CALPUFF Control File Inputs - Input Group 0
Input and Output File Names
Input Group 0 consists of several parts. The first part contains the control variables NMETDAT,
NMETDOM, NPTDAT, NARDAT, NVOLDAT, and all of the filenames listed above. The remaining
parts, Input Groups 0a through 0d, are only needed when more than one CALMET or variable emissions
files are used in the simulation. If a number of separate CALMET simulations are made to span the full
modeling period, this feature allows a single application of CALPUFF to use all of the CALMET
simulations in sequence. This feature is signaled by an NMETDAT value greater than one. Further
provision is made to provide multiple CALMET domains through NMETDOM > 1. Similarly, having the
ability to use multiple emissions files allows you to place source groups with markedly different timevariations
into separate files.
If you have no CALMET file (i.e., you are using one of the other options for providing meteorological
data to CALPUFF such as ISC meteorological data), set NMETDAT=0:
INPUT GROUP: 0 -- Input and Output File Names

CALMET.DAT input * METDAT = *

ISCMET.DAT input ! ISCDAT = ISCMET.DAT !

Number of CALMET.DAT files for run (NMETDAT)
Default: 1 ! NMETDAT = 0 !
If you have a single CALMET file, set NMETDAT=1:

If you have 3 CALMET files, set NMETDAT=3:
