Section 1: Introduction CALMET reads the user's inputs from a "control file" with a default name of CALMET.INP. This file contains the user's selections of the various model options, input variables, output options, etc. CALPUFF Data Requirements The input data sets used by CALPUFF are summarized in Table 1-4 (also see the modeling system flow diagram, Figure 1-1). CALPUFF reads user inputs from a "control file" with a default name of CALPUFF.INP. This file contains the user's selections for the various model options, technical input variables, output options, and other user-controllable options. A meteorological data file (CALMET.DAT) contains hourly or sub-hourly gridded fields of micrometeorological parameters and three-dimensional wind and temperature fields. The meteorological data file also contains geophysical data such as terrain heights and land use which are required by both the meteorological model (e.g., for terrain adjustment of the wind fields) and by the CALPUFF model. The contents of the CALMET.DAT input file and the other input data bases are summarized in Table 1-5. Options also exist for using single-station meteorological data in ISCST3, CTDMPLUS, AERMOD, or AUSPLUME data format. Five files are provided for the input of emissions data. The control file, CALPUFF.INP includes point, line, volume and area source data for sources with constant emission parameters or those that can be described by a cycle based on time of day (24 factors), month (12 factors), hour and season (24 x 4 factors), wind speed and stability class (6 x 6 factors), or temperature (12 factors). Separate scaling factors can be specified for each source-species combination. Arbitrarily-varying source data may be provided in files for point sources (default name PTEMARB.DAT), area sources (default name BAEMARB.DAT), line sources (default name LNEMARB.DAT), and volume sources (default name VOLEMARB.DAT). Hourly or sub-hourly observations of ozone data are used in the calculation of SO 2 and NO x transformation rates if the MESOPUFF II chemical transformation scheme is selected. Ozone data for one or more ozone stations are read from a data file called OZONE.DAT. 1-31
