Codes & Related Processors: EPA-Approved Version
The CALPUFF modeling system is comprised of CALMET, CALPUFF,
geophysical data preprocessors, meteorological data preprocessors,
and several postprocessors designed to operate on CALMET and CALPUFF
output files. The complete CALPro system, including graphical user interfaces
and executables for CALMET, CALPUFF, CALPOST, as well as several additional
utility programs, may be installed by downloading and installing "CALPro_Setup_EPA_2007Jun29.exe",
available here.
The downloads available here focus individually on each component, providing a brief overview of
the purpose, sample input and output files, the executable, and the
FORTRAN code (in most cases). The sample input and output files are
interrelated among the processors, producing a demonstration of the
full system. This demonstration involves a single application to a
hypothetical source, using real meteorological and geophysical data.
The files for this demonstration are packaged by individual processor. There is
typically a single ZIP file for each, but in the
cases where large input data files (e.g., land use or terrain) are part
of the demonstration, separate ZIP files for the data are provided. To limit the amount of data transferred, please
download the large data files only if they have been updated since your last
download.
Create a directory 'C:\CALPUFF\Demo' (or one of your choosing)
on your system as the root for the demonstration directories.
Then download the ZIP files to that directory. These ZIP files
contain the directory structure for the demonstration. If you are
using a Windows-based utility to unzip these files, double-click on
each in turn to begin a standard installation. If you are using a DOS
version of PKUNZIP, be sure to use the "-d" switch to unpack the
directory structure. For example, to expand CTGPROC.ZIP type:
pkunzip -d ctgproc [return]
These files should be
expanded once the system has been installed (i.e. after the
GUI, utilities, and initial test cases are loaded to disk).
To expand all of the demonstration files, make sure that
at least 200 MB of disk space is available. If you
have do not have enough space, you may expand and process the files for each
processor in turn. There are several large input data files
(e.g. the USGS CTG files) that may be deleted once the processing
is completed.
The demonstration is best approached in the following sequence: Geophysical
Preprocessors, Meteorological Preprocessors, Main Models (CALMET,
CALPUFF), and Postprocessors. Process the terrain data first, and
then land use, etc. All of the processing should be done in the individual
subdirectories. Go to each in turn, and read the README.TXT
file. This file contains the documentation for each processor.
Note that all of the processing relates to the same
application except the examples for BUOY.
Once you have gone through the demonstration, you may
delete the data files used in the demonstration, but keep
the executables, documentation, and the control files for regular use.
