Variable General Info
Pollutant concentration (emission source) ?Comment:The initial emmission rate is used to generate a pollutant emmission source that includes the effects of the vegetation. This subsequent emmission source is used for the remaining regions. Since deposition occurs only within the vegetation, the emission source strength is modified only in Region I. |
