3. The main programs for processing and analysis are:
PREPRO.EXE -- a preprocessing program
TOMKEHR.EXE -- the Umkehr analysis program
RUNPRE.BAT -- a batch file used to launch PREPRO.EXE
RUNUMK.BAT -- a batch file used to launch TOMKEHR.EXE
The proper execution of PREPRO.EXE and TOMKEHR.EXE requires that the
following files also be present:
UJJJYY.nnn -- Brewer Umkehr data file to be analyzed
OZOAVGYY.nnn -- daily average ozone value file
SXUNI4M.DAT
STDTABS.DAT
O3TABLE.DAT
CQMS.DAT
PRESETUP.nnn -- a file containing station data which is created by using a text
editor to modify a sample file such that it contains:
-- the ozoavg file to be used
-- the station number, station code, latitude, longitude
UMKSETUP.nnn -- a file created during the Brewer calibration containing
pointers to the above .DAT files, ozone coefficients, and sun
angle information.
-- must be edited to include as line 7 the following:
3,6,11,12,1,1.0,pressure, where pressure is mean station pressure
in millibars
4.
The batch file RUNPRE.BAT will invoke PREPRO.EXE and set the necessary
parameters when the command line RUNPRE JJJYY.nnn is issued.
5.
Three files are created following the successful execution of PREPRO:
UPJJJYY.nnn -the preprocessor output listing
UDJJJYY.nnn -output data to be used by the analysis program
UGJJJYY.nnn -reduced data
6. The batch file RUNUMK.BAT sets up and runs TOMKEHR.EXE when the command line
RUNUMK JJYY.nnn is issued.
7. Successful execution of TOMKER results in the creation of three files:
USJJJYY.nnn
UOJJJYY.nnn
UNJJJYY.nnn suitable for graphing the ozone profile.
Some useful information on the Umkehr processing software and its use may be found in the
following three documents written by Dr. T.C. McElroy:
-- Umkehr Inversion Algorithm for the Brewer Ozone Spectrophotometer
-- Readme.Doc
-- Readme.V3
