10.2 CALSUM
The CALSUM program is designed to combine a set of CALPUFF output data files for individual sources
or source groups into a single file with the same format. The concentrations or deposition fluxes in each
file may be scaled using a linear operator of the form (a*X+b), where 'X' represents either the
concentration or the flux, "a" is the multiplicative constant, and "b" is the additive constant (g/m 3 or
g/m 2 /s). The files combined must be of the same type, containing either concentrations, wet deposition
fluxes, or dry deposition fluxes. The periods contained in the files must be identical.
Table 10-5 lists the input and output files for one application of CALSUM. Both the control file name
(CALSUM.INP) and the list file name (CALSUM.LST) are set in the program, so the user cannot change
these. All CALPUFF output file names must be provided by the user, and these are placed in the control
file. The control file structure is listed in Table 10-6, and a sample control file is listed in Table 10-7.
To run this program, place the executable and the control file (edited to reflect your application) in the
same directory or folder, and enter the following command-line:
CALSUM
The program will open the control file for your application, and follow the instructions. Messages appear
on the screen as the program runs, and full documentation for the run is written to the list file. A sample
list file is presented in Table 10-8.
