Section 1: Introduction
CALMM5 is a processor that extracts and interprets data in the output file from MM5 (Version
3), and creates a file of meteorological data for direct input to CALMET in either the preferred
3D.DAT format or the MM4.DAT format.
CALETA is a processor that extracts and interprets data in selected output files from NAM(Eta),
and creates a file of meteorological data for direct input to CALMET in its 3D.DAT format.
CALWRF is a processor that extracts and interprets data in selected output files from WRF (the
Weather Research and Forecasting Model), and creates a file of meteorological data for direct
input to CALMET in its 3D.DAT format.
CALRUC is a processor that extracts and interprets data in selected output files from RUC, and
creates a file of meteorological data for direct input to CALMET in its 3D.DAT format.
CALRAMS is a processor that extracts and interprets data in selected output files from RAMS,
and creates a file of meteorological data for direct input to CALMET in its 3D.DAT format.
CALTAPM is a processor that extracts and interprets data in selected output files from the
CSIRO’s TAPM Model (The Commonwealth Scientific and Industrial Research Organisation;
The Air Pollution Model), and creates a file of meteorological data for direct input to CALMET
in its 3D.DAT format.
Preprocessors and utilities provided with the modeling system for use with CALPUFF include:
OPTHILL is a processor program which uses topographical data (such as terrain maps) to
develop hill shape factors that are used in the subgrid scale complex terrain (CTSG) module in
CALPUFF.
FEPS2BAEM is a conversion utility which creates a time-varying emissions file for buoyant
forest fire area sources based on the output from the U.S.D.A Forest Service Fire Emissions
Production Simulator Model (FEPS).
The meteorological modeling with the CALMET model is detailed in Figure 1-2. Note that the
preprocessors for the raw meteorological data are written to accommodate the U.S. National Climatic
Data Center (NCDC) file formats. Figure 1-3 is the schematic of the CALPUFF dispersion model
indicating the model input and output files. The postprocessing approach for the meteorological and
dispersion modeling results is shown in Figure 1-4 and Figure 1-5.
A series of reports and user's guides describe the components of the modeling system. The technical
formulation for CALPUFF (Version 5) and CALPOST (Version 5) is contained in Scire et al. (2000a),
and that for CALMET (Version 5) and the meteorological and geophysical preprocessing programs are
