    The Cold Weather Plume Study (CWPS) was a field measurement program carried
out in February 1981 under the joint sponsorship of the U.S. Environmental Protec-
tion Agency and the Electric Power Research Institute. Its objective was to generate
a data base suitable for quantitative analysis of the mesoscale physical dynamics and
SOa, NOa; chemistry of the plume of the 1320 MW coal-fired Kincaid power plant near
Springfield, IL. The data base was intended to complement similar measurements made
by other EPA and EPRI studies in the same region during other seasons. Measurements
included in-situ chemical measurements from two instrumented aircraft, remote-sensing
lidar measurements from an aircraft, meteorological measurements from a surface sta-
tion, two met towers, and from vertical soundings. This report provides a brief overview
of the measurement platforms, the measured  parameters, and the daily  experiments,
and describes and documents  the data base available on magnetic tapes and in hard
copy form.

                           EXECUTIVE SUMMARY

    A Cold Weather Plume Study (CWPS) was carried out from a St. Louis base in
February, 1981 under the joint sponsorship of the Environmental Protection Agency
(EPA) and the Electric Power Research Institute, Inc. (EPRI). The main objective of
the field measurement program was to generate a data base appropriate for quantitative
characterization of the mesoscale transport and chemical transformations of SOX and
NOa; in the plume of the 1320 MW, coal-fired Kincaid power plant near Springfield, IL,
under winter conditions. The measurements included in-situ airborne chemical sam-
pling in the plume and its background, as well as a variety of meteorological measure-
ments  characterizing the PBL structure and dynamics of the wind, temperature and
humidity fields. Previous extensive power plant plume measurements had been carried
out in power plant plumes in the same region in summer and spring periods. Analyses
of the data of these previous studies had already yielded valuable quantitative empirical
descriptions of the plume atmospheric transmission processes, particularly for SOX. A
more specific objective of the winter study was to test the validity of such quantitative
parameterizations under winter conditions  and, if necessary, to revise the formulations
to make  them seasonally more general. Another important aspect of the winter study
was a more balanced emphasis on SOa as well as NOX atmospheric chemistry. This re-
port overviews the measurement program,  identifies other reports which contain more
detailed program description and data, and most importantly, describes and documents
the formal overall centralized data base of  CWPS.
     There were two teams of participating groups  in the field program, one supported
by EPA  and the other by  EPRI. Each participating group had a specific role  in the
study, yet all measurements of a given daily mission were performed within the context
of a co-ordinated overall mission plan.  The two teams shared the same overall pro-
gram objectives, but emphasized different  specific objectives.  The EPA team's focus
was  more on SOX chemistry, while the EPRI team placed greater emphasis on NO*
chemistry. Overall, the measurement strategy was focused on detailed aircraft chemical
sampling in the plume over a mesoscale range; two primary sampling aircraft were typi-
cally deployed in each experiment.  Supporting measurements included stack sampling,
monitoring of ambient meteorological parameters, and remote sensing of PBL aerosol
structure and dynamics.

    The in-situ aircraft measurements included continuous monitoring of gas concen-
trations (SO2, NO, NOs, N-rotai, O3), aerosol parameters (ANC, Charge, B8Cat)i mete-
orological variables (temperature, humidity, pressure, turbulence, solar radiation), and
navigational parameters (altitude, VOR, DME). Integrated filter samples were collected
and analysed for aerosol sulfate, nitrate, chloride and ammonium; for gaseous ammonia
and nitric acid; and for elemental composition. Automatic bag samples were also col-
lected nearly instantaneously at regular intervals and analysed on-line for aerosol size
distribution.  In addition, integrated samples were collected in Teflon bags and analysed
daily at a ground laboratory for detailed speciation of organic  vapors, including PAN.

    Stack measurements of S02, NO, O2 and exit gas velocity and  temperature were
made at Kincaid. Meteorological support measurements included measurements near
the power plant by ROCKWELL, and at downwind locations near prevailing plume
transport trajectory by AV.  Measurements near the power plant were made at a sur-
face station (pressure,  temperature, net/solar/sky radiation, cloud cover and precipi-
tation), from 10 and 100m meteorological towers (mean temperature, dewpoint, wind
speed/direction, and u,v,w components of the wind field), and from tracked T-sondes
(T, wind speed/direction). Downwind meteorological measurements by AV included
frequent pibal (wind speed/  direction) and airsonde (temperature and relative humid-
ity) soundings during the  experiment periods. Synoptic weather data were gathered

and  interpreted by SRI at the local NWS forecasting office.  SRI provided weather
forecasts and summaries tailored to the needs of the daily missions.
     PBL and plume structure and dynamics were "visualized" by remote sensing of
atmospheric aerosol distribution based on lidar returns of aerosol backseattering mon-
itored in the lidar aircraft (EPA-LV) flying well above the PBL.
     The Kincaid power plant has  two generating units rated at 660 MW each, both
feeding  into a single 187 meter tall stack. During the CWPS period, however, one of
the units was inoperative.
     The field study period was 9-21 February,  1981. During this period, a total of six
independent field experiments were carried out  on five separate days (February 12, 13,
14, 16 and 20). There were two separate experiments on the 20th.  In four of these
experiments, both primary sampling aircraft (EMI and MRI) performed co-ordinated
measurements. In three separate missions, the two aircraft flew side-by-side to provide
data for cross-comparison. The first three experiments were conducted under very cold
daytime winter conditions. Ambient conditions were unseasonably warm during the
last  three experiments.  One  of these experiments was during the night. During the
first and the last experiments, the Kincaid plume was sampled within  the convective
daytime mixing layer; bulk plume transport was  in the  stable layers aloft during all
other sampling missions.  Plume background was fairly clean during all  field missions.
     Each participating group was responsible  for quality assurance, post-processing,
and  validation  of its own data. The final  data of the EPA team was centralized at the
WU-ME Special Studies Data Center at Washington University in St. Louis. The data
of the EPRI team was centralized at Battelle, Columbus Labs.  The EPA and EPRI
data bases were formally exchanged in 1984. Subsequently, both these subsets of the
overall data base were reformatted and standardized into a single unified CWPS data
base at  our data center. All data files in this CWPS data base conform to the standard
STATE formats common also to three other data bases of major EPA-sponsored Studies
(MISTT, Tennessee Plume Study, and PEPE-NEROS). This report provides a full
documentation of the final CWPS  data base. Future distribution of the data base will
be administered by EPA.

    Electric power generating stations using coal and oil as fuel constitute a major
source of S0a and NOa emissions into the atmosphere of the eastern United States. At-
mospheric transmission processes (transport, transformation, removal) acting on these
emissions determine their atmospheric residence time, their contribution to ambient air
pollution, their range of transport, location of impact, and form of deposition. In the
past decade, many field studies have been carried out with the objective of quantitative
investigation of the mechanisms and  rates of the atmospheric transmission processes.
The vast majority of these field measurements were  carried out during the summer
season when the chemical transformation processes leading to the formation of noxious
secondary products from the precursor emissions are more rapid and secondary pol-
lutant levels (air concentrations and depostions)  are more pronounced.  Such summer
field studies include the EPA-sponsored Projects MISTT  (St. Louis, 1974-1976)  and
STATE-Tennessee Plume Study (Tennessee, 1978), and the EPRI-sponsored SURE
Plume Study (Indiana, Michigan, Mississippi, 1977) and the Plume Model  Validation
Study (PMV: Kincaid, IL, 1980).  In February 1981, EPA and EPRI jointly sponsored
the field program of the Cold Weather Plume Study  (CWPS). The measurements of
this study were made in plume of the Kincaid power plant.

    EPA's principal objectives in the interpretation of the CWPS data included char-
acterization of winter transport of tall-stack plumes, the quantitative  assessment of
mechanisms and rates of SO2-to-sulfate conversion in power plant plumes in winter,
and the testing of an empirical parameterization of plume sulfur conversion rate orig-
inally formulated based  on summer data.  EPRI's prime objectives were to study the
details of the NOX chemistry of the plume during near-field transport, to test a detailed
reactive plume model, and to extend the simple-terrain short-range plume dispersion
study of PMV to broader seasonal coverage. Such data analyses have been carried out
at WU for EPA and at BATTELLE for EPRI.

    Two detailed reports describe the CWPS measurement program: one is by EMI
(EMI, 1984)*, the EPA prime contractor for CWPS; the other is by BATTELLE (Bat-
telle,  1983), the EPRI prime contractor  for CWPS.  Both describe the full range of
CWPS measurements, but each is focused more on activities of its respective team.
Since these reports  adequately cover the details of the measurement program,  plat-
forms, data processing and validation, quality assurance, etc., this report contains only
a brief program overview and a description and documentation of the final data base.
Five hard copy data volumes, one for each of the five  mission days of CWPS, were
prepared in conjunction  with this report.  Each data volume  contains a daily meteoro-
logical summary, and graphical plots of complete meteorological and aircraft data (EMI
and MRI). The daily data volumes thus collectively contain a compilation of almost all
the available data of CWPS in graphical  or tabular form. The data volume contents
are described further in  chapter four, "CWPS Data Base".
    References are listed in section 4.1.

               2.  SUMMARY OF  CWPS MEASUREMENTS
 2.1 In-situ Aircraft Sampling

    Two  instrumented aircraft performed in-situ plume  and background  measure-
ments. They were the EMI and the MRI aircraft. Tables  2.1 and 2.2 summarize the
instrumentation packages of the two aircraft. The common parameters monitored in
the continuous mode in the two aircraft were: SO2, NO/NOX, O3, Aitken nuclei count,
aerosol charge, light scattering coefficient (B8cat), ambient and dew point temperatures,
aircraft altitude and the VOR/DME position co-ordinates. In addition, the MRI air-
craft also monitored broadband and UV solar radiation from an upward-looking sensor,
and small-scale atmospheric turbulence (expressed in terms of the turbulent energy dis-
sipation rate, e). The MRI NOX chemiluminescence analyzer was specially modified by
BATTELLE to measure NO, NT (=NO + NO2 + HNO3  + NO3 + 2N2O5 + PAN),
and NOX(=NT-HNO3).  The  difference (NT-NO*) is  reported in the data base as
HNOs. The EMI aircraft also had a fast response sulfur  monitor specially modified to
monitor continuously the particulate sulfur component  (5P).  The instrument opera-
tion, performance, and data for Sp have, however, been judged of unacceptable quality,
and have  been  excluded from the data base.  The absence of acceptable Sp data is a
critical shortcoming of the chemical data base of CWPS. Another critical shortcoming
of the CWPS data of EMI was due to the malfunction of the nephelometer (£8Cat)
in the first three EMI missions (Feb. 12, 13, 14).  A replacement was in place for the
last two experiments (Feb.  16,  20) and performed well.  The  data logger in the MRI
aircraft malfunctioned in the first mission (Feb. 12). However, most of the continuous
data were recorded on strip charts and were later digitized and incorporated into the
permanent data base.

    The  two aircraft  also made some aerosol  size distribution measurements.  The
EMI aircraft had an electrical  aerosol analyzer (EAA, for .0032 to 1 pm size range)
and a ROYCO  optical particle counter (OPC for .56-5.6  pm range). The data of these
measurements have not been processed and are not available in the current data base.
The MRI aircraft instrumentation package for aerosol size distribution measurements
is summarized in Table 2.3.

     Both aircraft also collected some time-integrated samples for post-facto chemical
analyses.  The EMI integrated sampling included a cyclone separator system for collec-
tion of fine aerosols (<3 pm), and a tungstic acid tube system for collection and later
analysis of gaseous and particulate ammonia and nitric acid. The filter sampling of
aerosols was on washed nylon filters (analysed for sulfate  and nitrate), and on prepared
cellulose nitrate filters (analysed for chloride).  The integrated sample collections and
analyses pertinent to the MRI aircraft sampling are outlined in Table 2.4. They include
bag samples for hydrocarbons  and PAN, and filter samples for inorganic gaseous and
aerosol species.

    The sampling missions and times for the two aircraft are summarized in Table 3.1.
Each aircraft had five flight missions, four being common to both aircraft. During three
of these common missions (viz. February 12, 16, 20), single-traverse, side-by-side and
simultaneous flights were made by the two aircraft for the purpose of inter-comparison
of data. Data plots showing such inter-comparison of common continuous monitors are
included in the EMI data volume (EMI, 1983).

                      2.2 Meteorological Measurements

    Meteorological support  for the program was  provided by three  organizations:
ROCKWELL,  AV and SRI. ROCKWELL'S measurements were made at a surface
station, from 10 m and 100 m meteorological towers, and from vertical soundings, all
at a site about  1 km east of the Kincaid power plant. The ROCKWELL measurements
and instrumentation are outlined in Table 2.5. The vertical soundings were based on T-
sondes which were tracked by double theodolites, and which measured vertical profiles
of temperature and wind speed and direction.
    Solar radiation is, of course, a crucial parameter for data analyses, for both disper-
sion and chemistry interpretations.  The only radiation data collected  directly  under
CWPS  auspices were at the ROCKWELL surface station at Kincaid, and the continu-
ous measurements of UV and broadband radiation in the MRI aircraft. Unfortunately,
good surface data were obtained only on February 20. Consequently, a substitute set of
total radiation data for the mission days was obtained  in the form of continuous strip
chart recordings made at the  Illinois State Water Survey (ISWS) facility in Champaign,
IL, about 80 km to the northeast of Kincaid. The ISWS  solar  radiation data for each
day were digitized by us, and have been incorporated into the CWPS data base.
    AV provided additional upper air soundings for the wind, temperature and hu-
midity vertical profiles in the PEL. A mobile minisonde platform was used to launch
pilot balloons equipped with pressure, temperature and relative humidity sensors. By
tracking the pilot balloon from a single theodolite,  vertical profiles of horizontal wind
speed and direction were also determined.  The AV minisonde was located at a different
downwind fixed site under the plume  trajectory for each mission.  The site was typi-
cally about 40-60 km downwind of Kincaid, the actual location being selected based on
the prevailing wind data obtained from the ROCKWELL soundings which commenced
shortly before the start of the aircraft mission. The AV site locations and pibal launch
periods are summarized in Table 2.6. Further details of the AV measurements and data
are contained in the AV data volume (AV, 1983).
     SRI provided meteorological support pertaining  to synoptic and  local  weather
review  and forecasting tailored to  the daily mission needs. An experienced weather
forecast meteorologist, utilizing the extensive resources of the local NWS weather fore-
cast office in St. Peters, MO, (near St. Louis) monitored the weather conditions and
provided frequent weather bulletins and forecasts to guide mission  planning and  exe-
cution. Some of the raw materials (weather maps, etc.)  used by SRI are included in
our daily data volumes (appended to this report). Also included  in those data vol-
umes are 3-hourly tabulations of pertinent data collected at the NWS surface weather

observation stations in about a 100 km radius of Kincaid.

                      2.3 Aircraft Lidar Measurements

    A two-frequency (I.R. and Green), downward-looking, airborne lidar system was
flown and operated by EPA-LV. The aircraft lidar typically flew at about 3 km altitude
in a pattern of cross-plume traverses at several downwind arcs. In normal operation,
the lidar emitted laser pulses downward and the  return signal, representing aerosol
backscattering, thus provided a  measure of  aerosol distribution below.  The  return
signals were recorded on magnetic tapes. The data provide vertical profiles of aerosol
concentration (at 3 m vertical resolution) at approximately 10 m horizontal resolution.
The lidar data provide a visual depiction of the PBL and plume aerosol structure and
dynamics with broad spatial coverage.

    The lidar aircraft flew missions on all five days.  The lidar data complement the
other aircraft data of all experiments except the last one during daytime on February 20.

                             2.4  Stack Sampling

    ROCKWELL  performed continuous stack sampling for stack 862, NO and Oj,
as well as continuous monitoring of stack exit temperature and velocity.  The single
187 m stack at Kincaid has an inner diameter of 9.0 meters. The measurements and
instrumentation for stack sampling are summarized in Table 2.5. The data are included
in the CWPS data base.

                            3. CWPS MISSIONS

    CWPS experiments were conducted on five separate days, viz. February 12, 13,
14, 16 and 20.  Table 3.1 summarizes the times, prevailing atmospheric  conditions,
and aircraft mission times for EMI, MRI and EPA-LV aircraft for all five days.  The
EMI aircraft flew on all five days; The MRI aircraft did not fly on February 14, but
flew a complete predawn mission on February 20 (the only night mission of CWPS)
preceding their full daytime mission on the same day. The lidar aircraft flew all missions
except the daytime mission of February 20. Plume transport was mostly in the elevated
stable layers in all but the first and the last experiments (February 12 and  20 daytime
experiments). In these two leading and trailing experiments, the plume was well-mixed
within the convective daytime mixing layer.  Plume background during all but one of
the experiments was fairly clean and dry.  On February 16, the PEL air became very
hazy  and foggy  during the course of the experiment.  However, except for a possible
brief  period of entrainment of a portion of the plume into  the upper portion of the
mixing layer on this day, the bulk of the plume transport was outside the very polluted
mixing layer.
    Typical winter conditions did not prevail during the entire CWPS period. During
the first week (including the experiments of Feb. 12,13,14), the ambient conditions were
colder than average for this time of year with snow on the ground. The second week
(including Feb.  16 and 20), however, was unseasonably warm, with daytime ground
level temperatures peaking above 15 C  (59°).
    Aircraft missions of the  five days  are summarized in the  form of flight outlines
and maps for the two in-situ aircraft, in Appendix Al. Table 3.2 summarizes the
participation of all platforms for all days. All times in the CWPS data  base are in
Central Standard Time (GST).

                           4. CWPS DATA BASE


    The data base of CWPS is summarized in Table 4.1.  The Table gives, for each
measurement platform, the measured parameters, temporal resolution of the data when
regular, and the form(s) in  which the  data are available.  In general,  the data base
exists in two forms—on magnetic tapes and in the form of reports and hard copy data
volumes.

    The magnetic tape data base is in  two parts—the aircraft raw data base, and the
final GDDB (General Distribution Data Base). The GDDB is the standardized final
user form of the data base on magnetic tapes. It includes all the validated data collected
in CWPS except the aircraft lidar data, and the EMI and MRI aircraft aerosol size
distribution data. The lidar  data on tapes are in raw form only, very voluminous, and
not expected  to be of interest to most users of CWPS data. The lidar hard copy data
volume contains a complete  and easily usable photographic presentation of the data.
Corresponding to each lidar  plume traverse, two photographs  (one for I.R. return and
one for Green return) give the entire picture of aerosol spatial distribution in grey scale
contrast. The aircraft raw data base  includes the raw data of  the lidar aircraft  as well
as of the two chemical sampling aircraft.

    In what follows, we describe the hard copy data base and the GDDB of  CWPS.

 4.1 Hard Copy Data Base of CWPS

    Besides this report and its appendices, there are two other detailed reports related
to CWPS. They are:

    1. EMI (July 1984): Cold Weather Plume Study, Final Report to EPA (Contract
No. 68-02-3411)

    2. Battelle, Columbus Labs (May 1983): Nitrogen Oxide Transformations in Power
Plant Plumes, Interim Report to EPRI (Research Project 1369-2)

    The above reports describe the EPA and EPRI portions of the field program in
detail. There are three other Data Volumes also:

    1. EMI (Dec. 1983): Cold Weather Plume Study, Chem I Data Volume

    2. AV (June 1983): Cold Weather Plume Study, Upper Air Measurements, Report
No. DO81-025

    3. EPA-Las Vegas (Jan. 1982): Airborne Downward Looking Lidar Measurements
During the Cold Weather Plume Study, Data Volume.  EPA-EMSL, Las Vegas, TS-
AMD-81088

    The following report prepared by SRI International provides a descriptive summary
of pertinent weather information for each day of the study, based on meteorological data
and guidance that were collected by SRI at the NWS Forecast Office in St. Peters, MO.
This report also includes selected maps and plots depicting radar summaries, satellite
photos, airmass trajectories and the upper air data of the Peoria and Salem, IL upper
air weather stations'.

    4.  SRI (June 1983):  "Meteorological Summary Report,  Cold Weather Plume
Study, St. Louis, MO." W. Viezee, SRI Project 1446 Report.

    Finally, there are the five daily data volumes related to this report of Washington
University (Appendices A3, A4, A5, A6 and A7). These data volumes present, mostly
in graphical and  partly in tabular form, the continuous data of both chemical aircraft
(EMI and MRI)  as well as the meteorological data of Rockwell, AV and NWS. These
are the only data volumes which contain plots of the MRI aircraft data. Copies of these
unpublished data volumes can be provided by either the principal author or the EPA
Project Officer.
 4.2 GDDB of CWPS on Magnetic Tapes

    Table 4.2 summarizes the daily data base of GDDB in matrix form.

    The data files are all in STATE-20 or STATE-VS formats.  Documentation for
these data formats is included in Appendix A2.3. The only data files in STATE-VS are
the AV upper air (pibal and minisonde) data files and the Rockwell T-sonde data files.

-------
                                    — 22 —

    The GDDB of CWPS is written on two 2400 foot long, 1/2-inch wide, industry-
compatible, 9-Track magnetic tapes.  The data packing density is 1600 bpi. Blocking
within each file is fixed, and block length is 1600 bytes.*  The tapes have no labels
or ANSI standard volume and file labels. Each file on a tape is separated by a single
end-of-file (EOF) mark, and two EOF marks follow the last file on the tape. The data
are encoded in  ASCII.

    Tape 1 contains a total of 35 files comprising the  data of February 12, 13, and
14. Thirty-two of these files are data files and three are daily summary files.  Tape 2
contains a total of 27 files, 13 for February  16 (1 summary file and 12 data files) and
14 for February 20 (1 summary file and 13  data files). The data files are grouped by
day, and a leader file for each day with the  name SUMMARY.mdd (mdd = 212, 213,
214, 216, and 220) simply contains a listing of the data files in that day's  data base.
Each  entry in the summary files gives the file name, organization collecting  data, type
of data, and file format.

    A listing of the daily summary files is included in Appendix 2.1. Collectively, this
listing is also a list of all the 62 files  on the two tapes. This listing of files  is followed
by a  partial  listing of the contents of each of the 12 data files of 13 February 1981
(Appendix A2.2).  For each file, the partial listing gives the full contents of the header
and the comments sections, and in-between, the contents of a few data records at the
beginning and end of the data section.

    The partial file content listings in the Appendix are followed by the documentation
of the STATE-20 and STATE-VS file formats (Appendix A2.3).
   *  All data files have fixed 1600 byte blocks. The daily summary flies (SUMARY.mdd), however,
have maximum block size of 1600 bytes.

moderate winds west northwest.

Plume;  Southeast, wind direction changing during sampling, stable, no
vertical mixing, some meandering.
        comments;  Best EHI cross comparison  In program, plume easier
to it ay with  than earlier In the day.

6) THE EMI AIRCRAFT ALSO  MADE  CONTINUOUS MEASUREMENT OF THE PARTICULATE
SULFUR AND THE  H2S04  COMPONENT OF  IT.  IT IS CURRENTLY BELIEVED THAT THE
DATA OF THESE PARAMETERS  ARE NOT USABLE. AND ARE  NOT INCLUDED HERE.
ATTEMPTS WILL CONTINUE  TO BE MADE  TO VERIFY THIS.  IF GOOD DATA IS REALIZED,
IT WILL BE MADE AVAILABLE LATER.

7) THE EMI AIRCRAFT ALSO  MADE  SOME AEROSOL SIZE DISTRIBUTION MEASUREMENTS
BASED ON AN OPTICAL PARTICLE COUNTER AND AN ELECTRICAL AEROSOL ANALYZER.
THESE DATA HAVE NOT YET BEEN PROCESSED, AND THE RAW DATA ARE NOT INCLUDED
HERE. RESULTS OF  THE  INFERRED  AEROSOL  SIZE DISTRIBUTIONS WILL BE MADE
AVAILABLE IN HARD COPY  FORM  IN THE NEAR FUTURE.

MRI AIRBORNE SAMPLING
COLD WEATHER PLUME STUDY, KINCAID GENERATING
DATA, COLLECTED FROM 02/12/81 THRU 01/20/81.

1) LOCATION DATA ARE BASED ON INTERPOLATED LONGITUDE AND LATITUDE VALUES
   BETWEEN EVENT END POINT VALUES.  END POINT VALUES ARE INFERRED FROM AIRCRAFT
   NAVIGATIONAL DATA.

2) R UNIT = CM^(2/3)/SEC

3) NT REPRESENTS AL GASEOUS NITROGEN OXIDES, INCLUDING HN03.
   NOX - NT-HN03

4> RH-CALC REPRESENTS CALCULATED RELATIVE HUMIDITY BASED ON TEMPERATURE (T)
   AND DEW-POINT (TOP) DATA ACCORDING TO FORMULA:
       RH-CALC » ( (231.8 + 1.8CTDP - 0.1TH / (231.8 + 1.62T) >**8

5) TIME IS CENTRAL STANDARD TIME (CST).

6) VALUE OF +/- 999 FOR ANY CHANNEL INDICATES NO VALID DATA.

Documentation of STATB-20 and STATE-VS File Formats

                              -69-
                        STATE-20 DOCUMENTATION


     The STATE-20 data file format has been designed for data of
a time-series form, i.e. sequential data records',  each consisting
of a time and corresponding values of a certain number of measured
variables.  Most data in the STATE data base,  (comprising the GDDBs
of MISTT, TPS, PEPE/NEROS, and CWPS) are of this form.  Hence,
STATE-20 is the most predominant data file format in these GDDBs.

File Format

     The entire file is written in fixed 80-character card images
(logical records).  Each file has the following overall structure:
                            HEADER SECTION
                              DATA SECTION
                           COMMENTS SECTION

                        EOF  (End of File mark)
     The comments section consists of an arbitrary number of
logical records with literal information of an elucidatory nature
— who, what, when, where, why, how, problems, quality assessment,
exceptions, definitions, etc.  It includes, in particular,
definitions of data variables whose names are not self-explanatory.
The comments section starts immediately following the data section.
No separation markers or records exist.  The start of the data
section and its length, however, are predefined.  The end of the
comments is followed by an end-of-file  (EOF) marker.

     The data section contains the actual data of the measured
variables, grouped into individual repeated observations.  Each
observation consists of one set of values of the measured variables
 (including date and time of the observation).  Observations are
sequential and chronological, and they all have the same format
since  the same variables are repeated in each observation.  This
observation format is a predefined syntactically correct FORTRAN
format incorporating several 80-character records in one observation,

     The header section contains important information which
self-documents the file format and contents.  It defines the
number of variables  (NVAR) and the number of 80-character
logical records  (NREC) in each observation; it identifies the
data variables by their assigned names, and gives the specific
FORTRAN format of each observation of data; and'it gives the
averaging time of the observation  (i.e. the inter-observation
time interval for continuous data) and the overall size of the
data section, i.e. the total number of observations  (NOBS) in
the data section.

H3:   Data encoding format in parentheses.  The format is assumed
     to be syntactically correct FORTRAN format with NVAR fields
     in F or E format (no I-format);  use of X for spacing and /
     for line feed may be used in the format statement.  Example
     for an observation with NVAR = 17 and NREC = 2:
     (9F8.2, 8X, /, 5F7.1, 3E13.6, 6X)

H(4a, 4b, etc...as needed):
     Names of the NVAR data variables, 8 per line, in  (8(8Al, 2X))
     format.

H(5a, 5b, etc...as needed):
     Units of the NVAR variables, 8 per line, in  (8(8A1, 2X)) format.

H6:   Number of total data observations (NOBS) in file in 110 format.

                     	 End of Header Section 	


                  Data Records (Logical Dl, D2, ... )

     The total number of logical records in this section is NREC*
(NOBS+2).  The first 2*NREC records contain the physical upper and
lower bounds of all data variables.  The remaining NREONOBS records
contain  the actual data of the NOBS observations.  The data section
thus has the following record-by-record form:

D(l to NREC):
     Physical upper bounds of data variable values in  specified
     FORTRAN format for any data observation

D(NREC+1 to 2*NREC):
     Physical lower bounds of data variable values in observation
     format

                       STATE-VS DOCUMENTATION
     The STATE-VS  format  has been designed as  a complement to
the currently existing  STATE-20  format.   STATE-20  is  appropriate
for time-series type  data,  while STATE-VS is appropriate  for
vertical soundings type data,  e.g.  pibal, radiosonde,  sodar, etc.

File Format

     Each file normally contains the  data of all vertical soundings
of a given platform  (or station) for  a  given day.   The filename has
the form nnnnnn.mdd,  nnnnnn= any I.D. of  file  (e.g. organization,
                      type of data,  etc.), and
                      mdd  =  month, day (e.g. 724=July  24)
                          =  date  of  data collection
                            (A=October,  B=November,  C=December)

The overall file format is  as  follows:
          FILE HEADER RECORDS
           SUBFILE 1
           (for  first sounding)

           @@
  subfile header records
  subfile data records
  subfile comment records
           SUBFILE 2
           (second sounding)
[  subfile header  records
<  subfile data  records
  subfile comment records
            SUBFILE n
           <§<§
           &&
           FILE COMMENT RECORDS
           EOF

-------
                              -73-
The main file header defines such specific items common to all
soundings in the file as Project, Organization Collecting Data,
Type of Data, Filename, Reported Data Parameters, their Units,
Range, etc./ Data Record Format and Size, etc.  If the data are
of vertical soundings, the first parameter should be the height
level (altitude).

The main file comments provide any additional information common
to the total data set which is judged useful, but which cannot be
included in the main file header.

Each subfile contains the information pertinent to a single sounding.
Subfiles must be arranged in chronological order.  The subfile header
specifically defines the time and location of the sounding and the
number of records (height levels for a vertical sounding) in the
subfile.  Each data record provides a height level and the corres-
ponding data of the measured parameters  (e.g. wind speed, wind
direction).  The subfile is concluded by any comment records
specific to this sounding.

Logical  record size is fixed at 80 characters.

                             (a)  Main File  Header


          The main file header defines  specific minimum  file information
     in a specific format.   In the  following header format description,
     underlined character strings are to  be fixed, as  indicated, and
     the rest of the information is variable.

Record 1: FORMAT; STATE-VS

Record 2: PHYSICAL RECORD;  80_ BYTES, LOGICAL RECORD: 80^  BYTES

Record 7: DELTA T;    VALUE =(T20/I3)     UNITS CODE =  (T39,I2)


          This record provides  information about  time  interval  between
          soundings.

          UNITS CODE =  0       indicates      interval  is irregular

                     =  1       indicates      interval  is in seconds

                     =  2       indicates      interval  is in minutes

                     =  3       indicates      interval  is in hours

           (e.g.  3-hourly soundings defined by value  =  3, code = 3).

Record  8: NO. OF  PARAMETERS PER RECORD;  (T30,I4)

Record  9: DATA  RECORD  FORMAT; (Data encoding format  in parenthesis)
                Open parenthesis to be placed in column 21.   The
                encoding format is assumed to contain a syntactically
                correct FORTRAN format specification  utilizing only
                F,  E and X format codes (no I-format  please!) and
                "read record" slashes,  suitable for decoding the
                data.   Example:  (F6.0,  2E12.4,  2F5.0,  40X)

Record  10 PARAMETER NAMES

Record  11:Logical record 11 should contain the parameter names in  the
          format:  n(8Al,  2X), n=number of parameters

Record 12:  PARAMETER UNITS

Record 13:  Logical record 13 should contain the parameter units in the
           format: n(8Al,2X), n=number of parameters.

Record 14:  DATA MINIMA

Record 15:  The actual or possible minimum values of the parameters in data
           record format

Record 16:  DATA MAXIMA

           The actual  or possible maximum values of the parameters in
           data record format

Record 17:  PLOT MINIMA

Record 18:  Suggested lower bound values of the parameters to be used for
           general plotting purposes

Record 19:  PLOT MAXIMA  .

Record' 20:  Suggested upper bound values of the parameters to be used for
           general plotting purposes.

           N.B.     Data min/max range should include range of valid data
                    values, including outlier  (but valid) values.

                    Plot min/max range would normally include normal data
                    values  (and possibly not include valid outliers).

   For stationary platforms  (e.g.  PIBAL during a  single sounding),
   initial and final positions will be same.  For a moving plat-
   form, such as an aircraft lidar making  a remote vertical profile
   sounding, the subfile may contain an average profile measured
   between aircraft initial and  final positions during averaging
   time.
