 2.0 GETTING STARTED ‑ A BRIEF TUTORIAL

     This section provides a brief tutorial for setting up a simple application problem with the ISC Short Term model, which serves as an introduction for novice users to the ISC models.  The example illustrates the usage of the most commonly used options in the ISC models for regulatory applications.  A more complete description of the available options for setting up the ISC models is provided in Section 3.

     The example problem presented in this section is a simple application of the ISCST model to a single point source.  The source is a hypothetical stack at a small isolated facility in a rural setting.  Since the stack is below the Good Engineering Practice (GEP) stack height, the emissions from the source are subject to the influence of aerodynamic downwash due to the presence of nearby buildings.  The tutorial leads the user through selection and specification of modeling options, specification of source parameters, definition of receptor locations, specification of the input meteorological data, and selection of output options.  Since this discussion is aimed at novice users of the ISC models, a general description of the input file keyword/parameter approach is provided first.

2.1 DESCRIPTION OF KEYWORD/PARAMETER APPROACH

     The input file for the ISC models makes use of a keyword/parameter approach to specifying the options and input data for running the models.  The descriptive keywords and parameters that make up this input runstream file may be thought of as a command language through which the user communicates with the model what he/she wishes to accomplish for a particular model run.  The keywords specify the type of option or input data being entered on each line of the input file, and the parameters following the keyword define the specific options selected or the actual input data.  Some of the parameters are also input as descriptive secondary keywords.
