COVID-19 Update for April 3: Read this important message from Gary Geernaert, Director of the Climate and Environmental Sciences Division within the U.S. Department of Energy's Office of Biological and Environmental Research. 

A Whirlwind Researcher of Cloud Updrafts

Neil Lareau journeys from oil painting to studying cold-air pools, wildfires, and how pulses of surface air help make clouds.

Stephen Springston: Master of Aerosols

“We’re trying to get a fundamental, process-level understanding of what goes into the atmosphere.”

The Puzzle of Low Clouds

One researcher’s early fascination for computers and severe weather led to confronting the uncertainties of modeling shallow clouds.

ARM Instruments, ASR Collaboration

Adam Theisen leads ARM into a new era of data gathering and checks in with ASR along the way.

DOE’s SCGSR Program Creates Opportunities for Graduate Students

DOE's SCGSR program is accepting applications for the 2020 Solicitation 1. The deadline is 5:00 pm Eastern Time on Wednesday, May 6, 2020.

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.
