GISS research into Atmospheric Composition and Climate explores how changes in reactive gases and aerosols both affect climate via radiation and cloud feedbacks and are affected by climate through various feedback processes. Interactions are explored across a range of climate simulations including paleo-climate, interannual variability and future projections. Policy impacts are focused on the characterization of a broad range of impacts of anthropogenic activities, with a particular emphasis on emissions pathways designed to reduce multiple environmental damages. We evaluate the effects of the full suite of climate-altering pollutants emitted by particular activities and how these might change under different policies, and assess the simultaneous responses of regional temperatures, precipitation and air quality. Fundamental research into mechanistic paramterizations of aerosol and gas phase processes, microphysics and chemistry is undertaken as well as studying chemical interaction between the atmosphere and the surface including emission generating activities, such as fires, wetlands and biological activity. In general we are interested in all mechanisms that affect climate via atmospheric composition pathways.
