Ahead in the Clouds

ASR scientist builds custom chamber helping uncover how aerosol particles and clouds contribute to Earth’s changing climate.

An ASR Investigator of Deep Convection

At UCLA, Fiaz Ahmed leads a team developing an ambitious new tool for understanding storm clouds.

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.
