3.9 CONTROLLING INPUT AND OUTPUT FILES

     This section describes the various input and output files used by the ISC models, and discusses control of input and output (I/O) on the IBM‑compatible PC environment.  Much of this discussion also applies to operating the models in other environments.

3.9.1 Description of ISC Input Files

     The two basic types of input files needed to run all of the ISC models are the input runstream file containing the modeling options, source data and receptor data, and the input meteorological data file.  Each of these is discussed below, as well as a special file that may be used to initialize the ISCST model with intermediate results from a previous run.

3.9.1.1 Input Runstream File.

     The input runstream file contains the user‑specified options for running the various ISC models, includes the source parameter data and source group information, defines the receptor locations, specifies the location and parameters regarding the meteorological data, and specifies the output options.  The basic structure of the input runstream file is  the same for all three models, although the list of available keywords for defining options, and the exact syntax for certain keywords are slightly different between the Short Term and Long Term models.  Details regarding the keywords and parameters used in the input runstream file are provided in Section 3, and Appendix B.

     For the PC‑executable versions of the models available on the SCRAM BBS, the runstream file is explicitly opened by the models using a Fortran OPEN statement, and the integer variable, INUNIT, specifies the unit number for the file.  The variable INUNIT is initialized to a value of 5 in a BLOCK DATA subprogram of the model, which corresponds to the default input unit for Fortran.  The INUNIT variable is included in a named COMMON block (FUNITS) in the MAIN1.INC include file, and is therefore available to all of the necessary subroutines.

     Since the input runstream file is opened explicitly by the PC‑executable versions of the models, the model will take the first parameter on the command line when running the model as the input filename.  No DOS redirection symbol should be used preceding the runstream filename.
