Aerosol, Cloud, and Precipitation research are among the nine cross-cutting themes of the Earth Sciences Division at NASA's Goddard Space Flight Center. The AeroCenter-Cloud Precipitation Center (AeroCenter-CPC) is an interdisciplinary union of researchers at NASA Goddard and other organizations in the Washington DC metropolitan area (including NOAA, University of Maryland, and other institutions) who are interested in many facets of atmospheric aerosols, clouds, and precipitation. AeroCenter interests include aerosol effects on radiative transfer, clouds and precipitation, climate, the biosphere, the role of aerosols in air quality and human health, and the atmospheric correction of aerosol blurring of satellite imagery of the ground.  CPC topics include 1) cloud-precipitation processes and interactions with surface processes, aerosols, mesoscale dynamics, and large scale circulations, 2) remote sensing, radiative transfer, and scattering theory of cloud and precipitation particles, 3) cloud microphysics and convection measurements and parameterizations, and 4) satellite missions and field campaigns associated with cloud and precipitation processes.
