The U.S. Department of Energy’s Atmospheric System Research program advances process-level understanding of the key interactions among aerosols, clouds, precipitation, radiation, dynamics, and thermodynamics, with the ultimate goal of reducing the uncertainty in global and regional climate simulations and projections.

Research Highlights
