CALPUFF and Postprocessors

WFLX.DAT File - Data Records
The WFLX.DAT data records consist of a set of "NWFOUT+1" records for each hour of the CALPUFF
runs (NWFOUT is the number of species flagged as being stored in the output file). The first record of
each set contains the date and hour of the data in the records which follow it. The next "NWFOUT"
records contain predicted one-hour averaged wet deposition fluxes in g/m 2 /s for each relevant species (see
Table F-57).
Sample FORTRAN read statements for the data records (in uncompressed format) are:
READ(iunit)nyrb,njulb,nhrb,nsecb,nyre,njule,nhre,nsece
READ(iunit) istype,isnum,sname,sxkm,sykm

CALPUFF contains an option to compress the data by replacing strings of zeroes with a coded repetition
factor. The factor is a negative number whose absolute value indicates the number of consecutive zeroes
that have been replaced by the repetition factor. This method is especially useful in reducing the size of
the output file when large segments of the receptor arrays lie upwind of the puffs during an hour, thereby
producing long strings of zeroes in the output arrays. For example, the following record with data for 20
receptors requires 20 unpacked words:
0.0, 0.0, 0.0, 0.0, 0.0, 1.2, 3.5, 0.0, 0.0, 0.0,
0.0, 0.0, 0.0, 0.7, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0
These data in packed form would be represented in six words:
-5., 1.2, 3.5, -6., 0.7, -6.
