The Aerosol and Microphysics Group makes major advances in the understanding of atmospheric aerosol processes and effects including: formation mechanism, transport, removal, roles in biogeochemical cycles, atmospheric exchange processes, and effects on climate via radiative, cloud, and heterogeneous chemical processes.
