Yunyan Zhang: Modeler of Boundary-Layer Clouds

A California researcher leverages ASR funding and ARM data to boost understanding of land-atmosphere-cloud interactions.

Atmospheric Aerosols and Their Chemical Complexities

With ARM and ASR support, a cross-country pair of collaborators use imaging strategies to peel open some enduring aerosol mysteries.

Probing Wet Fire Smoke in Clouds: Can Water Intensify the Earth's Warming?

Now Open: 2022 INCITE Call for Proposals

INCITE seeks proposals for high-impact, computationally intensive research campaigns.

Arctic Lightning Strikes Will More than Double as Climate Warms

More lightning strikes will result in more wildfires—a trend already observed over the past half decade.

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.
