Abstract

Aerosol radiative forcing is the difference between the radiative effect of aerosols now and during pre-industrial times. Calculating that difference requires understanding the sources of the particles. I will present how data sets as diverse as single particle analysis, the IMPROVE ground-based network, and satellite data can be used to constrain the sources and radiative forcing of aerosols. I will consider the sources of lead and soil dust in the United States and move to some satellite-derived estimates of global aerosol sources and how they are changing.
