Short summary

Airborne measurements in Baltimore-Washington, DC allow for an understanding of the relationship between aerosol extinction which can be measured by satellites and aerosol mass used for air quality monitoring. Extinction was found to be driven to first order by aerosol loadings; however, humidity-driven aerosol hydration plays an important secondary role. Spatial and diurnal variability in aerosol composition were small, but day-to-day variability in aerosol hygroscopicity must be accounted for.
