Short summary
This study is the most comprehensive evaluation of CMAQ inorganic aerosol size-composition distributions conducted to date. We compare two methods of inferring PM2.5 concentrations from the model: (1) based on the sum of the masses in the fine aerosol modes, as is most commonly done in CMAQ model evaluation; and (2) computed using the simulated size distributions. Differences are generally less than 1 microgram/m3, and are largest over the eastern USA during the summer.
