Short summary

We use a forward geophysical approach to derive surface PM_2.5 distribution from satellite AOD over the northeastern US by applying relationships between surface PM_2.5 and column AOD from a regional air quality model (CMAQ). We use multi-platform surface, aircraft, and radiosonde measurements to quantify different sources of uncertainties. We highlight model representation of aerosol vertical distribution and speciation as major sources of uncertainties for satellite-derived PM_2.5.
