Deciphering Cold-Air Outbreaks

A New ARM- and ASR-Led Campaign Will Investigate Extrusions of Cold Air Over Warm Waters.

Perspectives on the MOSAiC Expedition from an ASR Scientist

Jessie Creamean, a research scientist at Colorado State University, shares why she is going on the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) field campaign.

Delphine Farmer: Investigator of Atmospheric Organic Compounds

Atmospheric chemist Delphine Farmer will measure carbon particle deposition rates in regions of the world where near-permanent snow and ice is altered by soot.

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.
