POSTUTIL  Postprocessor
----------------------------------------------------------------------

Purpose:
--------
          Operates on one or more output data files from CALPUFF
          to sum, scale, repartition (nitrates), and/or compute
          species derived from those that are modeled, and outputs
          selected species to a single file for CALPOST processing.

Demonstration:
--------------

          Compute total sulfur, nitrogen and PM10 hourly deposition
          fluxes from modeled wet and dry deposition fluxes of SO2,
          SO4, NO, NO2, HNO3, NO3, and PM10.

Procedure:
----------

1.  This application is run from the DOS prompt.

2.  Instructions

    (a)  Run the program by typing:

         POSTUTIL [return]

    (b)  The program reads the processing instructions from
         POSTUTIL.INP, and overwrites the output files listed above.

    (c)  Review the .LST file for the configuration used, and other
         information from the input files read during execution.
