded 


that  a  sum  of  squares  weighting  approach  is 
near  optimal  for  estimating  rotational  tempera- 
tures. The  effect  of  noise  was  tested  by  adding 
real  typical  noise  to  the  synthetic  model.  The 
same  comparison  technique  was  then  applied 
to  assess  the  benefits  of  noise.  The  uncertainty 
of  the  measurement  is  estimated  to  be  5  K.  A 
'wavelike'  fluctuation  of  the  apparent  rotational 
temperature,  with  a  period  on  the  order  of  1/2 
to  1  hour,  was  observed.  The  fluctuation  on  this 
occasion  appeared  to  covary  with  the  intensity 
of  the  OH  airglow  emission.

This  report  describes  the  Medium  Resolution 
Data  Analysis  Code  (MRDA)  which  is  a  com- 
puter software  code  developed  to  run  on  the 
HP2100  mini-computer  at  the  Air  Force 
Geophysics  Laboratory.  The  code  calculates 
the  atmosphere  transmittance  of  radiation  in 
the  1800-6000/cm  range.  The  code  can  be  used 
for  a  variety  of  paths(horizontal,  vertical, 
downward,  to  space,  etc).  The  user  has  the  op- 
tion of  using  either  the  1962  U.S.  Standard 
Model  atmosphere  or  radiosonde  data. 
Because  of  size  restriction  on  the  HP2100, 
MRDA  is  dividied  into  seven  overlays.  The  spec- 
tral absorption  coefficients,  which  are  calcu- 
lated from  the  AFGL  compilation  of  molecular 
line  parameters  (HITRAN),  are  accessed  from  a 
data  tape.  The  transmittance  calculated  for 
horizontal  paths  near  sea  level  agree  with  those 
calculated  with  HITRAN,  but  MRDA  tends  to 
overestimate  the  absorption  in  the  neighbor- 
hood of  strongly  absorbing  lines.  Some  recom- 
mendations for  further  upgrading  of  the  code 
are  given.  (Author)

Suppressed',  as  used  here,  implies  masking  of

Attention  must  be  applied  to  the  entire  spec- 
trum of  interest  (1-16  microns)  and  over  long 
paths  (such  as  40  air  masses  for  a  line  of  sight 
tangent  to  the  horizon).  This  is  because  the 
signatures  of  self  emitting  sources  are  in- 
fluenced by  the  relatively  short  intervening 
paths  and  generally  dominate  some  spectral  in- 
terval. The  body  contrast  signature,  however,  is 
comprised  from  remote  sources  (i.e.  sun,  sky, 
albedo,  etc.)  which  traverse  long  atmospheric 
paths  to  illuminate  the  target  and  this  signal  is 
contrasted  against  a  remote  background 
(horizon,  terrain,  clouds,  etc.)  whose  radiance

Patches  of  ionized  air  produced  by  the  passage 
through  the  atmosphere  of  beta  radiation 
emitted  from  nuclear  debris  clouds  pose  a 
potential  threat  to  satellite  communications. 
The  distribution  of  the  debris  and  the  con- 
sequent ionization  has  been  shown  to  be 
strongly  a  function  of  the  mesospheric  wind 
fields.  Observational  data  for  these  wind  fields 
is  shown,  upon  analysis,  to  be  inadequate  for 
systems  application  and  theoretical  models 
have  been  developed  to  remedy  this.  The  circu- 
lations in  the  upper  atmosphere  are  driven  by 
the  time-dependent  influx  cf  solar  radiation 
which  is  represented  by  a  heating  function  used 
as  input  to  the  general  circulation  models.  An 
improved  heating  function  has  been  obtained

Two  preliminary,  alternative  models  of  the  high- 
altitude  (h  ()  or  0  90  km)  neutral-particle  motion 
have  been  adopted  for  use  in  ROSCOE.  Both 
models  are  one-dimensional  spherical  Lagran- 
gian models  and  describe  the  vertical 
hydrodynamic     motion     in     each     geocentric 


column  in  an  array  of  perhaps  100  such  con- 
tinuous but  independent  columns  covering  the 
disturbed  region  of  interest.  The  models 
(SAIHYD,  NRLHYD)  describe  the  motion  of  a  set 
of  either  Lagrangian  cells  or  points  by  using  the 
method  of  either  difference  equations  or  dif- 
ferential quadrature,  respectively.  Both  models 
have  automatic  rezone  capability.  The  geocen- 
tric columns  defining  the  geometry  for  the  cal- 
culations are  described  in  terms  of  an  arbitrarily 
positioned  and  oriented  quadrupole  coordinate 
system.  Each  Lagrangian  cell  or  point  is 
characterized  by  not  only  the  hydrodynamic 
properties  but  also  a  set  of  chemistry  quanti- 
ties. The  chemistry  is  loosely  coupled  to  the 
hydrodynamics.  Herein  are  presented  details  of 
the  quadrupole  coordinate  system,  the  working 
form  of  the  hydrodynamic  equations  and  their 
initialization  and  methods  for  solution,  the 
results  of  a  test  problem  for  a  large-yield  event 
at  200-km  altitude  producing  motion  in  a  linear 
array  of  six  columns.  (Author)

Models  of  the  high-altitude  debris-energy  parti- 
tion and  deposition  have  been  adopted  for  use 
in  ROSCOE.  The  models  for  the  debris-energy 
partition  and  heavy-particle  source  spectra  in- 
corporate the  work  of  Crevier  and  Kilb  for  the 
loss-cone  and  ion-leak  particles.  The  deter- 
mination of  the  total  (and  spectrum  of  the)  UV 
portion  of  the  kinetic  yield  remaining  after  that 
assigned  to  all  the  heavy-particle  motion  is 
based  on  the  work  of  Fajen  and  Sappenfield. 
Representative  points  in  the  spatial  distribution 
function  specified  for  the  loss-cone  and  ion- 
leak  particles  are  used  as  effective  source 
points  through  which  magnetic  field  lines  are 
traced  in  the  downward  direction  through  the 
intercepted  grid  cells  in  the  geocentric  quadru- 
pole coordinate  system.  Conventional  heavy- 
particle  range-energy  theory  is  employed  along 
these  paths,  without  regard  to  spiralling  effects, 
to  deposit  the  energy  of  these  heavy  particles  in 
the  traversed  cells.  Charge-exchange  particles 
are  deposited  without  regard  to  the  magnetic 
field.  The  total  heavy-particle  energies 
deposited  by  inelastic  and  by  elastic  collisions 
in  each  cell  are  partitioned  into  various  modes 
and  species  which  are  ultimately  made  com- 
patible with  the  late-time  grid  chemistry.  The 
UV  energy  groups,  as  well  as  the  x-ray  energy, 
are  deposited  by  tracing  ray  paths  (and  con- 
structing line  integrals  of  relevant  species)  from 
the  event  point  to  each  cell  in  the  high-altitude 
grid  treated  as  a  target  cell.

Methods  are  described  for  solving  the  diffusion 
equation  for  trapped  particles  precipitating  in 
the  ionosphere.  It  is  shown  that  the  variation  of 
the  particle  distribution  with  spatial  location, 
both  latitudinal  and  longitudinal,  must  be  con- 
sidered, and  that  the  bounce  averaged  diffusion 
equations  are  inadequate  to  treat  the  loss-cone 
distributions.  The  coupling  of  precipitating  par- 
ticles to  the  ionosphere  is  described,  with  appli- 
cations of  the  AURORA  doce.  Mid-latitude 
WIDEBAND  observations  are  described,  with  a 
discussion  of  interpretations  based  on  trapped 
particle  precipitation.  Recent  observations  are 
described  of  loss-cone  distributions  of  ions  and 
electrons  which  do  not  fit  the  simple  diffusion 
model.  It  is  shown  that  these  observations  can 
be  accounted  for  by  the  presence  of  kilovolt 
electric  fields  aligned  with  the  magnetic  field.  It 
is  shown  that  the  ionosphere  at  large  distances 
from  a  high-altitude  nuclear  explosion  may  be 
unstable  to  the  Farley-Buneman  mechanism, 
thereby  providing  a  new  mechanism  for  iono- 
spheric irregularities.  (Author)

The  SSJ/3  sensor  is  designed  to  measure  elec- 
trons from  50  eV  to  20  keV.  This  is  accom- 
plished by  using  two  head  assemblies  with 
common  signal  processing  and  voltage 
sources.  The  low-energy  head  assembly  selects 
50.0  to  1,000  eV  electrons  over  eight  channels 
with  a  normalization  factor  H  0  0.000043  sq  cm- 
ster.  The  high-energy  assembly  similarly  selects 
1  00  to  20  0  keV  electrons  over  eight  channels 
with  an  H-factor  equal  to  0.000013  sq  cm-ster. 
Energy  resolution  is  approximately  10%  for  an 
isotropic  incident  flux.  An  electron  beam  was 
used  to  determine  angular  and  energy 
response.  These  measurements  were  com- 
pared with  results  from  a  Monte-Carlo  com-

to  determine  the  final  normalizations.  (Author)

from  the  Weather  Message  Switching  Center 
for  incorporation  into  the  PATWAS  message, 

(6)  reduction  in  the  time  required  for  updating, 

(7)  addition  of  more  meteorological  and

task  of  providing  and  maintaining  Maritime 
Aids  to  Navigation.  These  aids  are  located  on 
and  near  the  coastline  and  inland  waters  of  the 
United  States  and  its  possessions.  A  computer 
program.  Design  Synthesis  and  Performance 
Analysis  (DSPA),  has  been  developed  by  the  Jet 
Propulsion  Laboratory  to  demonstrate  the 
feasibility  of  low-cost  solar  array/battery  power 
systems  for  use  on  flashing  lamp  buoys.  To  pro- 
vide detailed,  realistic  temperature,  wind,  and 
solar  insolation  data  for  analysis  of  the  flashing 
lamp  buoy  power  systems,  the  two  DSPA  sup- 
port computer  program  sets:  MERGE  and  STAT 
were  developed  A  general  description  of  these 
two  packages  is  presented  in  this  program 
summary  report.  The  MERGE  program  set  will 
enable  the  Coast  Guard  to  combine  tempera- 
ture and  wind  velocity  data  (NOAA  TDF-14 
tapes)  with  solar  insolation  data  (NOAA  DECK- 
280  tapes)  onto  a  single  sequential  MERGE  file 
containing  up  to  12  years  of  hourly  observa- 
tions. This  MERGE  file  can  then  be  used  as 
direct  input  to  the  DSPA  program.  The  STAT 
program  set  will  enable  a  statistical  analysis  to 
be  performed  of  the  MERGE  data  and  produce 
high  or  low  or  mean  profiles  of  the  data  and/or 
do  a  worst  case  analysis  The  STAT  output  file 
consists  of  a  one-year  set  of  hourly  statistical 
weather  data  which  can  be  used  as  input  to  the 
DSPA  program.

A  preliminary  model  of  the  ambient  atmosphere 
and  ionosphere  has  been  adopted  for  use  in 
ROSCOE.  The  model  provides  at  all  altitudes  all 
the  needed  properties  of  the  neutral  at- 
mosphere, including  a  dependence  on  the  solar 
cycle  and  the  local  (apparent)  time  for  altitudes 
above  120  km.  Analytic  fit-functions  to  Myers 
minor-species  data  base  provide  all  the  minor 
neutral  species  (O,  C02,  N,  NO,  H20,  02(1  delta 
g),  03,  and  N02)  required  by  the  chemistry 
module.  Interim  electron  density  profiles  and 
effective  ion  production  rates  serve  as  the  basis 
for  the  ionospheric  model.  Herein  are 
presented  derivations,  flow  diagrams,  Fortran 
listings,  and  test  problems.  (Author)

the  several  possible  energy  loss  mechanisms 
from  high  altitude  nuclear  bursts  referred  to  as 
the  LOSS  CONE  and  the  ION  LEAK.  The  LOSS 
CONE  represents  the  escape  of  debris  into  the 
narrow  cone  of  angles  parallel  to  the  magnetic 
field  in  which  the  Larmor  coupling  theory  is 
either  inapplicable  or  partially  fails.  The  ION 
LEAK  represents  the  loss  of  energy  due  to  ions 
that  at  any  stage  receive  a  velocity  component 
parallel  to  the  field  that  is  sufficient  to  allow 
them  to  escape  along  that  direction.  (Author)

velocity  spectrum  breadth  observations  in 
defining  severe  turbulence  areas.  The  mean

This  work  is  concerned  with  predicting  the  tem-

which  has  propagated  through  the  turbulent  at-

general  but  compact  mathematical  expression 
for  the  temporal  scintillation  spectrum  of  an  un- 
specified source  field  with  an  arbitrary  shaped 
extended  receiver  aperture.  This  formula, 
which  is  restricted  to  the  weak  turbulence 
regime,  is  then  applied  to  the  analysis  of  several 
situations  of  contemporary  interest.  Specifi- 
cally, the  analysis  is  directed  toward  the 
description  of  the  effects  of  such  a  laser  beam 
which  is  blemished  in  a  deterministic  sense. 
Spectra  obtained  under  these  conditions  are 
shown  to  display  increased  sensitivity  to  the

A  rapid  and  accurate  approximation  to  the 
Lorentz  line  molecular  absorption  coefficient 
has  been  developed  which  significantly 
reduces  the  time  of  line-by-line  transmittance 


calculations.  By  separating  computations 
required  for  each  spectral  line,  atmospheric 
level,  and  absorbing  gas  under  consideration, 
arithmetical  operations  are  minimized.  Time 
tests  were  conducted  while  computing  the 
monochromatic  absorption  coefficient  for  five 
frequency  channels  in  the  4.3  micrometers 
band.  The  approximation  was  compared  to  the 
evaluation  of  the  Lorentz  line  shape  (Standard 
manner)  for  a  33  level  atmosphere  and  an 
average  of  1000  absorption  lines  per  region. 
Absorption  coefficient  values  computed  by  this 
approximation  agreed  to  those  computed  in  the 
standard  fashion  to  at  least  three  decimal 
places  regardless  of  molecule  type,  channel,  or 
atmospheric  level.  Average  percent-relative  er- 
rors were  typically:  .0001  for  H20;  .0001  for 
C02:  .001  for  N20;  .00000001  for  CO.  For  trans- 
mittance calculations  over  a  band,  time  savings 
can  be  predicted  by  analyzing  the  required 
number  of  arithmetical  operations.  For  1,000 
spectral  lines  over  a  bandwidth  of  25/cm  and  a 
step  increment  of  0.02/cm,  a  reduction  in  com- 
putation time  of  450%  is  anticipated.

Electron  density  measurements  made  with  the

model  is  a  modification  of  the  RADC-POLAR 
model  developed  by  Elkins  and  coworkers  for 
use  in  raytracing  codes  for  HF  propagation  pre- 
diction. Because  the  existing  RADC  model  was 
derived  from  a  larger  and  more  geographically 
extensive  data  base  than  that  used  in  this  study, 
many  of  its  features  have  been  retained  in  the 
new  model  The  major  modification  that  we 
made  was  an  improved  specification  of  the  au- 
roral E-layer  and  the  altitude  interval  between 
the  E  and  F  regions  This  region  sometimes  acts 
as  a  duct  in  which  HF  signals  may  travel  for 
great  distances  without  traversing  the  D  region,

Wind  shear  at  low  altitudes  in  the  terminal  area 
has  been  identified  as  hazardous  to  aircraft 
operations.  Mathematical  models  of  wind 
profiles  have  been  developed  for  use  in  fast 
time  and  manned  flight  simulation  studies 
aimed  at  defining  and  eliminating  these  wind 
shear  hazards.  A  set  of  wind  profiles  and  as- 
sociated wind  shear  characteristics  for  stable 
and  neutral  boundary  layers,  thunderstorms, 
and  frontal  winds  potentially  encounterable  by 
aircraft  in  the  terminal  area  are  given.  Wind 
shear  is  defined  as  significant  changes  in  wind 
speed  and/or  direction  up  to  500  m  above  the 
ground  that  may  adversely  affect  the  approach, 
landing,  or  takeoff  of  an  aircraft.  Engineering 
models  of  wind  shear  for  direct  hazard  analysis 
are  presented  in  mathematical  formulae, 
graphs,  tables,  and  computer  lookup  routines. 
The  wind  profile  data  utilized  to  establish  the 
models  is  described  as  to  location,  how  ob- 
tained, time  of  observation  and  number  of  data 
points  up  to  500  m.  These  models  provide  the 
three  components  of  wind  speed  in  two-dimen- 
sional vertical  planes,  i.e.,  as  functions  of  the 
vertical  and  horizontal  coordinates.  Statistical 
data  is  provided,  where  available,  as  to  the  risk 
of  exceeding  the  wind  shear  environment  pre- 
dicted by  the  models.

analysis  of  scalar  and  vector  fields  was 
developed.  The  technique  is  called  the  Fields  by 
Information  Blending  (FIB)  technique.  This  re- 
port describes  the  results  of  a  research  study  to 
evaluate  the  application  of  the  FIB  technique  to 
the  blending  of  satellite-derived  cloud  motion 
wind  data  and  their  finite-difference  derivatives 
(e.g.,  vorticity  and  divergence)  with  conven- 
tional wind  analyses.  The  FIB  program  was  sup- 
plied to  SRI  by  NEPRF  as  part  of  a  set  of  com- 
puter programs  that,  after  adaption  to  SRI's 
CDC-6400  computer,  allowed  for  the 
processing,  analyses,  and  subsequent  blending 
of  selected  trial  data  sets.  Conclusions  are 
based  on  the  results  obtained  by  executing  FIB 
on  the  data  of  two  case  studies,  one  of  the 
passage  of  Hurricane  Carmen  through  the  Gulf 
of  Mexico  (1-7  September  1974)  and  the  other 
of  migration  of  an  extratropical  cyclone  in  the 


eastern  North  Pacific  Ocean  (5-8  February 
1976).  Both  areas  are  over  water  and  are  rela- 
tively sparse  in  conventional  data,  so 
meteorological  analyses  could  benefit  from  the 
assimilation  of  cloud  motion  data.  It  is  con- 
cluded that  the  FIB  program  and  its  associated 
program  segments  are  operationally  suitable 
for  blending  cloud  motion  data  with  conven- 
tional wind  analyses.

A  computer  program  is  described  which  ena- 
bles one  to  compute  the  pressure  waveform  at  a 
distant  point  following  the  detonation  of  a 
nuclear  explosion  in  the  atmosphere.  The 
theoretical  basis  of  the  program  and  the  numer- 
ical methods  used  in  its  formulation  are  ex- 
plained; a  deck  listing  and  instructions  for  the 
program's  operation  are  included.  The  primary 
limitation  on  the  program's  applicability  to 
realistic  situations  is  that  the  atmosphere  is  as- 
sumed to  be  perfectly  stratified.  However,  the 
temperature  and  wind  profiles  may  be  arbitrari- 
ly specified.  Numerical  studies  carried  out  by 
the  program  show  some  discrepancies  with 
previous  computations  by  Harkrider  for  the 
case  of  an  atmosphere  without  winds.  These 
discrepancies  are  analyzed  and  shown  to  be 
due  to  different  formulations  of  the  source 
model  for  a  nuclear  explosion.  Other  numerical 
studies  explore  the  effects  of  various  at- 
mospheric parameters  on  the  waveforms.  In  the 
remainder  of  the  report,  two  alternate  theoreti- 
cal formulations  of  the  problem  are  described. 
The  first  of  these  is  based  on  the  neglect  of  the 
vertical  acceleration  term  in  the  equations  of 
hydrodynamics  and  allows  a  solution  by  Cag- 
niard's  integral  transform  technique.  The 
second  is  based  on  the  hypothesis  of  propaga- 
tion in  a  single  guided  mode  and  permits  a 
study  of  the  effects  of  departures  from  stratifi- 
cation on  the  waveforms.  (Author)

Wind  data  in  the  height  range  80  to  100  km  can 
be  obtained  with  a  multistatic  VHF  phase- 
coherent  pulse-doppler  meteor  radar  capable 
of  monitoring  a  volume  in  space  measuring  arr- 


poximately  50  km  x  50  km  horizontally,  and  20 
km  vertically.  An  eight-station  phase-coherent 
system  has  been  established  for  this  purpose 
near  Havana,  Illinois,  by  reworking  an  existing 
six-station,  incoherent,  pulse  meteor  radar 
operating  at  40.92  MHz.  A  4-Mw  transmitter  and 
eight  receiving  sites  dispersed  up  to  50  km 
away  from  the  transmitter  site  have  been  locked 
together  in  phase  within  a  few  parts  in  10  to  the 
10th  power  by  distributing  a  2.5  kHz  reference 
tone  via  commercial  telephone  lines.  The 
system  operates  satisfactorily  and  is  capable  of 
collecting  enough  range-doppler  samples  from 
meteor  trails  for  an  adequate  description  of  the 
wind  pattern  at  meteor  heights.  Wind  profiles 
have  been  obtained  by  processing  in  Cam- 
bridge with  a  CDC-6400  computer  the  mul- 
tichannel digital  tapes  recorded  in  Havana.  The 
method  can,  potentially,  be  used  for  real-time 
wind  measurements.  It  competes  favorably  with 
alternative  approaches  when  wind  measure- 
ments at  meteor  height  must  be  performed  with 
continuity  and  without  resorting  to  horizon-to- 
horizon  spatial  averaging.  (Author)

In  the  study  of  upper-atmosphere  winds  and 
densities,  radar  measurements  of  the  ionized 
trails  of  meteors  in  the  height  region  between 
80  and  110  km  have  proven  valuable.  In  the 
present  report,  this  measurement  technique  is 
compared  to  other  methods  and  its  advantages 
and  problems  are  outlined.  Considerations  for 
the  design  of  a  meteor-trail  radar  system  are 
presented.  The  desire  for  a  global  network  of 
meteor-trail  radar  stations,  which  would  aid 
significantly  in  the  study  of  synoptic  at- 
mospheric patterns,  calls  for  a  reliable,  simple, 
and  inexpensive  design.  Such  a  design,  real- 
ized at  Stanford  University  and  tested  in  opera- 
tion, is  described  in  detail.  Data  are  recorded

The  paper  describes  a  project  undertaken  by 
4th  Weather  Wing  to  produce  a  realistic  elec- 
tron density  profile  based  upon  parameters 
which  can  be  forecast  with  reasonable  accura- 
cy. The  ionospheric  electron  density  profile 
model  presented  in  this  paper  consists  of  the 
sum  of  three  Chapman  layers  (E,  F1,  F2).  Elec- 
tron  densities   in   the  topside   ionosphere  are 


controlled  by  complex  motions  rather  than  a 
production-loss  balance  and  cannot  be  suc- 
cessfully described  strictly  by  a  Chapman  layer. 
After  some  experimentation  a  best  fit  was  ob- 
tained by  simply  using  the  Chapman  equation 
for  the  topside  ionosphere,  but  computing  the 
electron  densities  by  using  a  variable  scale 
height  throughout  the  region.  The  program 
described  in  this  report  has  been  used  routinely 
for  eight  months  to  predict  profiles  for  radar 
refraction.  This  report  should  be  considered  in- 
terim as  improvements  in  accuracy  are  sure  to 
be  required  as  the  model  is  evaluated  for  dif- 
ferent purposes.  (Author)

Analyses  were  made  of  the  sea  surface  tem- 
peratures in  the  Gulf  of  Mexico  in  August  for 
the  four  years  1965  through  1968.  No  one  pat- 
tern was  found  to  predominate.  The  subsurface 
temperature  profiles  were  then  considered,  and 
a  rate  of  simulated  withdrawal  of  4000  calories 
of  heat  per  day  was  made,  until  there  was  no 
heat  in  excess  of  26C.  This  withdrawal 
represented  heat  removed  during  passage  of  a 
hurricane.  Difference  analyses  were  con- 
structed for  the  initial  sea  surface  temperature 
at  each  station  and  that  after  twenty-four  hours 
of  simulated  withdrawal.  The  differences 
ranged  from  less  than  one  degree  to  over  four 
degrees.  Again,  no  consistent  pattern  was 
found  but  generally  areas  of  high  concentra- 
tions of  heat  experienced  smaller  decreases. 
Actual  sea  surface  temperatures  collected  after 
two  hurricanes  were  then  analyzed  and  com- 
pared to  temperature  patterns  predicted  by  the 
computer  model.  Illustrations  of  the  relative 
availability  of  sensible  heat  energy  for  different 
sea  surface  temperatures  are  presented  and  a 
hypothesis  made  to  account  for  the  greater 
than  average  intensities  of  Hurricane  Betsy

Cold  Bay  and  Invercargill  form  an  approximate

at  these  two  stations  have  been  compared  and 
studied.  It  has  been  found  that  these  changes 
were  negatively  correlated  during  periods  of 
magnetic  quiet,  uncorrelated  during  weak  mag-

obtained  by  others,  show  that  the  delay 
between  the  time  of  maximum  obscuration  and 
the  time  of  minimum  content  varies  systemati-

The  motion  of  frontal  disturbances  in  the  at- 
mosphere is  studied  based  on  several  nonlinear 
models  proposed  by  Stoker.  In  the  first  model, 
the  air  is  considered  to  be  an  incompressible 
fluid  moving  over  a  plane  tangent  to  the  rotat- 
ing earth.  The  fluid  consists  of  two  layers  and 
the  density  in  each  layer  is  assumed  to  be  con- 
stant. The  hydrostatic  pressure  law  is  then  used 
to  reduce  this  to  a  two  space  dimensional 
model.  The  boundary  between  these  layers  is  a 
contact  discontinuity  and  so  instabilities  may 
occur  at  this  frontal  surface.  (Author)

Due  to  the  lack  of  measured  data  for  checking

was  initiated  at  Gulf  General  Atomic  (GGA)  for 
studying  the  atmospheric  transport  properties 
of  X-rays  by  using  liquid  nitrogen  to  simulate 
air.  Measurements  of  the  photon  spectrum  and 
angular  distribution  were  made  as  a  function  of 
source-detector  separation  distance  in  an 
infinite'  medium  of  liquid  nitrogen  provided  by 
a  large  cryogenic  dewar.  Radioactive  isotopes 
of  241Am,  141Ce,  and  203Hg  were  used  as 
sources  of  approximately  monoenergetic 
photons  with  energies  of  60  keV,  145  keV  and 
279  keV,  respectively.  A  20  cc  cm  Ge(Li)  detec- 
tor was  used  to  measure  photon  spectra  for 
energies  from  approximately  20  keV  to  the 
source  energy.  Measurements  were  made  for 
source  detector  distances  of  1-15  mfp  for  each

made  for  comparison  with  the  measurements

Integrated  data  from  a  vertical  pendulous  in-

hypsometer  in  an  airborne  gravimetric  installa-

assumed  constant  to  simplify  the  integration 
process.  The  aircraft-autopilot  short  period 
(about  0.044  Hz)  longitudinal  mode  dominates 
the  altitude  profile.  The  hypsomeier  recordings 
relative  to  the  integrated  accelerometer  data 
showed  lags  between  2  and  3  seconds,  and  am- 
plitude ratios  between  0.4  and  0.9.  A  backlash 
nonlinearity  of  3  feet  amplitude  would  explain 
the  varying  amplitude  ratio  but  only  part  of  the 
lag  (1  to  2  seconds).  The  auto-correlation  and 
crosscorrelation  functions  were  used  in  an  at- 
tempt to  examine  the  linear  behavior  of  the  hyp- 
someter; however,  the  spread  of  the  data  sug- 
gested that  the  nonlinearity  was  a  very  signifi-

described  in  this  paper  demonstrates  a  new  ap- 
proach to  objective  forecast  study  develop- 
ment. The  synoptic  situation  has  been  objec- 
tively integrated  into  the  initial  stratification  of 
climatological  data  and  therefore  permits  an 
objective  consideration  of  surface  and  700  mb 
map  patterns  as  the  initial  step  in  the  forecast 
procedure.  The  inclusion  of  climatologically-

The  technique  of  determining  the  distribution 
of  particle  sizes  in  a  cloud  by  measuring  the  in- 
tensity of  the  light  scattered  from  it  over  a  range 
of  angles  (sometimes  known  as  the  small  an- 
gles' method)  is  discussed  and  the  feasibility  of 
the  method  demonstrated  with  the  aid  of  digital 
computer  calculations.  The  effect  of  experi- 
mental errors  is  considered  and  a  detailed  ex- 
amination made  of  the  special  difficulties  as- 
sociated with  monodispersions,  in  which  all 
particles  are  of  the  same  size.  It  is  shown  that  in 
both  cases  modification  of  the  experimental 
data  by  means  of  suitable  weighting  functions 
yields  enhanced  reconstruction  of  the  original 
distribution  function.  The  limitations  of  the 
small  angles  method  are  discussed,  together 
with  the  data  requirements  which  should  be 
met  if  good  results  are  to  be  achieved.  (Author)

These  procedures,  designated  as  FLASH,  treat 
atmospheric  scattering  problems  for  plane- 
parallel,  point,  volume  and  spherical  surface 
sources.  The  FLASH  procedures  consider  the 
effect  of  Rayleigh  and  aerosol  scattering  and 
ozone,  water  vapor,  C02,  and  aerosol  particle 
absorption  on  the  transport  of  light.  The 
procedures  also  consider  the  changes  in 
polarization  that  occurs  at  each  scattering 
event.  The  input  formats  of  the  codes  allows 
one  to  describe  the  scattering  and  absorption 
properties  of  the  atmosphere  as  a  function  of 
altitude  Provisions  are  incorporated  for  treat- 
ing the  reflection  of  light  from  ground  and 
cloud  surfaces  with  an  albedo  method.  Also 
described  are  the  MIE-II  and  SHINE  procedures. 
The  MIE-II  procedure  uses  Mie  theory  to 
generate  aerosol  particle  scattering  and  ab- 
sorption coefficients  and  the  four  elements  of 
the  aerosol  phase  matrix  for  use  as  input  data

be  used  to  study  the  transport  of  visible  and  in-

These  procedures,  designated  as  TPART-I  and 
TPART-II,  treat  atmospheric  scattering 
problems  for  point  and  plane  parallel 
monochromatic  sources,  respectively.  The 
TPART  procedures  consider  the  effect  of

are  incorporated  for  treating  the  ground  sur- 
face with  an  albedo  method.  The  output  of  the 
TPART  procedures  gives  the  scattered  light  in- 
tensity at  each  receiver  position  as  a  function  of 
a  polar  and  azimuthal  angle  and  time.  The 
procedures  were  written  in  FORTRAN-IV  lan- 
guage for  both  the  CDC-6600  and  IBM  Direct 
Couple  Systems.  The  codes  have  been  verified 
through  comparisons  with  results  of  other  cal-

the  phase  and  amplitude  for  the  first  15  Fourier

cumulative  curves.  The  curves  were  influenced 
by  low  pressure  systems  which  passed  north  of 
the  area  of  4,  9,  15  and  19  July.  Wave  height  and

counterclockwise  around  the  low  pressure

dicted as  a  constant  times  the  derivative  of  the

Two  broad  classes  of  data  processing  pro- 
grams were  developed.  The  first  type  extracts 
and  prepares  for  transmissio  full-resolution 
subsets  of  the  original  ITOS  array.  The  data 
product  is  ideal  for  detailed  research  studies  or 
for  transmission  to  remote  locations  not 
equipped  to  directly  read  out  the  ITOS  sensor 
systems.  The  second  class  of  program  com- 
presses the  original  full  hemisphere  data  arrays 
by  averaging  or  by  selecting  maximum  or 
minimum  values.  The  new  array  is  then 
prepared  for  transmission.  This  data  product  is 
particularly  useful  for  input  to  global  environ- 
mental prediction  models.  Additional  support 
programs  were  developed  to  output  the  data 
products  described  above  onto  either  a  CRT  or 
printer  display.  These  displays  were  used  to 
perform  tradeoffs  between  the  data  preparation 
and  transmission  times  and  the  scientific  or 
meteorological  usefulness  of  the  various  data 
products.  It  was  found  that  a  factor  of  four 
redution  in  resolution  of  the  original  ITOS  array 
yields  a  data  product  which  is  transmittable  in 
an  acceptable  period  of  time  and  which  is  as 
useful  for  most  purposes  as  the  original  array.

A  machine  procedure,  designated  as  AURORA, 
was  developed  for  use  in  studies  of  the  effects 
of  non-local  energy  deposition  by  X-rays  in  the 
atmosphere.  The  AURORA  procedure  provides 
two  optional  methods  of  treating  the  slowing 
down  in  the  atmosphere  of  the  electrons 
produced  by  X-ray  collisions.  The  first  method 
assumes  that  the  earth's  magnetic  field  and  the 
ambient  electrostatic  field  have  no  effect  on  the 
path  of  the  electron.  The  second  method  as- 
sumes that  the  electrons  are  trapped  by  the 
earth's  magnetic  field  at  the  altitude  of  the  X- 
ray-electron  collision.  Modifications  were  made 
to  the  ZAP  procedure  to  provide  for  the  use  of 
source  angle,  source  energy,  and  path  length 
biasing.  The  PFLASH  procedure  was  modified 
to  allow  for  calculation  of  the  standard  devia- 
tion of  the  computed  results.  Biased  sampling 
schemes  for  picking  distances  between  colli- 
sions and  the  polar  and  azimuthal  angle  of  scat- 
tering were  incorporated  in  FLASH.  An  option 
was  incorporated  in  FLASH  and  DFLASH  for 
printing  their  results  as  a  function  of  the  re- 
tarded time.  A  study  was  performed  to  deter- 
mine the  effect  of  varying  the  size  of  the  air 
fluorescence  source  volumes  used  in  FLASH  on 
the  results  generated  by  FLASH.  A  method  of 
determining  the  size  of  the  volume  increments 
is  outlined.  (Author)

Failure  to  pass  these  checks  can  result  in  one  of 
two  actions:  one  or  two  parameters  may  be

Described  herein  is  a  TC  tracking  system  capa- 
ble of  real-time  visual  object  tracking.  The  total 
system  consists  of  low-light  TV  cameras  and 
communications  allowing  for  data  to  be  sent 
from  remote  sites  to  a  small  centrally  located 
computer.  The  position  of  the  object  that  the 
three  cameras  are  observing  is  calculated  by 
the  computer  and  transmitted  to  other  sites  for 
the  purpose  of  pointing'  other  equipment. 
Solutions  are  available  once  per  second.  This 
report  describes  the  actual  use  of  this  system 
during  the  SECEDE  2  test  series  and  some 
problems  encountered.  It  also  contains  enough

Using  a  steam  electric  generating  plant  as  the 
source,  an  investigation  was  made  into  the 
local  atmospheric  effect  of  a  large  industrial 
heat  and  moisture  source.  Data  collection  was 
attempted  with  ground-  and  helicopter-borne 
equipment  with  a  final  resort  to  the  helicopter 
when  the  ground  equipment  collection 
techniques  proved  unsatisfactory.  Cross  sec- 
tions of  temperature  and  moisture  were  drawn 
from  this  data  and  yielded  some  very  interesting

Analyses  are  made  for  15  layers  from  the  earth's 
surface  to  55,000  feet  MSL,  with  highest  vertical 
resolution  near  the  surface  (150  feet  depth  for

Summary  of  the  physical  bases  of  the  Mintz- 
Arakawa  two-level  atmospheric  model  and 
presentation  of  numerical  procedures  and 
computer  program  for  its  execution.  Discussion 
covers  the  physics  of  the  model,  with  particular 
attention  given  to  the  treatment  of  the  moisture 
and  heat  sources,  including  parameterization 
of  convective  processes,  cloudiness,  and  radia- 
tion. Numerical  approximations  and  finite-dif- 
ference equations  used  in  the  numerical  simu- 
lations are  also  given.  To  facilitate  the  use  of 
this  model,  a  complete  listing  of  the  code  as 
written  in  FORTRAN  language  is  given, 
together  with  a  description  of  all  constants  and 
parameters  used.  Also  included  are  a  dictionary 
of  FORTRAN  variables  and  a  dictionary  of  prin- 
cipal physical  features.  (Author)

The  direction  of  arrival  of  whistlers  and  related 
VLF  signals  has  been  measured  by  a  new 
technique.  This  technique  consists  of  applying 
an  already  existing  theory  (the  'four-parameter 
method')  to  data  collected  by  a  novel  measure- 
ment procedure.  Measurements  of  signals  in- 
duced in  orthogonal  loop  antennas  and  a  verti- 
cal monopole  located  at  a  single  site  provide 
the  necessary  data.  The  four-parameter  theory 
relates  the  loop  and  vertical  voltages,  taking 
into  account  both  amplitudes  and  phases  so 


that  polarization  error  may  be  eliminated.  The 
technique  can  be  shown  equal  or  superior  in 
accuracy  to  any  other  VLF  direction-finding 
scheme  in  current  use,  such  as  the  standard 
crossed-loops-and-goniometer  technique.

The  paper  supplements  4  WWg  Technical 
Paper  70-5,  'Predicting  Heavy  Snowfall  for 
Colorado  Springs  Based  on  Computer  Derived 
Synoptic  Map  Types'  (AD  718422).  The  success 
of  the  map  typing  technique  described  in 
4WWTP  70-5  depends  upon  the  size  of  the  area 
or  'window'  selected  for  typing.  In  the  Colorado 
Springs  snow  study  the  map  size  chosen 
covered  an  area  of  10  degrees  latitude  and  15 
degrees  longitude.  Since  this  is  approximately 
the  size  of  a  synoptic  scale  disturbance,  the 
map  types  which  were  developed  gave  a  good 
indication  of  the  general  circulation  pattern 
required  for  heavy  snow.  However,  where  heavy 
snowfall  is  influenced  by  the  local  area  flow  su- 
perimposed upon  the  broader  scale  features,  it 
is  possible  that  the  circulation  pattern  could 
correlate  highly  with  a  snow  type  and  still  not 
produce  the  forecast  snowfall.  The  paper 
describes  an  attempt  to  zero-in  on  the  small 
scale  circulation  by  correlating  only  one  corner 
of  the  large  window.  (Author)

The  generation  of  unstable  waves  in  the  mag-

waves  occurring  near  the  trapped  particles' 
gyrofrequencies.  Relativistic  modifications  to 
the  basic  theory  are  described.  The  evolution  of 
trapped  particles'  distribution  (diffusion)  is 
discussed,  and  the  non  linear  theories  of  wave 
propagation  and  growth  are  invoked  as  the 
means  whereby  the  evolution  of  the  distribution 
functions  can  be  studied.  It  is  pointed  out  that, 
because  of  difficulties  in  the  analytic  theories, 
computer  simulation  may  be  the  most  certain 
technique  for  investigating  effects  of  unstable 
waves  on  particles.  Some  particular  unsolved 
problems  are  indicated,  with  special  emphasis 
on  trapping  of  artificially  injected  electrons. 
The  development  of  a  computer  program  which

The  'ramp'  is  an  often  observed  feature  in  tem- 
perature fluctuations  during  unstable  at- 
mospheric conditions.  It  is  characterized  by  a 
gradual  increase  in  temperature  followed  by  a 
sudden  drop  to  an  ambient  level.  This  ramp 
clearly  distinguishes  temperature  signals  from 
other  turbulence  signals  such  as  velocity.  Three 
different  ramp-type  atmospheric  temperature 
fluctuations  and  their  derivatives  are  con- 
structed and  statistically  examined  for  the 
parameters  skewness  and  coefficient  of  excess. 
These  statistical  values  are  compared  with 
values  obtained  from  actual  signals.  (Author)

The  report  presents  a  program  for  numerically 
determining  mode  conversion  coefficients  and 
mode  sums  for  a  waveguide  which  is  in- 
homogeneous  along  the  direction  of  propaga- 
tion. The  program  allows  for  vertical  in- 
homogeneity  of  the  ionosphere  as  well  as  its 
anisotropy  due  to  the  geomagnetic  field.  The 
model  assumes  the  perturbation  has  no 
horizontal  space  dependence  perpendicular  to 
the  transmitter  receiver  line.  Mode  conversion 
coefficients  are  obtained  by  ignoring  reflec- 
tions associated  with  the  inhomogeneity  along 
the   direction    of   propagation.   The    latter  as- 


sumption greatly  simplifies  the  calculations  and 
appears  to  be  justified  for  a  broad  class  of 
horizontal  inhomogeneities.  However,  its  validi- 
ty under  severe  artificial  ionospheric 
disturbances  requires  further  study.  (Author)

A  physical  model  that  includes  experimental

processes  that  lead  to  emission  of  infrared 
radiation  has  been  implemented  in  a  computer 
program  that  computes  infrared  radiances  for 
an  earth's  limb  viewing  geometry.  The  nominal 
spectral  region  of  this  study  lies  between  five 
and  twenty-five  micrometers  and  emphasis  is 
placed  on  radiation  originating  at  altitudes 
between  70  and  500  km.  An  earlier  model  for 
the  transport  of  infrared  radiation  in  molecular 
bands  with  Doppler  line  shape,  accurate  only 
for  linear  molecules,  has  been  extended  to 
bands  of  polyatomic  molecules.  A  chemistry 
program  which  includes  the  effects  of  vertical 
transport  by  eddy  mixing  and  molecular  diffu- 
sion has  been  developed  to  make  possible  an 
estimate  of  diurnal  variation  in  the  abundances 
of  infrared  emitting  species.  (Author)

A  study  was  made  of  charged  particle  motion  in 
a  free-vortex  flow  field  to  determine  the 
parameters  affecting  particle  motion  and  to 
determine  the  extent  to  which  applied  electric 
fields  can  influence  the  particle  motion.  Four 
different  cases  were  investigated.  These  in- 
cluded first,  the  analysis  of  the  motion  of  an 
uncharged  particle  in  a  free-vortex;  second, 
analysis  of  the  motion  of  a  charged  particle  in  a 
viscous  medium  under  the  influence  of  an  ap- 
plied electrostatic  field;  third,  analysis  of 
charged  particle  motion  in  a  free-vortex  under 
the  influence  of  the  applied  electrostatic  field, 
assuming  the  particle  is  first  positively  and  then 
negatively  charged;  and  fourth,  analysis  of  the 
motion  of  two  charged  particles  in  a  free-vor- 
tex, accounting  for  field  effects  due  to  particle 
charge.  (Author)

A  two-dimensional  dynamical  model  is 
developed  for  the  specific  purpose  of  forecast- 
ing fog  for  time  periods  of  as  much  as  eight 
hours  on  a  local  scale  Time-dependent  winds 
are  generated  by  calculating  a  streamfunction 
from  a  model-produced  vorticity  field.  A  diurnal 
variation  at  the  surface  is  simulated  by 
sinusoidally  varying  boundary  conditions  on 
temperature.  Surface  terrain  effects  can  be  in- 


corporated through  boundary  conditions  to 
provide  a  means  of  adapting  the  method  to  a 
particular  location.  Only  grosser  features  of 
microphysical  processes  have  been  incor- 
porated, and  the  values  of  the  wind  forecasts 
are  limited  by  the  inability  of  a  two-dimensional 
model  in  the  X-2  plane  to  include  synoptic- 
scale  variations.  Fine-scale  data  are  required 
for  the  model,  which  is  thereby  well-suited  to 
provide  forecast  support  for  such  activities  as 
fog  modification  experiments.  (Author)

dicted on  a  routine  basis  by  the  National 
Weather  Service,  NOAA,  and  it  was  felt  that  if 
such  a  procedure  could  be  developed,  it  would 
be  possible  to  provide  estimates  of  beach  ero- 
sion or  deposition  as  part  of  routine  weather 
forecasts  whenever  storms  threatened.  It  was 
also  hoped  that  it  might  be  possible  to  make 
estimates  of  shoreline  erosion  during  previous 
years  by  using  historical  storm  data  in  the  pre-

An  apparatus  was  designed  and  constructed  to 
determine  the  effect  of  atmospheric  turbulence 
on  the  modulation  transfer  function  (MTF)  of 
the  atmosphere.  A  reflecting  telescope  and  reti- 
cle system  provided  optical  information  in  the 
visible  region  to  a  silicon  photodiode  detector 
which  was  responsive  from  .35  micron  to  1.1 
microns.  The  output  of  the  detector  was 
processed  to  measure  irradiance  modulation 
from  a  target  of  known  spatial  frequency.  The 
modulation  transfer  function  of  the  atmospher- 
ic transmission  medium  and  the  optical  system 
was  measured  under  calm  conditions  and  con- 
ditions of  turbulence  on  a  270  meter  round  trip 
path  through  a  building  corridor.  The  optical 
apparatus  described  was  capable  of  detecting, 
in  the  visible  range,  the  degrading  effect  of  tur- 
bulence on  MTF.  All  reflective  optics  were  used 
so  that  the  visual  through  10  micrometers  range 
can  be  covered  with  use  of  different  detectors.

The  work  is  an  application  of  adaptive  estima- 
tion to  temperature  forecasting.  It  is  presented 
as  a  feasibility  study  demonstrating  the  efficacy 
of  the  adaptive  approach.  The  local  station  tem- 
perature forecasting  problem  is  chosen  to 
focus  the  discussion  on  the  efficiency  of  the  fil- 
tering algorithm  by  using  only  surface  level  sin- 
gle geographic  location  data.  A  diagnostic 
study  is  made  to  ascertain  the  appropriate 
statistical  properties  of  the  weather  data  for  al- 
gorithm selection.  A  phenomenalistic  approach 
is  taken  since  no  differential  equation  or 
complete  quantitative  description  exists  to 
describe  the  temperature  process.  The  Lainiotis 
Filter  is  chosen  for  model  identification  and 
classification  as  well  as  prediction  results.  The 
Lainiotis  Filter,  given  in  the  Partition  Theorem, 
provides  an  efficient,  powerful  tool  in  the  appli- 
cation of  adaptive  estimation  techniques.  The 
feasibility  of  the  adaptive  approach  is 
established  with  comparative  results  with  previ- 
ous objective  forecast  methods  while  greatly 
reducing  the  amount  and  variety  of  required 
input  data.  (Author)

Programs  were  compiled  to  compare  experi- 
mental data  with  mathematical  models  with 
respect  to  magnetic  activity.  Micropulsations 
were  investigated  and  programs  were  written  to 
compute  the  eigenperiod  and  modulus  of 
decay,  so  the  predicted  results  could  be  com- 
pared with  experimental  observations.  This  was 
a  particularly  difficult  problem,  because  the 
dispersion  relationship  was  a  complex  trans- 
cendental equation,  and  required  a  2-part  fit. 
The  complex  function  was  mermorphic  with 
respect  to  its  complex  arguments,  and  so  the 
Cauchy-Riemann  conditions  were  applicable. 
The  secular  equation  was  expanded  in  a  Taylor 
Series,  and  then  the  equation  was  cast  in  a  form 
immediately  amenable  to  the  numerical  analy- 
sis. The  programs  were  written  and  can  now  be 
easily  reformated,  suitable  for  production  basis

An  instrument  was  designed  and  fabricated  for 
real-time  determination  of  the  auroral  electrojet 
current,  velocity,  and  location  in  order  to  assist 
in  selection  of  the  optimum  launch  time  for 
rockets  used  to  study  auroral  phenomena  as- 
sociated with  substorms.  The  instrument  incor- 
porates a  small  digital  computer  to  calculate 
these  quantities  by  use  of  inputs  from  up  to  five 
3-axis  magnetometers.  During  two  on-site  ap- 
plications at  Churchill  Research  Range  data 
from  3-axis  magnetometers  situated  at  two  dif- 
ferent locations  on  a  north-south  line  from 
Churchill  were  used.  During  the  two  substorms 
studied,  the  jet  was  located  near  140  km  al- 
titude and  the  intensity  of  each  was  as  high  as 
0.5  megaamps.  In  one  case,  both  stations  gave 
results  similar  to  the  two  station  fit,  so  the  jet 
was  well  approximated  by  a  line  current.  In  the 
second  case,  the  data  suggest  that  the  current 
was  either  a  sheet  current  or  a  group  of  fila- 
ments. Recommendations  are  made  for  in- 
creasing the  data  processing  capability  of  the 
instrument  in  order  to  handle  such  realistic 
electrojet  configurations  in  real-time.  (Author)

A  detailed  comparison  of  atmospheric  refrac-

comparison  shows  that  the  data  correction  pro-

better  agreement  when  all  are  given  the  same 
refractive  index  profile  than  they  do  when  they 
are  allowed  to  use  that  surface  value  to  deter- 
mine the  profile  by  their  own  internal  methods. 
A  profile  with  a  strong  super-refractive  layer 
was  also  used  in  comparing  the  programs. 
Widely  differing  refractive  bending  effects,  is 
less  than  10  feet.  The  report  shows  that  the  nu- 
merical methods  of  the  various  refraction  cor- 
rection programs  produce  similar  results  with 
similar    input    data.    It    also    shows    that    care

one  range  and  processed  at  another  is  refrac- 
tion corrected  with  atmospheric  data  for  the 
range  at  which  the  data  was  taken.  Numerical 
methods  of  refraction  correction  are  similar  at 
the  various  ranges  but  local  atmospheres  are

An  accurate  geomagnetic-field  model,  consist- 
ing of  the  dipole  plus  seven  higher-order  har- 
monics in  dipolar  coordinates,  is  incorporated 
into  a  computer  program  for  three-dimensional 
ray  tracing.  Three  options  of  using  magnetic- 
field  models  are  provided:  (1)  using  accurate 
field  in  computing  both  the  ray  trajectory  and 
the  propagation -aspect  angle  between  the 
geomagnetic-field  vector  and  the  wave-normal 
vector  associated  with  each  point  along  the  ray; 
(2)  using  the  dipole  field  for  computing  rays  but 
using  the  accurate  field  for  computing  aspect 
angles;  (3)  using  the  dipole  field  for  both  the 
rays  and  aspect  angles.  Comparisons  are  made 
among  the  results  computed,  using  the  three 
options,  in  the  HF  band  for  a  nighttime  polar 
ionosphere  and  for  a  noontime  equatorial  iono- 
sphere.   Typical     differences    of    few    to    ten

degrees  occur  in  the  aspect  angle,  for  aspect 
angles  near  90  degrees  —  the  value  under  which 
geomagnetic-field-aligned  ionization,  if 
present,  would  give  rise  to  maximum 
backscatter  of  HF  waves  and  thus  cause  clutter 
in  Over-the-Horizon  radars.  (Author)

nonlinear  effects,  dispersion,  and  wave  distor-

the  prediction  of  acoustic  gravity  wave  genera- 
tion by  rising  and  oscillating  fireballs.  Numeri- 
cal studies  are  reviewed  which  indicate  the  de- 
pendence of  far  field  waveforms  on  energy  yield 
and  burst  height.  Implications  of  the  Lamb  edge 
mode  theory  include  a  new  method  for  estimat-

Application  of  the  photochemical  computer 
code,  developed  by  Keneshea,  to  the  D-region 
is  considered.  Only  the  use  of  high  speed  com- 
puters can  provide  the  required  analysis  under 
such  transient  conditions  as  twilight.  Even  for 
equilibrium  conditions,  the  performance  of  the 
calculation  by  a  computer  is  necessary  for  a 
complete  description  of  the  D-region  since  a 
very  large  number  of  processes  is  involved.  The 
photochemical  code  presently  includes  195 
reactions  for  the  40  species  considered.  Certain 
constituents  like  NO,  also  O  and  03  at  the 
higher  altitudes,  must  be  inserted  as  constants 
since  transport  processes  are  required  for  the 
proper  description  of  their  atmospheric 
profiles.  The  results  obtained  from  application 
of  the  code  to  the  D-region  during  a  PCA  event

A  numerical  model  was  developed  for  the  simu- 
lation of  fog  and  stratus  in  the  marine  planetary 
boundary  layer.  Physical  processes  described 
by  the  model  are  eddy  diffusion,  horizontal  ad- 
vection,  fog  droplet  settling,  infrared  radiation 
and  change  of  thermodynamic  state  of  moist 
air.  Results  of  the  computations  show  the  rela- 
tive importance  of  the  processes  considered  in 
the  development  of  stratiform  clouds  in  the 
planetary  boundary  layer.  Among  the  most  im- 
portant factors  governing  the  extent  of  fog  are 
the  magnitudes  of  horizontal  advection  of  heat 
and  infrared  radiation  by  cloud  and  water 
vapor.  Comparisons  of  the  computational 
results  with  existing  observations  show  that  the 
formation  process  has  been  adequately 
described.  Additionally,  it  was  shown  that  oc- 
currence of  fog  over  the  ocean  could  result  in 
air  temperature  colder  than  that  of  the  sea  sur- 
face, caused  by  radiation  heat  loss  from  the 
cloud  top.  Results  indicate  that  a  practical  fog 
forecast  model  is  feasible  with  certain  refine- 
ments, such  as  inclusion  of  the  effects  of  haze 
on  the  infrared  radiation  balance,  inversion 
strength  on  the  growth  of  the  mixing  layer 
depth,  and  insolation.  (Author)

The  report  documents  the  computer  programs 
of  the  Bent  Ionospheric  Model  and  briefly 
describes  the  development  of  the  model.  The 
FORTRAN  Program  is  designed  for  general  use 
and  can  generate  ionospheric  data  on  a  world- 
wide basis  for  any  past  or  future  date.  For  a 
given  condition  consisting  of  station,  satellite 
and  time  information,  the  electron  density  ver- 
sus height  profile  is  computed  from  which 
range,  range  rate,  and  angular  refraction  cor- 
rections as  well  as  vertical  and  angular  total 
electron  content  are  obtained.  The  model  has 
the  additional  capability  of  improving  its  pre- 
dictions by  updating  with  actual  ionospheric 
observations.  Considerable  tests  in  the  past 
have  proved  this  empirical  model  highly  suc- 
cessful. Also  included  in  the  documentation  is 
an  alternate  version  of  the  ionospheric  program 
to  be  used  when  stringent  space  and  time 
requirements  are  imposed  by  the  operating 
system.  However,  several  options  of  the  stan- 
dard program  are  not  incorporated  and  the  ac- 
curacy of  the  results  is  somewhat  reduced.

The  author  uses  automated  symbolic  manipula-

prognostic  equations  of  meteorology.  These 
equations  are  treated  in  the  form  that  would 
arise  by  means  of  modal  analysis  and  trunca- 
tion. Consequently  the  equations  take  the  form 
of  coupled  non-linear  first-order  ordinary  dif-

tions may  be  very  large  if  many  modes  are  in-

in  conjunction  with  an  extensive  program  to  in- 
vestigate climate  prediction  and  modification. 
Also  of  interest  is  the  long  term  behavior  of  the

A  summary  of  results  is  made  in  this  Final  Re-

Hardward  Developments;  (4)  Software  Develop- 
ments; and  (5)  Results  of  a  Cumulus  Cloud 
Magnetic  Field  Survey.  It  is  concluded  that  VLF 
sferics  has  no  intrinsic  predictive  content.  How- 
ever, sferic  behavior  is  closely  correlated  with 
cloud  development  and  vigor  and  thus  has  very 
high  indicative  content.  A  method  for  examin- 
ing the  electric  current  motions  within  a  cumu- 
lus cloud  by  sensing  the  resulting  magnetic

The  document  consists  of  five  scientific  re-

described  which  simulate  ionospheric  currents 
responsible  for  quiet-day  ground  magnetic 
variations  at  middle  and  equatorial  geomag- 
netic latitudes.  The  program  enables  us  to 
deduce  the  large-scale  electrostatic  fields 
generated  by  dynamo  actions  in  the  iono- 
sphere. The  second  report  describes  a  com- 
puter program  for  mapping  of  the  ground  mag- 
netic potential  pattern  on  any  given  day,  either 
quiet  or  disturbed.  The  other  reports  are 
reprints  of  articles  which  have  been  either  fully

A  system  to  measure  laser  beam  wander  and 
beam  spread  in  the  atmosphere  over  the  ocean 
has  been  designed,  constructed,  and  tested. 
The  apparatus  employed  a  high  resolution 
scanning  telescope  with  a  potential  for  use  in  a 
broad  range  of  visual  and  infra-red 
wavelengths,  and  with  the  ability  to  measure 
beam  wander  and  beam  spread  variations  on 
the  order  of  a  few  microradians  in  angle  of  in- 
cidence. Three  successful  trials  with  a  propaga- 
tion path  over  the  southern  end  of  Monterey

how  this  linear  correlation  coefficient  formula 
behaves  when  it  is  used  to  correlate  surface 
weather  map  patterns  that  are  similarily  con- 
figured but  differ  in  respect  to  their  direction  of 
flow  patterns,  their  pressure  gradients  and  their

clarify  the  relationship  between  similar  map 
types,  their  pressure  gradients  and  their  degree

The  principal  concern  of  this  thesis  is  to 
analyze  emission  control  strategies  which  de- 
pend upon  meteorological  conditions.  A  me- 
terological  model  is  developed  to  relate  source 
emissions  with  average  concentration  of  a  pol- 
lutant in  a  region  under  different  meteorologi- 
cal conditions.  The  problem  of  determining  op- 
timal dynamic  controls  for  S02  emissions  at 
fossil-fueled  power  stations  is  treated  by  con- 
structing a  linear  programming  model.  This 
model  is  extended  to  encompass  seasonal  con- 
trol of  sources  which  are  not  amenable  to  more 
frequent  controls.  Another  extension  is  con- 
structed to  analyze  the  effects  of  errors  in 
meteorological  forecasts.  The  various  models 
are  applied  to  the  Metropolitan  Boston  Air  Pol- 
lution Control  District.  The  impact  of  dynamic 
emission  controls  on  new  site  selection  for  fos- 
sil-fueled power  stations  is  examined.  A 
stochastic  linear  programming  formulation  is 
developed  and  an  algorithm  is  designed  to 
solve  the  stochastic  linear  programming 
problem.  (Modified  author  abstract)

can  predict  the  chemistry  and  photochemistry 
of  the  atmosphere  in  the  regions  of  the  upper

dinal changes,  the  chemical  reaction  set  can  be 
quickly  changed,  and  laboratory  problems  can 
be  treated  by  turning  off  the  solar  flux  routines, 
the  numerical  integration  method  is  new,  rapid, 
and  inherently  conserves  mass.  A  stiff  equation 
technique  is  used  to  increase  the  time  incre- 
ment during  steady-state  conditions  The  cur- 
rent model  can  be  used  to  predict  events  that 
can  be  correlated  with  rocket  observations,  or

The  suitability  of  shipboard  profile  measure- 
ments of  mean  temperature,  mean  humidity 
and  mean  wind  over  the  open  ocean  is  ex- 
amined on  the  basis  of  six  hours  and  20 
minutes  of  simultaneous  profile  measurements 
made  from  the  R/V  Acania  on  20-21  September 
1973  near  San  Nicolas  Island,  California.  Com- 
parisons of  the  profiles  obtained  from  the  ship- 
board measurements,  as  well  as  the 
meteorological  parameters  derived  from  those 
profiles  are  made  with  results  obtained  from 
more  stable  platforms.  Parameters  examined 
include  the  Richardson  number,  the  friction 
velocity,  the  drag  coefficient  and  the  roughness 
length.  The  results  indicate  that  a  ship  can  be  a 
suitable  platform  for  measuring  profiles.

Initialization  of  a  five-level  global  baroclinic

real  data.  Experiments  were  conducted  using  a 
Robert  (1965)  time  frequency  filter,  Euler

tialization scheme  to  determine  the  effect  of 
each  on  the  generation  of  inertial-gravity  waves 
resulting  from  an  improper  balance  between  in- 
itial mass  and  wind  fields.  In  addition,  a  global 
sigma-surface  linear  balance  equation  solution 
was  examined  for  the  purpose  of  determining 
initial  winds.  Although  all  forecast  fields  were 
meteorological,  certain  undesirable  features

One  process  to  explain  natural  ice  pellets  in  the 
atmosphere  is  the  heterogeneous  freezing  of 
large  cloud  drops.  These  experiments  show 
that  this  process  is  of  little  importance.  Drops  of 
about  180  micrometer  diameter  which  fell 
through  high  concentrations  of  aerosol 
nucleating  particles  showed  consistantly  very 
low  percentages  of  freezes.  From  the  informa- 
tion gathered  a  temperature  threshold  for  lead 
iodide  and  phloroglucionol  of  -10C.  and  -6C 
respectively  was  determined.  Also  a  depen- 
dence on  the  relative  humidity  of  the  air  in  the 
vicinity  of  particle  collection  was  observed.  This 
gave  rise  to  relative  humidity  thresholds  of  65% 
for  lead  iodide  and  75%  for  phloroglucionol. 
The  nucleating  ability  of  airborne  ice  crystals 
was  experimentally  tested  and  found  to  be 
much  lower  than  expected.  This  difference  is 
attributed  to  a  collection  efficiency  for  drops 
collecting  non-spherical  ice  crystals,  which  is 
much  lower  than  a  calculated  collection  assum- 
ing the  ice  to  be  spherical.  (Author)

A  balloon-borne  submicron  aerosol  counter 
developed  under  previous  Air  Force  contracts 
was  successfully  flown  on  three  stratospheric 
balloon  experiments  over  Holloman  AFB,  New 
Mexico  in  May  of  1973.  The  results  indicate  that 
particulate  matter  at  higher  levels  is  charac- 
terized by  markedly  different  scattering 
parameters  than  is  the  case  at  lower  levels.  This 
effect  is  manifested  in  the  form  of  exceedingly 
sharp  cut-offs  in  the  size  distribution  at  about 
0.4  micrometer  diameter,  which  is  only  ob- 
served above  23  km.  The  extent  to  which  this 
sharp  cut-off  is  attributable  either  to  nonspheri- 
cal  particles  or  to  index  of  refraction  uncertain- 
ties rather  than  to  the  actual  size  distribution,  is 
a  matter  of  conjecture  Recommendations  for 
equipment  modifications  tending  to  eliminate 
these  ambiguities,  are  discussed.  Also 
described  here  are  the  several  hardware  and 
software  modifications  incorporated  in  the 
system  under  the  present  contract  in  prepara- 
tion for  these  flights.  (Author)

analysis. 

An  empirical  density  model  based  on  drag 
analyses  of  25  low-perigee  satellites  is 
developed  for  use  in  predicting  low-altitude 
satellite  ephemerides.  A  stepwise  multiple 
regression  analysis  is  performed  with  density  at 
145  km  as  the  dependent  variable,  and  a 
number  of  independent  variables  chosen  to 
represent  variations  with  solar  cycle,  geomag- 
netic activity,  geomagnetic  latitude,  season, 
day  of  the  year,  and  time  of  day.  Densities 
between  120  and  500  km  are  determined  from 
the  hydrostatic  law  in  a  simple  (but  physically 
realistic)  analytic  form.  Comparison  of  our 
model  with  the  1971  Jacchia  model  shows  them 
both  to  give  very  similar  variations,  differing 
mostly  with  respect  to  solar  activity  and 
geomagnetic  latitude.  The  main  virtue  of  our 
model  is  that  it  is  represented  in  an  extremely 
simple  analytic  form,  and  therefore  ideally 
suited  for  implementation  in  an  operational 
system.  (Author)

The  study  traces  the  development  of  a  weather 
model  based  on  a  real  transition  Semi-Markov 
process.  The  data  consisted  of  eighteen  years 
of  taped  hourly  weather  observations  from  Bit- 
burg  Air  Base,  Germany.  Maximum  likelihood 
estimators  were  used  to  construct  the  basic 
parameters  of  the  model  from  the  taped  data. 
The  results  consist  of  weather  models  for  each 
season.  The  model  for  the  winter  season  was 
used  to  develop  both  short  and  long-term 
weather  statistics.  The  results  confirmed  that 
the  Semi-Markov  process  may  be  used  to 
develop  a  weather  model  that  requires  few  as- 
sumptions, is  small  in  size,  independent  of  geo- 
graphic location,  and  is  distribution  free.

The  final  report  describes  an  effort,  under  the 
Simulation  Program,  to  understand  infrared 
backgrounds  in  an  auorally-disturbed  environ- 
ment. A  large  part  of  this  effort  has  been 
devoted  to  the  development  and  use  of  a  code, 
called  ARCTIC,  that  is  suitable  for  the  study  and 
analysis  of  auroral  data.  The  code  inputs  a  flux 
spectrum  of  primary  electrons,  incident  on  or  in 
the  atmosphere,  with  a  specified  magnetic  dip 
angle  and  a  given  initial  pitch  angle  distribu- 
tion, and  computes  the  detailed  energy  deposi- 
tion and  partition  in  the  atmosphere.  Scattering 
of  the  primary  electrons  is  provided  for  in  the 
deposition  subroutine  by  two  options:  one,  that 
allows  for  the  full  effects  of  range  variance, 
gives  excellent  agreement  with  observations  in 
nitrogen;  the  other,  that  is  considerably  more 
economical  to  use,  assumes  mean  scattering 
only.  (Modified  author  abstract)

Both  tangent  and  buried  burst  scenarios  are 
treated.  The  calculations  are  based  on  the 
AFWL  CHEMP  code  for  self-consistent  calcula- 
tions of  radiated  EMP,  modified  by  the  inclu- 
sion of  a  swarm  treatment  of  secondary  and 
ionospheric  electrons.  The  region  of  applica- 
bility of  this  swarm  treatment  has  been  deter- 
mined by  a  separate  Monte  Carlo  calculation. 
By  carrying  the  calculations  all  the  way  from  the

are  able  to  account  fully  for  the  D  region  heat-

There  is  much  disagreement  as  to  (1)  what 
causes  clear  air  turbulence  (turbulence  which 
is  not  in  or  near  convective  clouds  and  is  above 
15.000  feet  in  altitude)  and  (2)  which 
meteorological  parameters  can  be  used  to  de- 
tect and  forecast  its  occurrence  The  approach 
to  this  problem  has  been  to  relate  not  one 
parameter  to  clear  air  turbulence  but  various 
parameters  By  summing  these  parameters 
areas  can  be  defined  where  there  is  a  high 
probability  of  encountering  clear  air  turbu- 
lence. Each  parameter  has  been  based  on  a 
statistical  study  which  found  a  relationship  with 
clear  air  turbulence  The  parameters  used  were 
horizontal  and  vertical  shear,  curvature,  kinetic 
energy  and  their  derivatives.  The  numerical 
forecasting  program  proposed  here  can  be  ex- 
tended to  the  stratosphere  when  more  reliable

based  on  data  obtained  from  navigational  satel- 
lites. Thus,  the  only  instrumentation  required  by 
the  method  is  a  receiver  for  the  signals  from  the 
satellite,  and  a  computer.  A  principal  purpose 
for  determining  atmospheric  refraction  charac- 
teristics would  be  the  location  of  possible  duct- 
ing and  trapping  layers.  An  estimate  is  given  for 
the  degree  of  accuracy  that  the  method 
requires  of  the  data  received  from  the  satellite 
to  accomplish  this  purpose.  (Author)

This  report  documents  all  aspects  of  the 
analyses  of  long-range  regulations  for  control 
of  SO  sub  2  and  particulates  in  the  Chicago 
Metropolitan  Air  Quality  Control  Region: 
dispersion  model,  strategy  model,  emission  in- 
ventory, present  regional  air  quality,  a  compen- 
dium of  possible  control  regulations  for  SO  sub 
2  and  particulates,  and  extensive  calculational 
results.  The  application  of  the  Air  Quality  Dis- 
play Model  (AQDM),  a  computer  program 
designed  to  estimate  the  spacial  distribution  of 
sulfur  dioxide  and  particulate  concentrations, 
is  described.  The  AQDM,  which  is  derived  from 
the  Martin-Tikvart  (1968)  diffusion  model,  is 
based  on  the  Gaussian-diffusion  equation 
which  describes  the  spreading,  or  diffusing,  of 
a  plume  as  it  is  transported  downwind  from  an 
elevated,  continuously  emitting  point  source. 
The  model  is  utilized  here  to  compute  annual, 
arithmetic-,  and  geometric-mean  ground-level 
pollutant  concentrations  resulting  from 
specified  point  and  area  sources.  The  model 
calculates  the  effects  of  each  source  on  each 
receptor  for  the  observed  combinations  of  wind 
direction,  wind  speed,  and  stability  class.  The 
relative  frequency  of  occurrence  for  each  com- 
bination is  then  included  as  a  factor,  and  the 
resulting  data  are  summed  for  each  receptor 
over  all  combinations  and  all  sources.  (ERA

The  computer  program  ATMOSPHERE  permits 
prediction  of  the  diffusion  of  exhaust  gases  ex- 
pelled by  high  industrial  chimneys  into  the  at- 
mospheric boundary  layer.  In  addition,  the  pro- 
gram can  be  used  to  compute  the  diffusion  of 
cooling  or  sewage  fluids  in  lakes  and  oceans. 
The  assumptions  on  which  the  model  is  based 
limit  the  application  to  continuous  flows 
characterized  by  axial  symmetry  introduced 
into  approximately  infinitely  extended  flows 
free  of  return  flows  and  shear.  The  simulation 
model  can  predict  the  diffusion  of  bouyant  jets 
even  when  the  free  stream  contains  tempera- 
ture and  concentration  gradients  and  when  the 
density  differences  between  the  jet  and  ambient 
fluid  are  not  negligibly  low.  The  effects  of 
background  turbulence  and  possible  inversion 
layers  on  the  diffusion  process  are  taken  into 
consideration.  The  predictions  of  the  model  are 
compared  with  experimental  data.  (ERA  cita-

Decision  analysis  techniques,  using  Bayes

analyzing  Florida  cumulus  seeding  experi-

evaluate  the  seeding  effect  upon  rainfall,  it  is 
necessary  to  know  the  distribution  and  its  suffi- 
cient statistics  for  both  seeded  and  natural  rain. 
Lacking  this  knowledge,  several  assumptions 
are  made  for  use  in  the  evolution  of  the  Baye- 
sian approach.  A  procedure  is  outlined  showing 
how  decision  analyses  may  be  used  with 
forthcoming  experiments.  These  methods  are 
likely  to  have  rather  wide  application  in  the 
analysis  of  meteorological  experiments.

Time-dependent  moist  columnar  convection  is 
numerically  modelled  as  an  extension  of  Priest- 
ley's 1953  study  of  buoyant  dry  elements  in  a 
turbulent  environment.  The  distinctive  velocity 
regimes  characteristic  of  the  model  and  akin  to 
those  discussed  by  Priestly,  may  be  classified  in 
terms  of  environmental  lapse  rate,  moisture 
content,  and  the  size  and  amplitude  of  initiating 
and  following  disturbance.  Several  types  of 
conditions  develop  in  conditionally  unstable 
cases:  a  strong  steady  updraft  may  develop 
without  precipitation  beneath  but  with 
precipitation  outside  an  implied  area  of  strong 
updraft,  when  there  is  a  strong  starting  pertur- 
bation, small  mixing  rate,  an  elevated  conden- 
sation level,  and  a  steep  lapse  rate.  The  model 
suggests  that  a  critical  horizontal  size  and  criti- 
cal perturbation  buoyancy  must  be  exceeded  in 
nature  if  sustained  moist  convection  is  to  result 
in  any  given  conditionally  unstable  lapse  rate 
and  moisture  condition  (Author)

Two  separate  methods  (based  on  dynamics)  to 
estimate  or  forecast  the  surge  are  developed. 
The  first  method  in  which  precomputed  nomo- 
grams are  used  is  designed  only  to  arrive  at  a 
peak  surge  value.  Arguments  for  the  nomo- 
grams are  simple  meteorological  parameters.  In 
the  second  method,  a  dynamic  model  is  used  to 
compute  surges  along  an  entire  coastline. 
Computations  are  done  by  an  electronic  com- 
puter; surface  meteorological  parameters  are 
used  as  input  to  the  operational  program. 
Qualitative  explanations  for  the  surge 
phenomena  are  interspersed  throughout  part  I. 
The  relative  importance  of  various  meteorologi-

tion. The  effects  of  instrument  type,  numbers, 
locations,  and  sampling  intervals  on  the  accu-

ever, due  to  uncertainties  associated  with  the

A  field  study  to  evaluate  the  technique

The  HURRAN  (hurricane  analog)  technique,  a 
fully  computerized  objective  forecast  aid  mak- 
ing use  of  past  tracks  in  forecasting  hurricane 
motion,  was  developed  prior  to  the  1969  hur- 
ricane season.  Encouraging  operational  results 
during  the  1969  and  1970  hurricane  seasons 
suggested  further  evaluation  of  the  technique. 
To  this  end,  HURRAN  computations  were  made 
for  approximately  1,000  forecast  situations. 
Results  are  stratified  according  to  initial 
direction  and  speed  of  movement  of  the  sample 
storms  and  the  number  of  analogs  selected. 
The  utility  of  the  technique  is  discussed,  and 
the  importance  of  position  accuracy  at  forecast

time  is  demonstrated.  Initial  indications  of  the 
value  of  the  technique  are  substantiated.

for  developing  operational  river  forecasts 
based  on  the  use  of  a  continuous  conceptual 
model,  from  the  initial  processing  of  basin  data

An  objective  map  analysis  technique  applicable 
to  quasi-steady,  translating  atmospheric  circu- 
lations is  developed  from  the  mathematical 
premise  that  distributions  of  meteorological 
variables  can  be  represented  by  an  infinite  sum 
of  independent,  harmonic  waves.  In  addition  to 
the  usual  space-weighting  of  simultaneous  ob- 
servations to  obtain  interpolated  values  at  regu- 
larly arrayed  grid  points,  the  scheme  uses 
asynoptic  observations  by  positioning  them 
relative  to  a  moving  disturbance  and  weighing 
them  according  to  both  space  and  time.  Analy- 
sis response  for  several  choices  of  the  arbitrary 
parameters  is  tested  on  simple  analytically 
determined  distributions  and  on  selected 
meteorological  observations  during  the 
passage  of  three  thunderstorms  over  the  Na- 
tional Severe  Storms  Laboratory  mesonetwork 
of  surface  and  upper  air  stations  in  central 
Oklahoma.  (Modified  author  abstract)

The  gamma  distribution  function  may  be  used 
as  a  model  for  many  sets  of  data.  The  electronic 
computer  program  in  the  Formula  Translator 
(FORTRAN)  4  for  this  function  here  provides  the 
analytic  solution  to  a  set  of  data,  gives  the 
probabilities  of  exceeding  or  not  exceeding  ar- 
bitrary amounts,  and  indicates  the  amounts  ex- 
ceeded or  not  exceeded  for  arbitrary  probabili- 
ties. The  developed  gamma  probability  plotting 
paper  serves  also  for  the  special  cases  of  the 
chi-squared,  the  exponential,  and  the  Poisson 
distribution  functions.  Estimates  of  the  scale 
and  shape  parameters  permit  construction  of 
the  graph.  The  graph  paper  may  be  used  to  esti- 
mate the  scale  and  shape  parameters.  The  pro- 
gram, in  its  general  form,  permits  a  maximum  of 
52  entries,  which  will  suffice  for  those  dealing 
with  weekly  data  through  the  year.  In  addition, 
in  precipitation  studies,  the  user  has  the  option 
to  compute  in  one  pass  of  the  data  the  two  du- 
ration and  three  duration  period  distributions. 
These  computations  are  done  without  program 
change  but  by  appropriate  changes  in  the  con- 
trol cards.  This  feature  is  not  limited  to  the 
study  of  precipitation  data.  An  option  permits 
the  computation  of  the  required  probabilities 
and  inverses  when  only  the  scale  and  shape 
parameters  are  given.  (Modified  author  ab-

An  operational  computer  program  has  been  ex- 
panded to  accommodate  storms  with  general- 
ized motions  of  not  too  great  complexity.  Ex- 
amples are  storms  that  move  alongshore, 
recurve,  remain  stationary,  accelerate,  and 
landfall  (exit).  Also,  storm  strength  and  size  are 
allowed  to  vary  in  a  continuous  monotonic 
manner  with  time.  Surges  generated  by  these 
generalized  storms  are  complicated  in  space 
and  time,  and  they  can  occur  on  an  extensive 
coastline  (hundreds  of  miles).  Five  track  posi- 
tions (spaced  at  6-hr  increments  on  the  storm 
path)  and  simple  meteorological  parameters 
are  the  meteorological  input  for  the  program. 
Detailed  meteorological  phenomena  such  as 
explosive  deepening  of  storms,  violent  changes

An  objective  regional  trajectory  analysis 
scheme  has  been  combined  with  a  Gaussian 
diffusion  model  to  yield  a  technique  called 
MESODIF  (mesoscale  diffusion).  The  trajectory 
analysis  scheme  utilized  wind  data  from  a  net- 
work of  tower-mounted  wind  sensors  to  con- 
sider the  effects  of  spatial  variabilities  of 
horizontal  wind  flow  near  the  surface,  incor- 
porated time  changes  in  rates  of  diffusion,  and 
used  an  upper  level  lid  to  vertical  mixing.  The 
diagnostic  comparisons  of  regional  dispersion 
effects  from  each  technique  showed  significant 
differences  over  the  range  of  scales  con- 
sidered. For  short  or  accidental  type  of  emis- 
sions, the  greatest  shortcoming  of  the  single 
wind-station  dispersion  model  was  its  failure  to 
identify,  when  applied  within  a  region  of  spa- 
tially variable  winds,  the  subregion  which 
would  be  affected.  Current  usage  of  the  wind 
rose  technique  for  regional  dispersion  calcula- 
tions, especially  at  the  longer  distances,  incor- 
porates some  systematic  bias  in  the  evalua- 
tions. These  shortcomings  are  points  of  con- 
cern and  should  be  reconciled  with  whatever 
impact  assessment  schemes  are  to  be  utilized 
within  the  mesoscale  or  regional  domain.

system  that  automates  many  of  the  steps 
required  to  obtain  electron  density  versus  'true' 
height  profiles  from  film  ionogram  data.  The 
semi-automated  system  retains  the  judgment 
and  pattern  recognition  capabilities  of  trained

traces  of  interest,  but  relies  on  automatic  data 
processing  techniques  to  perform  essentially 
all  other  functions.  The  computer  subroutines 
documented  in  this  memorandum  relate 
primarily  to  the  processing  of  the  data  after  the 
ionogram  traces  have  been  digitized,  but  before 
the  true  height  is  computed.  These  inter- 
mediate data  processing  steps  are  necessary  to 
provide  accurate  digital  input  data  for  the  true 
height  computer  program.

With  a  view  to  assessing  the  validity  of  current 
probabilistic  approaches  to  the  definition  of 
design  wind  speeds,  a  study  was  undertaken  of 
extreme  wind  speeds  based  on  records  taken  at

analyzing  extreme  value  data,  a  computer  pro- 
gram was  developed,  which  is  described 
herein.  The  following  results  were  obtained:  (1) 
The  assumption  that  a  single  probability  dis- 
tribution is  universally  applicable  to  all  extreme 
wind  data  sets  in  a  given  type  of  climate  was  not 
confirmed,  and  (2)  predictions  of  100-year  wind 
speeds  based  on  overlapping  20-year  sets  of 
data  taken  at  the  same  station  differed  between 
themselves  by  as  much  as  100%.  Similar  predic- 
tions for  1000-year  winds  differed  by  as  much 
as  a  few  hundred  %.  Since  wind  pressures  are 
proportional  to  the  square  of  the  wind  speeds, 
errors  of  such  magnitude  are  unacceptably 
high  for  structural  design  purposes.

A  vertically  integrated  two-dimensional  numeri- 
cal hydrodynamic  model  is  developed  for  simu- 
lation of  hurricane  surge  in  Apalachicola  Bay. 
Standard  explicit  time  differencing  is  used  in 
conjunction  with  a  single  Richardson  lattice. 
Model  features  include  finite  amplitude  effects, 
space  variable  wind  velocities,  and  parame- 
terization of  flooding  of  terrain,  overtopping  of 
barrier  islands  and  flow  through  narrow  passes. 
The  model  utilizes  the  results  of  C.P.  Jelesnian- 
ski's  SPLASH  model  computation  for  open 
coast  surge  as  input  seaward  of  the  Bay  and 
continues  the  same  storm  tract  and  wind  field 
as  used  in  the  SPLASH  computation  across  the 
Bay.  The  Bay  model  was  calibrated  for  the  as- 
tronomical tides  and  verified  against  hurricane 
Agnes.  The  response  of  Apalachicola  Bay  has 
been  determined  from  numerical  computations 
for  a  variety  of  hypothetical  hurricanes  as 
specified  by  various  storm  parameters.  Surge 
heights  in  the  Bay  increase  with  hurricane  cen- 
tral pressure  depression  in  a  nearly  linear 
fashion  as  does  the  open  coast  surge.  An  im- 
portant parameter  is  the  duration  that  the  open 
coast  surge  remains  high,  a  function  of  the  for- 
ward speed  of  the  storm  and,  to  a  lesser  extent, 
the  radius  of  the  maximum  winds.

This  work  recognizes  rainfall  and  runoff  as  mul- 
tidimensional stochastic  processes.  Using  the 
knowledge  of  such  processes,  a  procedure  for 
designing  an  optimal  network  to  measure  the 
total  precipitation  of  an  event  over  a  fixed  area 
is  given.  The  methodology  used   in  this  static 


problem  allows  consideration  of  the  following 
aspects  of  network  design:  (1)  Spatial  correla- 
tion of  process  (2)  errors  of  measurement 
techniques  and  their  correlation  (3)  non- 
homogeneous  sampling  costs.  Optimal  net- 
works are  given  in  terms  of  the  number  and  lo- 
cation of  stations  together  with  the  resulting 
cost  and  mean  square  error  of  estimation.  The 
relation  between  rainfall  and  runoff  is  recog- 
nized as  a  dynamic  problem.  A  statistically  non- 
stationary,  multi-dimensional  rainfall  generator 
is  suggested.  The  suggested  rainfall  model  is 
used  together  with  a  runoff  model  to  study  the

Certain  shortcomings  of  current  procedures  for 
computing  alongwind  structural  response  have 
been  shown  to  result  in  unrealistic  estimates  of 
tall  building  behavior  under  the  action  of  strong 
winds.  Differences  between  predictions  of  fluc- 
tuating response  based  on  various  such 
procedures  may  be  as  high  as  200%.  In  recent 
years,  advances  in  the  state  of  the  art  have  been 
made  which  provide  a  basis  for  significantly  im- 
proved alongwind  response  predictions.  The 
purpose  of  the  present  work  is  to  present  a 
procedure  for  calculating  alongwind  response 
which  incorporates  and  utilizes  these  ad- 
vances. The  basic  structural,  meteorological 
and  aerodynamic  models  employed  are 
described,  and  expressions  for  the  alongwind 
deflections  and  accelerations,  consistent  with 
those  models,  are  derived.  A  computer  program 
is  presented  for  calculating  the  alongwind 
response  of  structures  with  unusual  modal 
shapes  or  for  which  the  contribution  of  the 
higher  modes  to  the  response  is  significant.

Research  conducted  between  1  July  1975  and 
31  October  1976  is  reported.  A  "physical-adap- 
tive" model  of  the  space-conditioning  demand 
for  energy  and  its  response  to  changes  in 
weather  regimes  was  developed.  This  model  in- 
cludes parameters  pertaining  to  engineering 
factors  of  building  construction,  to  weather-re- 
lated factors,  and  to  socio-economic  factors. 
Preliminary  testing  of  several  components  of 
the  model  on  the  city  of  Greeley,  Colorado, 
yielded  most  encouraging  results.  Other  com- 
ponents, especially  those  pertaining  to  socio- 
economic factors,  are  still  under  development. 
Expansion  of  model  applications  to  different 
types  of  structures  and  larger  regions  is 
presently  underway.  A  CRT-display  model  for 
energy  demand  within  the  conterminous  United 
States  also  has  passed  preliminary  tests.  A 
major  effort  was  expended  to  obtain  disag- 
gregated data  on  energy  use  from  utility  com- 
panies throughout  the  United  States.  The  study 
of  atmospheric  variability  revealed  that  the  22- 
to  26-day  vacillation  in  the  potential  and  kinetic 
energy  modes  of  the  Northern  Hemisphere  is 
related  to  the  behavior  of  the  planetary  long- 
waves,  and  that  the  midwinter  dip  in  zonal 
available  potential  energy  is  reflected  in  the 
development  of  blocking  highs.  Attempts  to 
classify  weather  patterns  over  the  eastern  and 
central  United  States  have  proceeded  satisfac- 
torily to  the  point  where  testing  of  our  method 
for  longer  time  periods  appears  desirable.  (ERA

In  the  report  the  annual  mean  and  zonally 
averaged  concentration  of  krypton-85  in  the 
troposphere  and  lower  stratosphere  of  the 
Northern  and  Southern  hemispheres  is  calcu- 
lated on  the  basis  of  a  numerical  solution  with  a 
computer  of  boundary  problems  for  an  equa- 
tion of  a  numerical  derivation  of  a  model  of  the 
global  spread  of  the  admixture  in  a  meridional 
plane  of  the  atmosphere  as  constructed  by 
Karol.  The  results  of  the  calculations  with  vari- 
ous combinations  of  the  parameters  of  the 
transfer  of  the  model  are  compared  with  results 
of  measurements  both  in  our  country  and 
abroad.  Predicted  distribution  of  the  expected 
levels  of  concentration  of  krypton-85  have  been 
obtained  up  to  the  year  2000.  The  correspond- 
ing radiation  dose  strengths  in  the  air  for  the 
whole  body  and  for  individual  organs  of  the 
human  body  have  also  been  calculated.  These 
dose  strengths  and  concentrations  are  com- 
pared with  the  maximum  allowable  levels  which 
have  been  established  on  the  basis  of  the  cur- 
rent recommendations  of  the  International

A  generalized,  three-dimensional  Monte  Carlo 
model  and  computer  code  (SPOOR)  are 
described  for  simulating  atmospheric  transport 
and  dispersal  of  small  pollutant  clouds.  A  cloud 
is  represented  by  a  large  number  of  particles 
that  we  track  by  statistically  sampling  simulated 
wind  and  turbulence  fields.  These  fields  are 
based  on  generalized  wind  data  for  large-scale 
flow  and  turbulent  energy  spectra  for  the 
micro-  and  mesoscales.  The  large-scale  field 
can  be  input  from  a  climatological  data  base,  or 
by  means  of  real-time  analyses,  or  from  a 
separate,  subjectively  defined  data  base.  We  in- 
troduce the  micro-  and  mesoscale  wind  fluc- 
tuations through  a  power  spectral  density,  to 
include  effects  from  a  broad  spectrum  of  turbu- 
lent-energy scales.  The  role  of  turbulence  is 
simulated  in  both  meander  and  dispersal.  Com- 
plex flow  fields  and  time-dependent  diffusion 
rates  are  accounted  for  naturally,  and  shear  ef- 
fects are  simulated  automatically  in  the  ensem- 
ble of  particle  trajectories.  An  important  ad- 
junct has  been  the  development  of  computer- 
graphics  displays.  These  include  two-  and 
three-dimensional  (perspective)  snapshots  and 
color  motion  pictures  of  particle  ensembles, 
plus  running  displays  of  differential  and  in- 
tegral cloud  characteristics.  The  model's  ver- 
satility makes  it  a  valuable  atmospheric 
research   tool   that  we  can   adapt  easily   into 


broader,  multicomponent  systems-analysis 
codes.  Removal,  transformation,  dry  or  wet 
deposition,  and  resuspension  of  contaminant 
particles  can  be  readily  included.

A  generalized,  three-dimensional,  integrated

mate collateral-damage  threats  from  precipita- 
tion-scavenging (rainout)  of  airborne  debris- 
clouds  from  defensive  tactical  nuclear  engage- 
ments. This  code  system,  called  ACRA  for  At- 
mospheric-Contaminant Rainout  Assessment, 
is  based  on  Monte  Carlo  statistical  simulation 
methods  that  allow  realistic,  unbiased  simula- 
tions of  probabilistic  storm,  wind,  and 
precipitation  fields  that  determine  actual  mag- 
nitudes and  probabilities  of  rainout  threats. 
Detailed  models  (or  data  bases)  are  included  for 
synoptic-scale  storm  and  wind  fields;  debris 
transport  and  dispersal  (with  the  roles  of  com- 
plex flow  fields,  time-dependent  diffusion,  and 
multidimensional  shear  effects  accounted  for 
automatically);  microscopic  debris-precipita-

air-to-ground  debris  transport;  local  demo-

populations;  and  nonlinear  effects  accumula- 
tions from  multishot  scenarios.  The  authors 
simulated  several  hundred  representative  shots 
for  West  European  scenarios  and  climates  to 
study  single-shot  and  multishot  sensitivities  of 
rainout  effects  to  variations  in  pertinent  physi-

A  numerical  solution  of  the  turbulent  mass 
transport  equation  utilizing  the  concept  of  eddy 
diffusivity  is  presented  as  an  efficient  method  of 
investigating  turbulent  mass  transport  in  boun-

program  is  used  to  study  the  two-dimensional 
diffusion  of  ammonia,  from  a  line  source  on  the 
surface,  into  a  turbulent  boundary  layer  over  a 
flat  plate.  The  results  of  the  numerical  solution 
are  compared  with  experimental  data  to  verify 
the  results  of  the  solution.  Several  other  solu- 
tions to  diffusion  problems  are  presented  to  il- 
lustrate the  versatility  of  the  computer  program 
and  to  provide  some  insight  into  the  problem  of 
mass  diffusion  as  a  whole.  (Author)

The  data  obtained  in  earth  orbit  by  the  Radia- 
tion and  Meteoroid  Satellite  (RMS)  were  in- 
terpreted and  reduced  to  a  form  which  will  be 
usable  by  future  space  experimenters.  The 
required  tasks  are  detailed.  Computer  pro- 
grams were  written  which  lifted  the  raw  data 
and  associated  emphemeris  data  from  the  GFE 
magnetic  tapes.  The  engineering  data  was  then 
used  to  evaluate  the  performance  of  the 
spacecraft  and  the  experiments.  The  radiation 
data  was  used  to  prepare  flux,  spectral,  and 
dose  maps  of  the  South  Atlantic  magnetic 
anomaly  where  possible.  The  meteoroid  data 
was  used  to  determine  a  rough  estimate  of  the 
meteoroid  flux  and  in  general  evaluate  the  per- 
formance of  the  thin-film  meteoroid  sensors. 
The  degree  of  success  of  the  RMS  mission  was 
evaluated  in  light  of  the  separation  anomaly 
which  occurred  between  RMS  and  OFO  during 
launch.  (Author)

determined  from  the  LDV  data  are  within  5%  of 
other  anemometer  data  for  long  time  periods, 
and  the  LDV  measures  higher  velocities.

The  feasibility  of  performing  data  reduction 
techniques  with  a  hybrid  computer  was  studied. 
The  data  was  obtained  from  the  flight  of  a 
parachute  born  probe  through  the  D-region  of 
the  ionosphere.  A  presentation  of  the  theory  of 
blunt  probe  operation  is  included  with  empha- 
sis on  the  equations  necessary  to  perform  the 
analysis.  This  is  followed  by  a  discussion  of 
computer  program  development.  Included  in 
this  discussion  is  a  comparison  of  computer 
and  hand  reduction  results  for  the  blunt  probe 
launched  on  31  January  1972.  The  comparison 
showed  that  it  was  both  feasible  and  desirable 
to  use  the  computer  for  data  reduction.  The 
results  of  computer  data  reduction  performed 
on  flight  data  acquired  from  five  blunt  probes

Simultaneous  observations  of  low  energy  elec-

experiment  on  the  OGO-3  satellite  and  from  the

were  processed  and  compared.  The  OV1-18 
carried  thirteen  magnetic  electron  spectrome- 
ters designed  to  measure  the  intensity,  angular, 
and  energy  distributions  of  the  auroral  elec- 
trons and  protons  in  the  energy  range  below  50 
keV.  Two  computer  programs  were  developed 
for  reduction  of  the  OV1-18  data.  One  program 
computed  the  various  plasma  properties  at  one 
second  intervals  as  a  function  of  Universal  Time

survey  plots  showing  the  outputs  of  the  various

Techniques  to  calculate  the  transfer  functions 
relating  lightning-induced  voltages  in  aircraft 
electrical  circuits  to  aircraft  physical  charac-

discussed.  The  analytical  work  was  carried  out

the  electrical  circuits  of  an  F89-J  aircraft.  A 
computer  program,  ETCAL,  developed  earlier 
to  calculate  resistive  and  inductive  transfer 
functions  is  refined  to  account  for  skin  effect,

providing  results  more  valid  over  a  wider  range

A  computer  program,  WING,  is  derived  to  calcu-

The  structure  of  the  plasmasphere  was  studied 
as  seen  by  radiosounder  measurements  aboard 
the  Alovetti-2  satellite.  Magnetic  tape  data  files 
were  obtained  from  the  NASA  Ames  Research 
Center  to  give  a  reasonably  complete  set  of 
high  latitude  electron  density  profiles.  Con- 
siderable effort  was  expended  to  develop 
models  of  ion  flow  in  the  topside  ionosphere. 
These  models  took  both  H(0)  and  O(0)  into  ac- 
count and  permitted  various  parameter  studies 
to  be  made  of  the  various  factors  which  affect 
H(0)  escape  in  polar  wind  flows.  The  results  of 
these  studies  are  included.  Extensive  computer 
programs  were  written  to  display  the  measured 
electron  density-  profiles  in  ways  useful  to 
geophysical  analysis.  The  expected  mid- 
latitude  trough  was  easily  discernable  in  the 
nightime  ionosphere  at  locations  expected 
from  similar  observations  of  the  plasmapause. 
In  the  dayside  ionosphere,  however,  it  proved 
extremely  difficult  to  find  any  trough-like 
phenomena.  Using  the  previously  developed 
computer  models,  it  was  possible  to  study  the 
region  where  the  plasmapause  appeared  to  be 
absent.  It  was  found  that  over  much  of  the 
dayside,  large  fluxes  were  computed  well  inside 
the  plasmapause  extending  down  to  L-shells  as 
low  as  2.5.  (Author)

A  study  to  further  improve  NASA's  global  cloud 
statistics  for  mission  simulation  is  reported.  Re- 
gional homogeneity  in  cloud  types  was  ex- 
amined; most  of  the  original  region  boundaries 
defined  for  cloud  cover  amount  in  previous  stu- 
dies were  supported  by  the  statistics  on  cloud 
types  and  the  number  of  cloud  layers.  Condi- 
tionality  in  cloud  statistics  was  also  examined 
with  special  emphasis  on  temporal  and  spatial 
dependencies,  and  cloud  type  interdepen- 
dence. Temporal  conditionality  was  found  up  to 
12  hours,  and  spatial  conditionality  up  to  200 
miles;  the  diurnal  cycle  in  convective  cloudi- 
ness was  clearly  evident.  As  expected,  the  joint 
occurrence  of  different  cloud  types  reflected 
the  dynamic  processes  which  form  the  clouds. 
Other  phases  of  the  study  improved  the  cloud 
type  statistics  for  several  region  and  proposed  a 
mission  simulation  scheme  combining  the  4- 
dimensional  atmospheric  model,  sponsored  by 
MSFC,  with  the  global  cloud  model.  (Author)

A  system  consisting  of  two  superimposed 
layers  of  liquid  of  different  densities,  with  a  thin 
transition  layer  at  the  interface,  provides  a  good 
laboratory  model  of  an  ocean  thermocline  or  of 
an  atmospheric  inversion  layer.  This  research 
was  to  gain  knowledge  about  the  propagation 
of  disturbances  within  these  two  geophysical 
systems.  The  technique  used  was  to  observe 
the  propagation  of  internal  waves  and  of  up- 
stream influence  within  the  density-gradient  re- 
gion   between    the   two    layers   of    liquid.   The 


54 


disturbances  created  by  the  motion  of  a  vertical 
flat  plate,  which  was  moved  longitudinally 
through  this  region,  were  examined  both  ex- 
perimentally and  numerically.  An  upstream  in- 
fluence, which  resulted  from  a  balance  of  iner- 
tial  and  gravitational  forces,  was  observed,  and 
it  was  possible  to  predict  the  behavior  of  this  in- 
fluence with  the  numerical  model.  The  predic- 
tion included  a  description  of  the  propagation 
of  the  upstream  influence  to  steadily  increasing 
distances  from  the  flat  plate  and  the  shapes  and 
magnitudes  of  the  velocity  profiles.  (Author)

An  empirical  atmospheric  model  was 
developed  which  generates  values  for  pressure, 
density,  temperature,  and  winds  from  surface 
levels  to  orbital  altitudes.  The  output  parame- 
ters consist  of  components  for:  (1 )  latitude,  lon- 
gitude, and  altitude  dependent  monthly  and  an- 
nual means;  (2)  quasi-biennial  oscillations;  and 
(3)  random  perturbations  to  simulate  partially 
the  variability  due  to  synoptic,  diurnal,  planeta- 
ry wave,  and  gravity  wave  variations.  Quasi- 
biennial  and  random  variation  perturbations 
are  computed  from  parameters  determined 
from  various  empirical  studies  and  are  added  to 
the  monthly  mean  values.  This  model  has  been 
developed  as  a  computer  program  called 
PROFILE  which  can  be  used  to  generate  al- 
titude profiles  of  atmospheric  parameters  along 
any  simulated  trajectory  through  the  at- 
mosphere. The  PROFILE  program  was 
developed  for  design  applications  in  the  space 
shuttle  program.  Other  applications  of  the 
model  are  discussed,  such  as  forglobal  circula- 
tion and  diffusion  studies,  and  for  generating 
profiles  for  comparison  with  other  atmospheric 
measurement  techniques,  (e.g.  satellite  mea- 
sured temperature  profiles).  (Author)

Basic  equations  for  calculating  the  upwelling 
atmospheric  radiation  are  presented  which  ac- 
count for  various  sources  of  radiation  coming 
out  at  the  top  of  the  atmosphere.  The  theoreti-

(line-by-line  and  quasi-random  band  model) 
and  the  computational  procedures  used  for  the 
evaluation  of  the  transmittance  and  radiance 
are  discussed  in  detail.  By  employing  the 
Lorentz  line-by-line  and  quasi-random  com- 
puter programs,  model  calculations  were  made 
to  determine  the  upwelling  radiance  and  signal 
change  in  the  wave  number  interval  of  CO  fun- 
damental band.  These  results  are  useful  in 
determining  the  effects  of  different  interfering 
molecules,  water  vapor  profiles,  ground  tem- 
peratures, and  ground  emittances  on  the  up- 
welling radiance  and  signal  change.  This  infor-

potential  temperature,  horizontal  wind,  water

designed  to  simulate  the  formation,  develop-

response  to  transfer  of  heat  and  moisture 
between  the  atmosphere  and  the  surface  as 
driven  by  advection  over  horizontal  discontinui-

The  theory  of  determining  mean  thermospheric 
zonal  winds  above  150  km  by  analysis  of  the 
inclination  change  of  satellites  is  discussed. 
The  decrease  of  upper-atmospheric  rotation 
rate  from  1.4  times  the  earth's  angular  velocity 
at  a  height  of  375  km  to  0.7  at  500  km,  from  the 
analysis  of  only  three  satellite  orbits,  was 
derived  without  eliminating  the  effects  of  solar 
radiation  pressure.  These  satellites  do  not  allow 
the  exact  computation  of  radiation  pressure  ef- 
fects due  to  their  irregular  shape.  Therefore  the 
orbit  of  the  balloon  satellite  Explorer  24  (1964- 
76A)  has  been  thoroughly  analyzed  at  perigee 
heights  between  480  and  600  km  and  during 
various  time  intervals.  A  computer  program  was 
developed  forthis  purpose,  which  directly  com- 
putes the  zonal  wind  magnitude  with  regard  to 
all  significant  perturbations  usinq  the  method 
of  least  squares.  The  parts  of  the  program 
which  compute  the  radiation  pressure  effects 
have  previously  been  tested  with  the  aid  of  the 
orbit  of  the  balloon  satellite  Dash  2  (1963-30D). 
The  results  from  Explorer  24  could  be  changed 
by  altering  the  investigated  time  intervals.  Al- 
together they  indicate  a  corotation  of  the  at- 
mosphere and  the  earth  at  heights  of  550  to  600 
km.  A  local  time  dependence  of  zonal  winds  in 
this  height  region  could  not  be  detected.

The  National  Aeronautics  and  Space  Adminis- 
tration/Marshall Space  Flight  Center  multilayer 
diffusion  algorithms  have  been  specialized  for 
the  prediction  of  the  surface  impact  for  the 
dispersive  transport  of  the  exhaust  effluents 
from  the  launch  of  a  Delta-Thor  vehicle.  This 
specialization  permits  these  transport  predic- 
tions to  be  made  at  the  launch  range  in  real 
time  so  that  the  effluent  monitoring  teams  can 
optimize  their  monitoring  grids.  Basically,  the 
data  reduction  routine  requires  only  the 
meteorology  profiles  for  the  thermodynamics 
and  kinematics  of  the  atmosphere  as  an  input. 
These  profiles  are  graphed  along  with  the 
resulting  exhaust  cloud  rise  history,  the  center- 
line  concentrations  and  dosages,  and  the 
hydrogen  chloride  isopleths.  (Author)

A  simple  procedure  and  computer  program 
were  developed  for  retrieving  the  surface  tem- 
perature from  the  measurement  of  upwelling 
infrared  radiance  in  a  single  spectral  region  in 
the  atmosphere.  The  program  evaluates  the 
total  upwelling  radiance  at  any  altitude  in  the 
region  of  the  CO  fundamental  band  (2070-2220 
1/cm)  for  several  values  of  surface  temperature. 
Actual  surface  temperature  is  inferred  by  inter- 
polation of  the  measured  upwelling  radiance 
between  the  computed  values  of  radiance  for 
the  same  altitude.  Sensitivity  calculations  were 
made  to  determine  the  effect  of  uncertainty  in 
various  surface,  atmospheric  and  experimental 
parameters  on  the  inferred  value  of  surface 
temperature.  It  is  found  that  the  uncertainties  in 
water  vapor  concentration  and  surface 
emittance  are  the  most  important  factors  affect- 
ing the  accuracy  of  the  inferred  value  of  surface 
temperature.  (Author)

The  influence  of  real  satellite  aerodynamics  on 
the  determination  of  upper  atmospheric  density 
was  investigated.  A  method  of  analysis  of  satel- 
lite drag  data  is  presented  which  includes  the 
effect  of  satellite  lift  and  the  variation  in 
aerodynamic  properties  around  the  orbit.  The 
studies  indicate  that  satellite  lift  may  be  respon- 
sible for  the  observed  orbit  precession  rather 
than  a  super  rotation  of  the  upper  atmosphere. 
The  influence  of  simplifying  assumptions  con- 
cerning the  aerodynamics  of  objects  in  falling 
sphere  analysis  were  evaluated  and  an  im- 
proved method  of  analysis  was  developed. 
Wind  tunnel  data  was  used  to  develop  more  ac- 
curate drag  coefficient  relationships  for  study- 
ing altitudes  between  80  and  120  Km.  The  im- 
proved drag  coefficient  relationships  revealed  a 
considerable  error  in  previous  falling  sphere 
drag  interpretation.  These  data  were  reanalyzed 
using  the  more  accurate  relationships. 
Theoretical  investigations  of  the  drag  coeffi- 
cient in  the  very  low  speed  ratio  region  were 
also  conducted.  (Author)

The  Global  Reference  Atmospheric  Model  was 
improved  to  produce  more  realistic  simulations 
of  vertical  profiles  of  atmospheric  parameters. 
A  revised  two  scale  random  perturbation  model 
using  perturbation  magnitudes  which  are  ad- 
justed to  conform  to  constraints  imposed  by  the 
perfect  gas  law  and  the  hydrostatic  condition  is 
described.  The  two  scale  perturbation  model 
produces  appropriately  correlated  (horizontally 
and  vertically)  small  scale  and  large  scale  per- 
turbations. These  stochastically  simulated  per- 
turbations are  representative  of  the  magnitudes 
and  wavelengths  of  perturbations  produced  by 
tides  and  planetary  scale  waves  (large  scale) 
and  turbulence  and  gravity  waves  (small  scale). 
Other  new  features  of  the  model  are:  (1)  a 
second  order  geostrophic  wind  relation  for  use 
at  low  latitudes  which  does  not  blow  up  at  low 
latitudes  as  the  ordinary  geostrophic  relation 
does;  and  (2)  revised  quasi-biennial  amplitudes 
and  phases  and  revised  stationary  perturba- 
tions, based  on  data  through  1972.

Over  700  far  UV  photos  were  obtained  with  the

Nov.  1973  -  28  Jan.  1974)  and  from  the  Apollo-

alpha  geocorona  was  found  to  fit  R.  R.  Meier's 
model,  and  the  tropical  airglow  belts  were  mea- 
sured quantitatively.  The  history  of  Comet 
Kohoutek's  Ly-alpha  halo  (and  lack  of  an  ox-

Far  UV  emissions  from  the  Large  Magellanic 
Cloud  were  also  measured  quantitatively  and 
compared  with  ground-based  measurements  of 
stellar  associations  and  nebulae.  Computer

original  film  and  to  locate  and  sum  density- 
volumes  in  each  starlike  image.  In  addition, 
thousands  of  stars  were  identified  and  their  far

A  near  real-time  ice  information  system 
designed  to  aid  arctic  coast  shipping  along  the

utilizes  a  X-band  Side  Looking  Airborne  Radar 
(SLAR)  mounted  aboard  a  U.S.  Coast  Guard 
HC-130B  aircraft.  Radar  mapping  procedures 
showing  the  type,  areal  distribution  and  con- 
centration of  ice  cover  were  developed.  In  order 
to  guide  vessel  operational  movements,  near 
real-time  SLAR  image  data  were  transmitted 
directly  from  the  SLAR  aircraft  to  Barrow, 
Alaska  and  the  U.S.  Coast  Guard  icebreaker 
Glacier.  In  addition,  SLAR  image  data  were 
transmitted  in  real  time  to  Cleveland,  Ohio  via

An  investigation  of  sea  and  sky  background 
radiance  as  a  function  of  elevation  in  three

transmission  model  as  a  subroutine,  was 
developed  to  study  the  separate  influence  of  a 
few  meteorological  parameters  on  these  func- 
tions. The  occurrence  of  a  dip  in  the  apparent 
temperature  of  the  sea  near  the  horizon  has 
notably  been  analyzed.  Results  are  summarized 
of  the  measurements  of  the  background  radia- 
tion around  the  horizon,  made  during  a  year  by 
a  scanning  radiometer  at  an  altitude  of  30  meter 
above  the  sea  surface.  The  radiance  of  the  sky 
is  measured  and  computed  also  for  higher 
elevations  (0-90  deg).  Computations  and  mea- 
surements are  in  very  good  agreement  except 
for  the  small  interval  3.4-4.1  micrometers.  The 
latter  might  be  caused  by  an  overestimation  of 
the  transmission  by  the  Lowtran  3  model  in  this 
wavelength  band.

The  experimental  method  consists  in  creating 
artificial  clouds  within  the  stratosphere,  and  in 
observing  their  evolution  from  the  ground.  The 
observation  means  used  are  either  a  lidar  and  a 
still  camera,  or  two  ballistic  chambers  and  two 
still  cameras.  The  measurements  carried  out 
allow  determination  of  cloud  motion  and  cloud 
sizes,  during  an  average  of  600  sec.  A  numerical 
model  was  realized  which  makes  it  possible  to 
simulate  the  evolution  of  these  clouds  and  to 
emphasize  the  influence  of  turbulent  mixing 
and  wind  shear.  With  this  model  and  experi- 
mental results  the  horizontal  diffusion  coeffi- 
cients and  their  variations  with  scale  can  be 
determined.  The  values  found  are  between  0.5 
and  11  sq  m/s,  for  a  time  of  300  sec.  Some 
values  of  the  vertical  diffusion  coefficient  were 
also  measured.  The  results  obtained  are 
discussed.  A  study  of  the  microstructure  of 
clouds  permitted  the  study  of  the  phenomena  at 
a  smaller  scale.

A  concise  model  has  been  developed  to  analyze 
uncertainties  in  stratospheric  perturbations,  yet 
uses  a  minimum  of  computer  time  and  is 
complete  enough  to  represent  the  results  of 
more  complex  models.  The  steady  state  model 
applies  iteration  to  achieve  coupling  between 
interacting  species.  The  species  are  determined 
from  diffusion  equations  with  appropriate 
sources  and  sinks.  Diurnal  effects  due  to 
chlorine  nitrate  formation  are  accounted  for  by 
analytic  approximation.  The  model  has  been 
used  to  evaluate  steady  state  perturbations  due 
to  injections  of  chlorine  and  NO(X).

A  data  base  management  system  is  identified, 
developed  to  provide  flexible  access  to  data 
sets  produced  by  GARP  during  its  data  systems 
tests.  The  content  and  coverage  of  the  data 
base  are  defined  and  a  computer-aided,  in- 
teractive information  storage  and  retrieval 
system,  implemented  to  facilitate  access  to  user 
specified  data  subsets,  is  described.  The  com- 
puter programs  developed  to  provide  the  capa- 
bility were  implemented  on  the  highly  interac- 
tive, minicomputer-based  AOIPS  and  are 
referred  to  as  the  data  retrieval  system  (DRS). 
Implemented  as  a  user  interactive  but  menu 
guided  system,  the  DRS  permits  users  to  inven- 
tory the  data  tape  library  and  create  duplicate 
or  subset  data  sets  based  on  a  user  selected 
window  defined  by  time  and  latitude/longitude 
boundaries.  The  DRS  permits  users  to  select, 
display,  or.produce  formatted  hard  copy  of  in- 
dividual data  items  contained  within  the  data 
records.

A  more  comprehensive  model  for  stratospheric 
chemistry  and  transport  theory  was  developed 


for  the  purpose  of  aiding  predictions  of 
changes  in  the  stratospheric  ozone  content  as  a

vant meteorological  quantities  which  are  func-

constructed  by  the  best  mathematical  approach 
on  a  large  IBM  S360  in  American  National  Stan-

and  an  assessment  device  used  to  evaluate

The  first  year's  data  from  the  Nimbus  4

been  archived  in  the  National  Space  Science

in  the  ultraviolet  measured  by  the  satellite  were 
used  to  compute  the  global  total  ozone  for  the 
period  April  1970  -  April  1971.  The  data  sets 
now  in  the  NSSDC  are  the  results  obtained  by 
the  Ozone  Processing  Team,  which  has 
processed  the  data  with  the  purpose  of  deter- 
mining the  best  quality  of  the  data.  There  are 
four  basic  sets  of  data  available  in  the  NSSDC 
representing  various  stages  in  processing.  The 
primary  data  base  contains  organized  and 
cleaned  data  in  telemetry  units.  The  radiance 
data  has  had  most  of  the  engineering  calibra-

is  the  result  of  computations  to  obtain  the  total 
ozone;  the  Compressed  Total  Ozone  data  is  a 
convenient  condensation  of  the  detailed  total

with  the  GISS  model  from  observed  initial  con- 
ditions. In  a  replication  experiment,  two  of 
these  computations  generated  slightly  different 
monthly  mean  states,  apparently  due  to  the 
schedule  of  interruptions  on  the  computer.  The 
root-mean-square  errors  of  replication  over  the 
Northern  Hemisphere  were  found  to  be  about  2 
mb,  20  m,  and  1  K  for  sea-level  pressure,  500

Hemisphere  were  consistent  with  those  from 
earlier  GISS  model  experiments.

The  use  of  multichannel  automatic  data  recor- 
ders has  necessitated  the  development  of 
techniques  for  rapid  analysis  and  presentation 
of  data.  A  computer  program  was  developed  to 


62 


plot  time  dependent  data  from  a  storage  matrix. 
The  body  of  the  program,  entitled  TIMEPLOT,  is 
written  in  FORTRAN  IV.  To  minimize  the  run 
time  required,  the  input  and  output  subroutines 
are  written  in  F  level  COBOL.  Time,  which  may 
range  from  1  hour  to  16  days,  is  plotted  on  the 
abscissa.  The  program  computes  the  intervals 
at  which  labels  are  placed  and  determines  the 
required  annotation.  Data  may  be  plotted  as 
frequently  as  one  observation  per  minute  or  as 
infrequently  as  one  observation  per  day.  The  or- 
dinate may  represent  any  parameter.  A  single 
parameter  may  be  plotted  or  several  parameters 
may  be  superimposed  upon  each  other.  Com- 
binations may  be  arranged  on  a  single  time 
axis.  The  program  was  designed  with  special 
features  to  facilitate  the  plotting  of  microcli- 
matic, micrometeorological,  and  other  types  of 
time-dependant  data.  Plots  drawn  in  india  ink 
may  be  photographically  reduced  for  use  in  re- 
ports and  journal  articles.  Associated  utility 
programs  are  also  described.  (Author)

Computer  programs  have  use  in  precipitation 
management  experiments.  Operational  use  of 
computers  and  computer  products  has  been 
limited,  however,  because  of  several  limitations 
which  restrict  their  use.  Scientists  conducting 
precipitation  management  operations  need 
user-oriented  computer  products  specifically 
designed  for  their  needs.  Several  numerical 
models  and  programs  have  been  studied  and 
tested.  A  philosophy  for  the  field  use  of  compu- 
ters has  been  developed.  From  this  has  grown  a 
system  for  transmitting  data  and  computer 
products  to  field  users.  This  system  has  un- 
dergone a  series  of  field  tests  and  has  been 
carefully  evaluated.  This  system  has  been  made 
operational  by  the  Bureau  of  Reclamation,  and 
its  data  and  computer  programs  are  currently 
available  to  all  Project  Skywater  field  programs.

(examples  are  the  stacks  of  electrical  generat- 
ing or  other  major  industrial  plants  and 
highways,  etc.);  numerous  minor  sources 
which  are  treated  as  continuous  area  sources; 
and  sources  beyond  the  boundary  of  the  model.

A  readily  usable  model  was  developed  for 
evaluating  the  extent  of  plumes  from  large 
evaporative  cooling  towers.  Mathematical 
models  were  used  to  describe  the  dynamics  of 
the  wet  cooling  tower  plume  and  its  interaction 
with  the  environment.  Primary  emphasis  was 
placed  on  predicting  the  height  of  the  plume. 
Classical  atmosphere  diffusion  theory  was  used 
to  determine  the  downwind  spread.  The  satura- 
tion deficit  of  the  atmosphere  controls  the 
downwind  spread  of  and  fogging  used  by  the 
plume.  A  map  of  the  U.S.  indicating  locations  of 
potential  adverse  atmospheric  effects  due  to 
cooling  towers  can  be  used  in  conjunction  with 
local  data.  Appendix  contains  a  description  of

The  report  describes  a  digital  computer  pro-

over  an  area  using  the  Thiessen  method.  The 
area  can  be  of  any  shape  and  there  is  no  neces- 
sity for  the  rain-gauge  network  to  be  the  same 
for  all  storms.  It  is  suggested  that  the  program 
may  have  applications  outside  the  field  of

The  APRAC-1A  diffusion  model  was  developed 
as  a  versatile  and  practical  model  for  comput- 
ing the  concentrations  of  pollutants  at  any

from  sources  in  upwind  cities;  intraurban  diffu-

of  health.  Motor  vehicles  are  the  major  source

The  Climatological  Dispersion  Model  (CDM) 
determines  long-term  (seasonal  or  annual) 
quasi-stable  pollutant  concentrations  at  any 
ground-level  receptor  using  average  emission 
rates  from  point  and  area  sources  and  a  joint 
frequency  distribution  of  wind  direction,  wind 
speed,  and  stability  for  the  same  period.  This 
model  differs  from  the  Air  Quality  Display  Model 
(AQDM)  primarily  in  the  way  in  which  concen- 
trations are  determined  from  area  sources,  the 
use  of  Briggs'  plume  rise  formula,  and  the  use 
of  an  assumed  power  law  increase  in  wind 
speed  with  height  that  depends  on  the  stability. 
The  material  presented  in  diredted  toward  the

This  report  describes  field  measurement  and

from  plumes.  Field  measurements  of  precipita- 
tion washout  were  conducted  in  conjunction 
with  both  controlled  test  sources  and  actual

this  work  has  been  the  formulation  of  an  S02

concentrations  that  agree  favorably  with  those 
observed.  An  approximate  theoretical  analysis 
of  sulfate  washout  in  conjunction  with  field  ob- 
servations indicates  that  sulfate  formation  and 
scavenging  exhibit  a  strong  inverse  depen- 
dence on  acidity  levels  in  the  background  rain.

Monthly  rainfall  data  of  several  stations  in  Kalihi 
Basin,  Manoa  Basin,  and  Kaneohe  Area,  all  on 
Oahu,  and  the  central  sloping  area  of  Molokai 
were  correlated  to  watershed  parameters  of  the 
areas.  Distance  measured  from  the  station  to  a 
common  station  located  seaward  from  all  sta- 
tions has  proven  to  be  the  most  important  of  the 
three  parameters  studied,  the  other  two  being 
the  exposure  and  the  elevation  of  the  area.  Both 
linear  and  nonlinear  regression  functions  were 
developed.  The  central  tendency  of  the  monthly 
rainfall  for  the  high  rainfall  part  of  the 
southeastern  part  of  the  Island  of  Oahu  was 
found  to  require  approximately  forty  years  of 
record  to  stabilize.  The  intensity-duration  rela- 
tion of  intense  rain  for  specified  recurrence  in- 
terval for  the  high  rainfall  part  of  the  Manoa 
Basin  portrays  accurately  an  inverse  straight-

dinates, suggesting  extension  of  effort  to  other 
climatically  widely  different  regions  in  Hawaii.

The  observed  behavior  of  thunderstorm-type 
activity  is  used  to  formulate  a  multidimensional 
stochastic  model  for  runoff-producing  rainfall. 
In  Part  1  of  this  report  the  physical  model  of  ob- 
served activity  is  used  to  describe  the  thun- 
derstorm process,  and  probability  distributions 
are  assigned  to  all  random  variables.  This 
model  follows  the  hourly  development  of 
storms  in  terms  of  thunderstorm  clouds  and 
rainfall-producing  convective  cells.  The 
process  is  programmed,  and  use  of  the  model 
illustrated.  Part  2  approaches  several  different 
theoretical  aspects  associated  with  rainfall  and 
runoff.  A  somewhat  simplified  thunderstorm 
model  is  used  to  derive  a  probability  distribu- 
tion for  instantaneous  rainfall,  and  several 
statistical  relations  are  considered  briefly. 
There  is  a  state-of-the-art  report  on  the  effect  of 
urbanization  on  both  rainfall  and  runoff,  and  a 
statistical  regression  analysis  relating  flood 
damage  to  characteristics  of  the  watershed 
basin,  precipitation  data,  and  streamflow  data. 
Finally,  the  use  of  statistical  decision  theory 
analysis  is  illustrated.

The  design  of  many  water  resources  projects 
requires  knowledge  of  possible  long-term  rain- 
fall patterns.  A  stochastic  model  based  on  a  first 
order  Markov  chain  was  developed  to  simulate 
daily  rainfall  at  a  point.  The  model  is  applicable 
to  any  point  in  Kentucky  (and  other  areas  with 
similar    rainfall    patterns).    The    model    in    its 


present  form  is  useful  in  providing  rainfall  in- 
puts into  hydrologic  models  for  designing 
water  supply  facilities  and  other  water 
resources  systems.  The  model  uses  historical 
rainfall  data  to  estimate  the  Markov  transitional 
probabilities.  A  separate  matrix  is  estimated  for 
each  month  of  the  year.  In  this  report  7x7 
transitional  probability  matrices  were  used.  The 
model  is  capable  of  simulating  a  daily  rainfall 
record  of  any  length  based  on  the  estimated 
transitional  probabilities  and  frequency  dis- 
tributions of  rainfall  amounts  within  each  class 
interval.  The  simulated  data  have  statistical  pro- 
perties similar  to  historical  data.

Total  storm  depths  over  a  given  area  are  as- 
sumed to  be  composed  of  a  regional  com- 
ponent, explaining  the  large-scale  variations  of 
rainfall,  and  a  local  component,  explaining  the 
small-scale  variations.  In  order  to  study  the 
characteristics  of  the  regional  component,  a 
number  of  storms  over  a  given  area  are 
analyzed.  For  each  storm,  a  double  Fourier 
analysis  of  the  total  storm  depths  is  performed, 
and  the  principal  harmonics  of  the  storm  are 
determined.  This  analysis  is  aimed  to  in- 
vestigate whether  or  not  there  exists  a  per- 
sistent pattern  in  total  storm  depths  over  a 
given  area.  The  local  component,  or  storm 
residuals,  is  obtained  by  subtracting  the 
periodic  component  of  the  storm  from  the  total 
storm  depths.  It  is  assumed  that  the  residuals  of 
each  storm  are  a  sample  function  of  a 
homogeneous  random  field,  which,  in  princi- 
ple, may  be  different  for  each  storm.  The  analy- 
sis of  the  storm  residuals  has  illustrated  a 
methodology  for  the  statistical  analysis  of  areal 
rainfall  data  and  the  characterization  of 
homogeneous  isotropic  random  fields.

A  computer  model,  called  HIWAY,  that  can  be 
used  for  estimating  the  concentrations  of  non- 
reactive  pollutants  from  highway  traffic  is 
described.  This  steady-state  Gaussian  model 
can  be  applied  to  determine  air  pollution  con- 
centrations at  receptor  locations  downwind  of 
at-grade  and  cut-section  highways  located  in 
relatively  uncomplicated  terrain.  The  air  pollu- 
tion concentration  representative  of  hourly 
averaging  times  at  a  downwind  receptor  loca- 
tion is  found  by  a  numerical  integration  along 
the  length  of  each  lane  and  a  summing  of  the 
contributions  from  each  lane.  With  the  excep- 


tion of  receptors  directly  on  the  highway  or 
within  the  cut,  the  model  is  applicable  for  any 
wind  direction,  highway  orientation,  and  recep- 
tor location.  The  model  was  developed  for 
situations  in  which  horizontal  wind  flow  occurs. 
The  model  cannot  consider  complex  terrain  or 
large  obstructions  to  the  flow  such  as  buildings 
or  large  trees.  An  interactive  version  of  the 
computer  model  is  available  on  Environmental 
Protection  Agency's  Users'  Network  for  Applied 
Modeling  of  Air  Pollution  (UNAMAP).

A  four-year  study  of  two  irrigation  scheduling 
methods  and  application  rates  was  conducted 
to  determine  more  efficient  uses  of  supplemen- 
tal water  in  a  humid  climate.  One  model  based 
the  decision  to  irrigate  on  weather  forecast  and 
soil  moisture  conditions;  the  other,  irrigation  by 
demand,  based  on  soil  moisture  conditions 
only.  Two  application  rates  of  0.13  in/hr  (low) 
and  0.43  or  0.7  in/hr  (high)  were  used.  A  com- 
puter program  was  developed  to  calculate  soil 
moisture  and  predict  irrigation  needs  in  the 
forecast  scheduling  model.  A  0.5  probability  of 
rainfall  greater  than  0.5  inch  was  the  lower  limit. 
The  weather  forecast  also  provided  the  basis  of 
deciding  how  much  rainfall  would  be  included 
in  the  soil  moisture  balance.  The  method  of  ir- 
rigation by  demand  improved  production  160 
lbs.  of  seed  cotton  per  acre  for  each  inch  of 
water  applied.  Simulation  studies  following  the 
field  experiment  supported  the  results  of  the 
field  study.

develop  a  numerical  model  to  accurately  calcu- 
late the  trajectories  and  concentrations  of  reac- 
tive pollutants  emitted  from  localized  sources. 
The  numerical  model  employs  the  solution  of 


the  full  three-dimensional  Navier-Stokes  equa- 
tions along  with  the  solution  of  the  species  den- 
sity equation  by  summing  over  Lagrangian 
mass  points.  The  mass  points  are  transported 
by  the  mean  wind  field  and  moved  with  a  ran- 
dom walk  technique  that  simulates  the  turbu- 
lent diffusion.  The  effect  of  chemical  reactions 
are  modeled  by  reweighing  the  Lagrangian 
mass  points.  The  equations  are  solved  for  re- 
gions of  space  where  terrain  features  or 
buildings  may  cause  strong  distortions  in  the 
flow  field.  The  numerical  techniques  are 
verified  by  comparisons  with  analytic  formulas, 
including  the  boundary  layer  above  a  plate  and 
the  Gaussian  plume.  The  method  was  used  to 
calculate  photochemically  reacting  plumes 
using  a  simplified  inorganic  photochemical 
reaction  model.  Portions  of  this  document  are

perpressure  balloon  system  manufactured  from 
a  homogeneous,  isotropic,  elastic  film  suffi- 
ciently pressurized  to  prevent  geometric  insta- 
bilities. A  computational  model  of  the  problem 
was  established  in  the  area  of  load  attachment 
by  considering  a  rectangular  region  subjected 
only  to  an  in-plane  load  at  the  corner  and 
neglecting  any  effects  of  curvature.  The  grid 
size  is  sufficient  to  obtain  detailed  stress  dis- 
tributions in  and  around  seams  and  load 
patches.  Results  are  presented  for  two  particu- 
lar load  patches  as  well  as  the  stresses  as- 
sociated with  three  different  seam  to  film  stiff- 
ness ratios.  As  expected  the  results  indicated 
the  most  highly  stressed  region  to  be  in  the 
vicinity  of  load  introduction.  The  magnitude  of 
these  stresses  is  acceptable  but  dependent  on 
the  payload  being  supported  uniformly  by  all 
load  lines.  The  results  also  indicate  that  some 
load  is  retained  in  the  seam,  the  amount  depen- 
dent on  the  ratio  of  seam  to  film  stiffness.

An  advanced  generalized  urban  air  quality 
model  (IBMAQ-2)  is  developed  based  on  the 
theory  utilized  in  an  existing  model  (IBMAQ-1) 
as  prescribed  in  Ref.  1.  The  model,  based  on 
numerical  integration  of  the  concentration 
equation,  computes  temporal  and  three-dimen- 
sional spatial  concentration  distributions 
resulting  from  specified  urban  point  and  area 
sources  by  using  NEDS  (National  Emission 
Data  System)  and  simulated  RAMS  (Regional 
Air  Monitoring  System)  data.  The  UTM 
(Universal  Transverse  Metric)  coordinates  are 
used  in  all  geographical,  source  emission,  and 
monitoring  data.  A  new  method  to  incorporate 
point  sources  into  the  grid  computtion  is 
developed  by  using  a  Lagrange  trajectory 
method.  Many  model  options  are  provided 
which  enable  users  to  study  conveniently  the 
significant  effects  which  these  options  have  on 
the  final  concentration  distributions.  The  pro- 
gram description  is  included  to  provide  a  guide 
for  users.  The  program  is  constructed  in  a 
modular  form  which  allows  users  to  change  or 
improve  each  component  conveniently.  The 
input  auxiliary  model,  which  processes  geo- 
graphical, source  emission,  and  monitoring 
data,  is  also  included.

This  report  describes  the  refinement  of  a 
mesoscale  photochemical  air  quality  simulation 
model  through  studies  of  selected  chemical 
and  meteorological  phenomena  that  contribute 
to  air  pollution.  The  chemistry  activities 
focused  on  the  design  of  an  automatic  com- 
puter program  for  evaluating  kinetic 
mechanisms,  the  improvement  of  a 
photochemical  mechanism  for  incorporation  in 
mesoscale  models,  and  the  development  of  a 
chemical  mechanism  for  describing  S02  oxida- 
tion.  The   meteorology   studies  examined   the 


sensitivity  of  the  model  to  the  inclusion  of  wind 
shear,  algorithms  for  deriving  mass-consistent 
wind  fields,  and  the  treatment  of  turbulent  dif- 
fusivities  and  elevated  inversion  layers.  Alterna- 
tive numerical  techniques  for  solving  the  ad- 
vection/diffusion  equation  in  grid  models  are 
evaluated,  including  various  finite  difference, 
particle-in-cell,  and  finite  element  methods,  in 
an  attempt  to  find  a  suitable  methodology  for 
accurately  calculating  the  horizontal  transport 
of  pollutants.  Finally,  the  report  considers  the 
problem  of  multiday  model  usage  and  presents 
results  from  a  two-day  CO  simulation  for  the

This  report  develops  mathematical  techniques 
that  influence  the  development  of  urban  air  pol- 
lution but  are  not  resolvable  by  grid  networks 
used  in  airshed  simulation  models.  These 
phenomena  include  turbulence-generated 
fluxes  of  pollutants,  turbulence-induced  fluc- 
tuations in  the  contaminant  concentrations, 
and  subgrid-scale  variations  in  the  mean  con- 
centration distribution.  In  addition,  the  report 
examines  the  problem  of  resolving  the  spatial 
details  that  exist  in  the  mean  concentration 
fields  in  the  vicinity  of  point  and  line  sources. 
The  analysis  concludes  with  a  discussion  of  the

In  this  study  the  physical  processes  producing

author  chose  the  total  vertical  velocity  at  85

synoptic  activity.  A  diagnostic  3-D  atmospheric 
model  from  which  the  total  vertical  velocity 
from  6  physical  processes  may  be  computed  is 
designed  and  validated.  These  processes  are: 
the     differential     advection     of     vorticity,    the

thickness  advection,  the  release  of  latent  heat, 
the  effects  of  the  surface  enthalpy  flux,  and  the 
influence  of  friction  and  orography  at  the  sur- 
face. By  partitionment  of  this  diagnostic  model 
(the  omega  equation)  into  the  component  verti- 
cal velocities  the  magnitude  and  relative  im- 
portance of  each  process  may  be  determined. 
The  significance  of  each  physical  mechanism  is 
examined  at  48  h  intervals  throughout  the  his- 
tory of  a  mid-latitude  depression  system  which 
enters  the  region  as  a  developing  cyclone  on 
July  13,  1973  and  leaves  on  July  22  as  a  stag- 
nant vortex.

In  the  winter  months  of  Fairbanks,  Alaska,  a 
highly  stable  air  temperature  inversion  creates 
high  levels  of  carbon  monoxide  (CO)  concen- 
trations. As  an  aid  to  understanding  this 
problem,  a  CO  transport  computer  model  has 
been  created  which  provides  a  useful  tool  when 
used  in  conjunction  with  other  measurement 
and  analytic  studies  of  traffic,  meteorology, 
emissions  control,  zoning,  and  parking 
management.  The  model  is  completely  docu- 
mented and  illustrated  with  several  examples. 
Named  ACOSP  (Atmospheric  CO  Simulation 
Program),  it  predicts  expected  CO  concentra- 
tions within  a  specific  geographic  area  for  a 
defined  set  of  CO  sources.  At  the  present  time, 
the  model  is  programmed  to  consider  automo- 
bile emissions  as  the  major  CO  source  and  may 
include  estimates  of  stationary  sources.  The 
model  is  coded  for  computer  solution  in  the 
FORTRAN  programming  language  and  uses  the 
finite-element  method  of  numerical  solution  of 
the  basic  convective-diffusion  equations. 
Although  it  has  a  potential  for  real-time  analysis 
and  control,  at  the  present  time  the  model  will 
be  most  valuable  for  investigating  and  un- 
derstanding the  physical  processes  which  are 
responsible  for  high  CO  levels  and  for  testing 
remedial  control  measures  at  high  speed  and 
low  cost.

A  review  of  recently  reported  cooling  tower 
plume  models  yields  none  that  is  universally  ac- 
cepted. The  entrainment  and  drag  mechanisms 
and  the  effect  of  moisture  on  the  plume  trajec- 
tory are  phenomena  which  are  treated  dif- 
ferently by  various  investigators.  In  order  to 
better  understand  these  phenomena,  a  simple 
numerical  scheme  is  developed  which  can 
readily  be  used  to  evaluate  different  entrain- 
ment and  drag  assumptions.  Preliminary  results 
indicate  that  in  moderate  winds  most  of  the  en- 
trainment due  to  wind  can  be  accounted  for  by 
the  direct  impingement  of  the  wind  on  the 
plume  path.  Initially,  the  pressure  difference 
across  the  plume  is  found  to  produce  a  sub- 


stantial drag  force.  Thus,  it  is  likely  that  a  cer- 
tain portion  of  the  plume  bending  is  due  to 
these  pressure  forces,  and  artificially  increas- 
ing wind  entrainment  to  fit  experimental  data  is 
unnecessary.

The  numerical  solution  of  elliptic  partial  dif-

minimal  storage.  This  report  describes  seven 
Fortran  subroutines  and  contains  an  appendix 
dealing  with  solutions  of  linear  systems  of 
equations.  Five  subroutines  solve  a  Helmholtz 
equation  in  various  coordinate  systems;  they 
solve  two-dimensional  problems,  but  can  be 
adapted  for  use  in  three-dimensional  problems. 
The  other  two  subroutines  can  solve  a  more 
general  class  of  equation.

Regional  air  quality  studies  and  photochemical 
simulation  models  require  the  description  of 
wind  flow  patterns  for  specific  hours  of  various 
meteorological  regimes.  An  interdisciplinary 
team  that  includes  a  meteorologist,  and  air  pol- 
lution modeler,  an  environmental  planner,  and 
an  air  quality  engineer  can  use  plots  of  wind 
vectors  to  design  a  network  of  wind  monitoring 
stations.  Along  with  user  instructions,  input 
forms,  and  a  computer  program,  an  approach 
for  conducting  a  wind  flow  field  analysis  is 
presented.

A  three-year  record  of  monthly  precipitation 
from  a  10-station  National  Weather  Service  net- 
work, from  a  27-station  network  operated  by 
Thornthwaite  Associates,  and  from  the  com- 
bined 37-station  network  located  in  a  two- 
county  area  in  southern  New  Jersey  was  used 
to:  (1)  Evaluate  alternative  network  densities  for 
estimating  precipitation  for  water  resources 
purposes;  (2)  evaluate  several  different 
methods  of  estimating  areal  average  precipita- 
tion over  a  region;  and  (3)  determine  the  relia- 
bility of  estimated  patterns  of  precipitation  as 
network  density  changes.  Only  very  small  dif- 
ferences in  monthly  areal  average  precipitation 
were  found  using  three  different  estimating 
techniques— arithmetic  averaging  of  station 
values,  weighting  of  point  observations  by  con- 
struction of  Thiessen  polygons,  and  by  evalua- 
tion of  isohyetal  patterns  drawn  by  a  SYMAP

A  modification  of  a  previously  developed  com-

This  research  program  comprised  a  com-

regimes  on  the  western  shore  of  Lake  Michigan 
and  their  effect  upon  air  pollution  dispersion 
and  transport.  It  is  felt  that  the  results  are  ap- 
plicable in  a  generic  way  to  other  mid-latitude 
coastal  zones.  Continuous  fumigation  from 
elevated  sources  in  shoreline  zones  during  sta- 
ble daytime  onshore  flow  was  intensively  in- 
vestigated by  a  large  scale  field  program.  A 
model  was  proposed,  constructed,  validated 
and  calibrated.  It  was  shown  that  the  fumiga- 
tion spot,  while  causing  very  high  surface  S02 
concentrations,  was  so  highly  mobile  as  to 
generally  reduce  dosages  below  the  three-hour 
standard  (at  least  for  the  plants  studied).  An  in- 
tensive case  study  of  a  lake  breeze  was  per- 
formed. Data  were  used  as  input  to  a  Kinematic

mesoscale  trajectories  for  pollutants  released 
within  the  coastal  zone.  Both  mesoscale  and 
synoptic  scale  transport  of  photochemical  oxi- 
dants were  found  to  be  a  significant  problem  in 
the  Milwaukee  area.

In  the  radar  method  most  widely  used  to  locate 
and  measure  precipitation  within  thun- 
derstorms, a  single  radar  measures  the  reflec- 
tivity factor  of  the  hydrometeors.  This 
technique  is  accurate  only  under  certain  cir- 
cumstances, such  as  when  the  precipitation 
consists  of  rain.  But  when  hail  is  present  and 
the  radar  reflectivity  factors  due  to  rain  and  hail 
are  approximately  equal,  the  results  are  inaccu- 
rate. With  a  dual-wavelength  X-  and  S-band 
radar  (XSR),  X-band  microwave  attenuation  is 
determined  and  then  particle  precipitation  rate 
is  estimated.  Quantities  so  derived  appear  inde- 
pendent of  large  precipitation  rates.  Eccles 
(1975)  has  proposed  observational  and  numeri- 
cal techniques  to  recognize  X-band  attenuation 
by  precipitation  particles.  To  test  the  numerical 
technique,  we  correlated  the  derived  precipita- 
tion rate  and  total  precipitation  depth  with 
ground  measurements  from  northern  Colorado. 
Four  cases  were  considered  in  the  presence 
and  absence  of  hail:  light  and  heavy  precipita- 
tion rates  and  small  and  large  total  water 
deposition.  The  XSR  gives  better  estimates  for 
heavy  precipitation  rates  and  for  large  total 
water  deposition,  both  with  and  without  hail. 
The  single  radar  method  is  accurate  for  light 
precipitation  without  hail.

This  report  documents  the  development  of  an 
objective  analysis  program  for  the  mesoscale 
gridding  of  wind  and  temperature  for  the  Re- 
gional Air  Pollution  Study  being  conducted  in 
St.  Louis  by  the  Environmental  Protection 
Agency.  The  program  is  designed  to  produce  a 
5-km  spaced  horizontal  grid  analysis  from  a 
distribution  of  observations  which  are  sparse  at 
the  boundaries  of  the  grid  and  dense  near  the 
center.  An  iterative  scan  procedure  is  used  suc- 
cessively to  correct  an  initial  guess  field  until 
the  analysis  agrees  reasonably  well  with  obser- 
vations. A  procedure  is  used  where  widely 
spaced  observations  and  a  large  scan  radius 
are  first  used  to  approximate  the  field.  This  is 
successively  followed  by  the  addition  of  more 
observational  data  and  reduction  in  scan  radius 
until  the  field  converges  to  the  desired  analysis 
(usually  five  iterations  are  required).  This 
procedure  of  simultaneously  adding  more  data 
and  shrinking  the  scan  radius  insures  that  the 
small-scale  variability  in  areas  of  dense  obser- 
vations does  not  propagate  into  the  surround- 
ing areas  where  there  are  few  data.  The  special 
problems  of  producing  three-dimensional 
fields  of  gridded  data  from  the  observation  net- 
work are  discussed.  They  include  the  incon- 
sistency of  the  surface  and  upper  air  observa- 
tion networks,  the  non-uniform  density  of  the 
basic  observing  network,  and  the  difficulty  of 
producing  a  reliable  analysis  when  data  from 
one  or  more  key  stations  are  missing.

A  computer  program  has  been  created  and  is 
described  herein  which  employs  the  theoretical 
formulation  of  the  photolytic  rate  constant  to 
calculate  these  rate  constants  for  specific 
chemical  species  over  a  diurnal  time  period  in 
clear-sky  conditions.  A  user  of  the  program 
must  specify  the  date,  time  and  location  for 
which  the  rate  constants  are  desired.  With  this 
information  and  specific  data  on  zenith  angles, 
solar  irradiance,  and  species  characteristics  of 
absorption  cross-sections  and  primary  quan- 
tum yields,  which  are  provided  in  the  program 
package,  the  computer  program  generates  a 
diurnal  range  of  photolytic  rate  constants  for 
each  species.  The  species  included  are  N02, 
03,  HONO,  HON02,  H2CO,  CH3CHO,  and  H202. 
The  appendices  to  this  report  contain  program 
and  data  listings  as  well  as  a  User's  Guide  to 
program  operation.  The  program-generated 
photolytic  rate  constants  for  N02  are  compared 
to  direct  measurements  of  this  quantity  as 
taken  at  Research  Triangle  Park,  N.C.  during 
April  1975.  The  two  methods  are  generally  in 
close  agreement  after  the  theoretically  com- 
puted rate  constants  are  scaled  by  a  simplistic 
method  for  the  compensation  of  solar  radiation 
attention  by  clouds.

This  report  discusses  the  application  of  objec- 
tive analysis  techniques  to  the  computation  of 
trajectories  from  surface  wind  observations  of 
the  Regional  Air  Pollution  Study  in  St.  Louis. 
Trajectories  were  computed  over  a  100-kilome- 
ter square  grid  centered  on  St.  Louis  for  two  5- 
hour  periods  during  July  1975.  The  variability  of 
the  surface  wind  field  was  investigated  by  ex- 
amining the  temporal  and  spatial  variability  of 
computed  trajectories.  Also,  the  sensitivity  of 
the  computed  trajectories  to  the  amount  of  data 
employed  in  the  analysis  was  examined  in  some 
detail.  The  results  showed  a  general  lack  of 
sensitivity  of  the  computed  trajectories  to  a  sin- 
gle missing  observation.  However,  computed 
trajectories  were  very  sensitive  to  missing  ad- 
jacent observations.  In  addition  to  the  trajectory 
analysis,  a  set  of  tapes  containing  gridded 
winds  and  temperatures  for  the  St.  Louis  area 
were  generated.

tralian Omega  station  will  not  yet  be  completed. 
The  wind  accuracies  are  computed  for  a  13.6 
kHz  Omega  signal  between  30  degrees  N  and  30 
degrees  S  latitudes  for  local  noon  and  midnight 
in  January.  The  effect  of  Australia  is  clearly  il- 
lustrated. The  results  are  compared  with  data 
from  Majuro  Atoll  in  the  Marshall  Islands.  Ob- 
servations near  local  noon  are  shown  to  pro- 
vide the  greatest  accuracy.  The  FGGE  require- 
ment for  2  m/s  accuracy  will  be  met  in  substan- 
tial areas  of  the  tropical  Pacific  and  Atlantic 
Oceans  at  local  noon.  The  Indian  Ocean  region 
will  suffer  large  errors  south  of  the  equator 
without  Australia.  At  local  midnight,  when  sta- 
tions with  potential  modal  interference  are  not 
used  in  the  wind  computation,  the  regions  of 
acceptable  wind  errors  are  decreased.

This  report  is  the  result  of  research  into  new 
concepts  of  remote  sensing  of  the  atmosphere 
and  includes  a  literature  survey  of  the  theory 
and  practical  application  of  atmospheric 
sounding  using  acoustic  methods.  The  'state  of 
the  art'  has  been  advanced  in  that  a  new  type  of 
system  was  designed,  fabricated,  and  tested 
using  modern  digital  methods.  The  major  ad- 
vances of  replacing  the  typically  troublesome 
facsimile  recorder  with  a  dot-matrix  line  printer 
using  special  characters  called  'tonels'  and  the 
development  of  a  new  and  novel  method  of 
digital  Doppler  signal  processing  using  a  real 
covariance  technique,  is  presented  in  detail. 
The  ecosonde  is  capable  of  monitoring  and  dis- 
playing in  real  time  the  temperature  fluctua- 
tions, turbulent  velocity  inhomogeneities,  and 
vertical  wind  profile  of  the  planetary  boundary 
layer  to  a  height  of  680  meters  and  includes  a 
microcomputer,  a  high-speed  line  printer,  and 
various  author-designed  and-constructed 
digital  and  analog  circuits.  User  control  of  vari- 
ous system  parameters  and  a  wide  choice  of 
display  possibilities  make  this  a  versatile  and 
desirable  atmospheric  research  tool.

An  analysis  of  the  DIFKIN  photochemical  model 
characteristics  and  sensitivities  to  various  input 
parameters  is  presented.  DIFKIN  is  a  trajectory 
type  photochemical  air  quality  simulation 
model.  The  most  sensitive  input  parameters  to 
Ozone  production  are  initial  concentrations, 
reaction  rate  constants,  and  inversion  base 
height.  The  ratio  of  Reactive  Hydrocarbons  to 
Nitric  Oxide  emissions  are  far  more  important 
in  determining  Ozone  production  than  the  ac- 
tual magnitudes  for  emissions.  The  DIFKIN 
model  is  most  applicable  to  projects  that  result 
in  changes  in  emissions  in  a  few  adjacent  grid 
cells  rather  than  widespread  changes  in  emis- 
sions over  an  air  basin.  Five  or  more  trajectories 
should  be  used  to  determine  air  quality  impacts 
of  a  particular  project.

Two  new  computer  programs  are  described. 
One  is  an  echo  isolation  and  tracking  program 
called  PEAKS,  which  fits  a  bivariate  normal  dis- 
tribution to  each  echo,  and  also  to  each  relative 
maximum  in  rain  rate  within  each  echo's 
perimeter.  This  program  is  based  upon  different 
principles  than  its  predecessor  (TRACK)  and 
appears  to  make  fewer  errors  in  judgment.  After 
a  whole  day's  data  has  been  processed  with  the 
tracking  program,  all  tracked  echo  information 
is  transferred  to  the  second  computer  program 
named  STATS.  It  formulates  hourly  and  whole 
day  summaries  of  South  Florida  echo  areas  and 
rain  volumes  for  all  combinations  of  location 
(land/sea/both)  and  status 

(unmerged/merged/all).  Also,  a  whole  day  of 
tracked  echo  data  is  accumulated  and  results 
are  tabulated  for  echo  areas  versus  rain 
volumes  within  quartiles  of  growth  tendency. 
Regression  equations  for  these  combinations 
are  created  and  histograms  can  be  displayed. 
Examples  depict  results  from  the  two  programs 
using  the  enlarged  array.  Appendices  provide 
the  complete  Fortran  code  for  the  entire  en- 
semble of  Nheml  software  for  processing

Control  of  solar  light  and  heat  to  develop  the 
proper  growth  environment  is  a  desirable  goal 
in  forest  management.  The  amount  of  sunlight 
and  heat  reaching  the  surface  is  affected  by 
shadows  cast  by  nearby  objects,  including 
trees.  In  timbered  areas,  the  type  of  forest 
management  practiced  can  help  develop 
desired  microclimates.  The  results  depend  on 
the  size  and  orientation  of  openings  created 
and  on  the  shade  cast  by  surrounding  vegeta- 
tion. A  computerized  method  to  calculate  the 
extent  of  boundary  shading  for  any  combina- 
tion of  date,  slope,  and  aspect  between  23.45 
degrees  N.  latitude  and  50  degrees  N.  latitude  is 
described.  For  those  who  do  not  wish  to 
develop  their  own,  a  set  of  shadow-length  ta- 
bles is  available  upon  request.  These  may  be 
secured  as  an  entire  set  or  by  individual 
latitudes.  They  provide  coverage  for  the  con- 


71 


tiguous  United  States  in  increments  of  2  from 
36  degrees  N.  latitude  to  50  degrees  N.  latitude. 
By  extrapolation,  the  tables  can  be  used  from 
the  Mexican  to  the  Canadian  border.

The  delta-Eddington  approximation  of  Joseph, 
Wiscombe,  and  Weinman  (1976)  is  extended  to 
an  atmosphere  divided  up  by  internal  levels  into 
homogeneous  layers.  Flux  continuity  is  en- 
forced at  each  level,  leading,  as  the  mathemati- 
cal essence  of  the  problem,  to  a  penta-diagonal 
system  of  linear  equations  for  certain  unknown 
constants.  Fluxes  (up,  direct  down,  diffuse 
down,  and  net)  are  then  predicted  at  each  level. 
Unphysical  results  of  the  model  are  examined 
in  detail.  potential  numerical  instabilities  in  the 
solution  are  noted  and  corrected,  and  an  ex- 
tremely fast,  well-documented  computer  code 
resulting  from  this  analysis  is  described  and 
listed.  Actual  computed  fluxes  are  given  for 
several  test  problems.

A  possible  short  term  oxidant  control  strategy 
would  involve  (1)  reduction  of  overall  reactive 
hydrocarbon  and  NOx  emissions,  (2)  restriction 
of  morning  commuter  traffic  and  (3)  a  shift  of 
emissions  into  the  evening  and  nighttime 
photochemically  inactive  hours.  These 
represent  the  emissions  alterations  which 
usually  mark  the  change  from  the  weekdays  to 
weekends,  and  can  be  evaluated  in  advance 
from  statislical  studies  of  past  weekday- 
weekend  differences  in  monitored  oxidant 
levels.  This  study  uses  data  from  the  South 
Coast  Air  Basin  to  demonstrate  that  there  exists 
a  definable  subset  of  conditions  under  which 
switching  to  weekend  emissions  would  signifi- 
cantly decrease  average  oxidant  levels  both 
one  and  two  days  into  the  future.  This  strategy 
works  best  under  conditions  of  particularly  ad- 
verse oxidant  levels.

In  order  for  transportation  planners  and  en-

proposed  project,  mathematical  means  are 
required  to  describe  the  dispersion  of  air  pollu- 
tants from  a  line  source.  CALINE2,  the  Califor- 
nia Line  Source  Dispersion  Model,  is  presented 
and  discussed  as  one  such  mathematical  ap- 
proach. CALINE2  is  based  on  the  generalized 
Gaussian  dispersion  theory,  and  simulates  the 
dispersion  of  carbon  monoxide  from  a  uniform 
line  source.  A  sensitivity  analysis  of  the  model 
relates  the  behavior  of  its  predictions  as  a  func- 
tion of  the  input  parameters.  A  preliminary

The  development  and  testing  of  a  method  for

estimate  of  the  mean  areal  precipitation  over

precipitation  observation.  The  accuracy  of  the 
average  hinges  upon  the  ability  to  extrapolate

the  sounding  data  were  good  but  was  weak

for  pattern  changes  with  wind  direction.

The  Commonwealth  Bureau  of  Meteorology 
has  established  and  operates  a  network  of  sta- 
tions throughout  Australia  measuring  solar 
radiation.  The  network  was  established  early  in 
1968  and,  with  subsequent  additions,  consists 
of  some  20  stations  recording  total  global 
horizontal  solar  radiation  integrated  over  half- 
hourly  periocis;  some  of  these  stations  also 
record  diffuse  horizontal  solar  radiation  over 
the  same  periods.  These  data  are  processed 
and  stored  on  magnetic  tape  in  the  Computer 
Section  of  the  Meteorological  Bureau  in  Mel- 
bourne. A  complete  copy  of  the  tape  of  global 
horizontal  solar  radiation  has  been  reproduced 
in  a  form  compatible  with  the  C.S.I.R..O. 
CYBER  7600  computer.  This  report  describes 
the  information  stored  on  the  C.S.I.R.O.  mag- 
netic tape  and  the  method  of  retrieving  that  in- 
formation. (ERA  citation  01 :018888)

The  deployment  of  high-energy  lasers  against 
moving  targets  is  almost  always  noncoplanar. 
This  noncoplanarity  creates  a  vertical  wind 
component  in  the  transverse  plane  that  causes 
the  effective  wind  vector  to  rotate  continuously. 
All  propagation  codes  that  have  been 
developed  in  the  past  have  been  based  on  the 
assumption  of  a  purely  horizontal  wind.  The 
scenario  capability  of  the  Four-D  code  has  now 
been  generalized  from  the  previous  coplanar 
version,  which  assumed  a  moving  laser  plat- 
form, a  target  on  a  collision  course  with  the 
platform,  and  an  arbitrarily  oriented  coplanar 
wind.  Currently  the  laser  can  be  displaced  to 
any  height  above  the  platform,  and  the  scenario 
plane  can  be  aribitrarily  oriented  with  respect  to 
the  horizon.  The  scenario  routine  returns  to  the 
hydrodynamics  routine  of  the  code  a  transverse 
wind  velocity  vector  of  varying  magnitude  and 
orientation.  The  hydrodynamics  routine  of  the 
Four-D  code  is  now  capable  of  treating  both 
CW  and  multipulse  steady  state  sources  with 
winds  of  arbitrary  magnitude  and  direction  rela- 
tive to  the  x-axis.  A  complete  time-dependent 
capability  for  arbitrary  wind  directions  will  be 
completed  some  time  in  the  near  future.  (ERA

is  modeled  in  the  2-D  atmospheric  transport

the  eddy  diffusion  approximation  for  short-term 
fluctuations  in  the  velocity,  other  simplifying 
approximations,  the  geometric  grid,  the  dif-

the  grid.  The  assumption  of  a  constant  vertical 
density  distribution  was  used  to  derive  mass- 
consistent  forms  of  the  difference  equations. 
These  forms  eliminate  the  instabilities  and  un- 
realistic solutions  associated  with  specified 
wind  fields  which  are  not  exactly  mass-con- 
sistent. An  option  is  allowed  for  variable 
weighting  between  central  (second-order)  and 
upstream  (first-order)  forms  of  the  spatial  dif- 
ferencing of  the  advection  terms,  to  modulate 
phase  and  amplitude  errors  in  the  advection

PATRIC  is  a  transport  and  diffusion  code 
designed  to  calculate  the  three-dimensional 
distribution  of  atmospheric  pollutants  in  a 
given  space  and  time  varying  flow  field.  It  is 
based  on  the  particle-in-cell  model  in  which  the 
pollutant  mass  or  activity  is  represented  by  the 
spacial  distribution  of  a  large  number  marker 
particles.  The  temporal  evolution  of  this  particle 
distribution  results  from  the  transport  of  each 
individual  marker  particle  due  to  advection  by 
the  mean  wind  and  diffusion  by  the  Gaussian 
formula.  The  code  is  capable  of  computing  in- 
stantaneous or  time-integrated  air  concentra- 
tions and  deposition  for  a  variety  of  instantane- 
ous or  continuous  sources,  including  inert  and 
radioactive  materials.  PATRIC  was  developed 
as  a  simplified  and  speeded-up  version  of  the 
Lawrence  Livermore  Laboratory  three-dimen- 
sional transport  and  diffusion  code  for  complex 
terrain  ADPIC.  PATRIC  computer  time  is  ap- 
proximately one  minute  for  every  24  hours 
modeled  which  makes  the  code  suitable  for  an- 
nual air  quality  assessments.  (ERA  citation

Time-Dependent  Propagation  of  High  Energy

A  general  time-dependent  three-space-dimen- 
sional propagation  code  is  described.  This 
code  is  capable  of  treating  the  propagation  of 
high  energy  laser  beams  through  the  at- 
mosphere in  the  presence  of  a  horizontal  wind 
and  turbulence  for  most  situations  of  interest. 
Possible  cases  are  propagation  of  cw  beams 
through  stagnation  zones,  multipulse  propaga- 
tion, including  the  self-consistent  treatment  of 
pulse  self-blooming,  and  propagation  involving 
transonic  slewing.  The  solution  of  the  Maxwell 
wave  equation  in  Fresnel  approximation  is  ob- 
tained by  means  of  a  discrete  Fourier  transform 
method,  which,  surprisingly,  gives  excellent 
results  for  diffraction  problems.  The  latter  pro- 
vide a  stringent  test  for  the  accuracy  of  any 
solution  method.  Considerable  use  is  also 
made  of  discrete  Fourier  transform  methods  in 
solving  the  hydrodynamic  equations.  The  treat- 
ment of  turbulence  is  based  on  the  generation 
of  random  phase  screens  at  each  calculation 
step  along  the  propagation  path.  In  a  time-de- 
pendent calculation  the  random  phase  screens 
can  be  either  made  to  move  with  the  wind  at  a 
given  propagation  position  or  generated  anew 
for  each  successive  time.  The  code  is  equipped 
with  a  general  scenario  routine  involving  a 
moving  laser  platform  as  well  as  target.  This 
routine  allows  the  code  to  treat  an  effective 
transverse  wind  velocity  that  varies  with  time  as 
well  as  axial  position  Thus  it  is  possible  to  take 
into  account  the  motion  of  the  stagnation  point 
in  treating  the  propagation  of  beams  through 
stagnation  zones.  The  code  is  equipped  with 
extensive  editing  facilities  which  generate  vari- 
ous averages,  contour  plots,  and  plots  of  quan- 
tities of  interest  as  a  function  of  time.  The  report 
also  contains  illustrative  examples  of  the  code's 
different  calculational  features.

This  report  summarizes  our  current  effort  and 
ideas  toward  the  development  of  a  model  for 
the  planetary  boundary  layer  using  the  finite 
element  technique.  As  an  initial  step,  the  finite 
element  methodology  is  applied  to  simpler  ver- 
sion of  the  boundary  layer  equations  given  by 
the  two-dimensional,  constant-property,  in- 
compressible conservation  equations  (Navier- 
Stokes  equations).  Solution  procedures  for 
both  the  steady-state  and  transient  equations 
are  discussed.  For  the  transient  problem,  a  vari- 
able time-step,  trapezoid-rule  algorithm  with 
dynamic  time-truncation  error  control  is 
presented.  The  resulting  system  of  nonlinear  al- 
gebraic equations  is  solved  by  a  Newton  itera- 
tion procedure  with  a  frontal  solution  scheme 
used  for  the  linear  set  of  equations.  The  need  to 
develop  a  suitable  linear  equation  solver,  with 
respect  to  minimization  of  computer  storage 
and  execution  costs,  particularly  for  large 
(three-dimensional)  finite  element  problems,  is 
also  discussed.  (ERA  citation  03:037946)

A  brief  description,  with  examples  of  usage,  is 
given  of  a  new  FORTRAN  package  called 
EPISODE,  for  the  numerical  solution  of  the  ini- 


tial-value problem  for  systems  of  ordinary  dif- 
ferential equations.  EPISODE  contains  both  a 
variable-step,  variable-order  implicit  Adams 
method  and  a  variable-step,  variable-order 
backward  differentiation  method.  Since  the 
user  may  select  either  of  these  methods  simply 
by  assigning  the  appropriate  value  to  a  method 
flag,  EPISODE  can  be  used  to  solve  either  stiff 
or  nonstiff  problems.  Similarly,  the  user  also 
selects  one  of  four  corrector  iteration  methods 
to  be  used.  EPISODE  was  motivated  by 
problems  in  atmospheric  modeling  at  LLL  in 
which  chemical  rate  constants  vary  with  time  in 
an  abrupt  diurnal  manner.  Examples  of  such 
problems,  and  others,  are  given  to  illustrate  the 
use  and  effectiveness  of  the  program.  Outside 
LLL  the  EPISODE  package  is  being  supplied  in 
double  precision,  but  contains  the  single  preci- 
sion version  imbedded  in  it.  Conversion  to  sin- 
gle precision  can  be  easily  done  with  a  con- 
verter subroutine,  supplied  with  the  package.
