Scientists are grappling with a high-quality, comprehensive dataset on cold-air outbreaks in northern Norway.

How Turbulence and Aerosols, in Concert, Help Form Clouds

A new PNAS paper out of Michigan Technological University will sharpen how the effect of turbulence is represented in predictive cloud microphysics models.

New SCGSR Fellow’s ASR Work Examines Clouds Over Thinning Sea Ice

A winding road led Sarah Murphy from Maine to Vermont, the Great Plains, Greenland, Washington State University, and to Pacific Northwest National Laboratory.

Time to Say Goodbye to the MOSAiC Floe

The MOSAiC floe’s days are numbered, but Polarstern will continue the expedition farther north.

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.
