This appendix provides an overview of the Community Multiscale Air Quality (CMAQ) model and the modeling system used for simulating pollutant concentrations and deposition for the years 2002 through 2005. Included in this appendix are the results of a model performance evaluation in which model predictions of sulfur dioxide (SO2), nitrogen dioxide (NO2), SO4 2-, total NO3 -*, and ammonium (NH4 +) concentrations and SO4 2-, NO3 -, and NH4 + wet deposition are compared to observations.
