4.4.3. Select which pollutants in the inventory are kept

Users have the option of deciding at run time which inventory pollutants will be kept from an inventory provided in ORL format. The INVTABLE file lists all possible criteria and toxic pollutants. While the example files are fairly comprehensive, it is possible users may need to add pollutants to this file using the INVTABLE file format description. Additionally, users can change which pollutants are kept for further processing in SMOKE. This is done by setting the Keep column of the file to Y for all pollutants that SMOKE should keep, all pollutants in these files must have the Keep column set to Y.

Both the run time and intermediate file sizes can be reduced by keeping only the pollutants that you need to include for modeling purposes. In the bulleted list below, we provide several examples of why a user might want to change which pollutants are kept.
