<strong>Table</strong> 9-3 (Continued)<br />

CALPUFF Control File Inputs - Input <strong>Group</strong> 8<br />

Dry Deposition Parameters - Particles<br />

Input <strong>Group</strong> 8 consists <strong>of</strong> a table containing the geometric mass mean diameter (microns) and the<br />

geometric standard devi<strong>at</strong>ion (microns) required by the resistance deposition model for computing<br />

deposition velocities for particul<strong>at</strong>e m<strong>at</strong>ter.<br />

<strong>The</strong>se parameters must be specified for each pollutant with a dry deposition flag <strong>of</strong> "2" in the species list<br />

(Input <strong>Group</strong> 3) indic<strong>at</strong>ing the use <strong>of</strong> the resistance model for a pollutant deposited as particul<strong>at</strong>e m<strong>at</strong>ter.<br />

<strong>The</strong> form<strong>at</strong> <strong>of</strong> the input table is shown below:<br />
