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

Arctic warming by abundant fine sea salt aerosols from blowing snow

We found that the sublimation of blowing snow produces high concentrations of fine-mode sea salt [...] Read more

Unraveling the continuous ice formation in arctic mixed-phase clouds with a novel column model

Arctic mixed-phase clouds, wherein supercooled droplets and ice crystals coexist, play a crucial [...] Read more

Entrainment is locally inhomogeneous, but can appear globally homogeneous

We show, through laboratory experiments, that when dry air mixes with cloudy air, some cloud [...] Read more
