Note that the title parameter field does not need to be in quotations, even though it represents a single parameter.  The model simply reads whatever appears in columns 13 through 80 of the TITLEONE card as the title field, without changing the lower case to upper case letters.  Leading blanks are therefore significant if the user wishes to center the title within the field.  Note also that the spacing and order of the secondary  keywords on the MODELOPT card are not significant.  A MODELOPT card that looked like this:

CO MODELOPT   RURAL   CONC                 DFAULT

4

would have an identical result as the example above.  It is suggested that the user adopt a style that is consistent and easy to read.  A complete description of the available modeling options that can be specified on the MODELOPT keyword is provided in Section 3.

     Since the pollutant in this example is SO2, we will probably need to calculate average values for 3‑hour and 24‑hour time periods, and we also need to calculate averages for the full annual time period.  Our runstream file might therefore look something like this after adding two more keywords:

CO STARTING

CO TITLEONE A Simple Example Problem for the ISCST Model

CO MODELOPT  DFAULT  RURAL  CONC

CO AVERTIME  3  24  PERIOD

CO POLLUTID  SO2

5

Note again that the order of the parameters on the AVERTIME keyword is not critical, although the order of the short term averages given on the AVERTIME keyword will also be the order in which the results are presented in the output file.  The order of the keywords within each pathway is also not critical in most cases, although the intent of the input runstream file may be easier to decipher if a consistent and logical order is followed.  It is suggested that users follow the order in which the keywords are presented in Section 3, in Appendix B, and in the Quick Reference, unless there is a clear advantage to doing otherwise.
