COMBLE to Study Outbreaks of Consequential Cold Air

A better quantitative grasp of cold-air outbreaks will improve the way they are represented in earth system models.

Cracking the Puzzle of Ice in Clouds

Hugh Morrison leads an Atmospheric System Research project on parameter variability in modeling ice microphysical processes.

Deciphering Cold-Air Outbreaks

A new ARM- and ASR-led campaign will investigate extrusions of cold air over warm waters.

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.
