Model requires many tracers to track reactive species, especially NOy and NO3. Results in large data sets and slow run times. Multiple simulations needed to apply tracers to all species of interest. Although expensive, this is much less costly than running large numbers of sensitivity simulations. WRAP Regional Modeling Center, Attribution of Haze Meeting, Denver CO 7/22/04 Summary of Results There are differences in the source areas and categories that contribute on to PM on the best versus the worst days. Challenge in evaluating many days & many sites. Boundary conditions (from GEOS-CHEM) is consistently a large contributor. Additional investigation of mass conservation error is needed.
