AB: The Canadian air quality model (GEM-AQ) includes an aerosol physics module which incorporates five size- resolved aerosol components and dynamic emission inventories for smoke and dust. A recent 5-year global run permitted a comparison of total optical depths, fine mode fraction (FMF) and SWIR (short wave infrared) Angstrom exponents with AERONET and MODIS retrievals over the Northern hemisphere. This communication will focus (i) on the similarities and differences obtained between measurements and model for both extensive (optical depth) and intensive (FMF and SWIR Angstrom exponent) parameters and (ii) how these comparisons can yield insight into source emission characteristics.
