In these simulation we removed all small fires (of less than 100 acres woodland and less than 300 acres grassland) to determine whether small fires have significant visibility impacts. The small fire removed case is compared CMAQ 36km BaseA 2002 (Base case minus sensitivity case) to show the effect of small fires.

2002 Annual CMAQ modeling using interim emission inventory version C.
Inital testing of CMAQ has been completed using the 2002 Interim Emissions Inventory for Winter (Jan-Feb-Dec) and Summer (Jun-July-Aug) 2002. CMAQ Model Performance evaluation plots and performance metrics are included for all monitoring sites in the WRAP states and all sites in the continental US, for the base case.
Results for a summer & winter sensitivity case with clean boundary condition are summarized here:
Detailed plots are are available here:
CMAQ model simulations were performed using the Tagged Species Source Attribution (TSSA) algorithm to assess source contributions to PM at receptor sites. These results are summarized below as average source contributions on the 20% best and 20% worst days. Best and worst days were determined either using the model predictions and also using ambient data for the IMPROVE sites. Barplots for several groups of receptors sites are listed below:
