APPEND  Postprocessor
----------------------------------------------------------------------

Purpose:
--------
          Operates on two or more output data files from different
          CALPUFF runs to scale and sum the results into a single
          file for CALPOST processing.  The data files combined may
          be either concentration or flux files, and they must cover
          the same time period.

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

          Scale concentrations from two identical concentration data
          files by 0.5 and sum the results.

 CALSUM.EXE   Executable    514,860     CALSUM executable


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

1.  This application is run from the DOS prompt.

2.  Instructions

    (a)  Run the program by typing:

         CALSUM [return]

    (b)  The program reads the processing instructions from
         CALSUM.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.
