Scientists Examine the Black Carbon Impacts of Wildfires and Biomass Burning

Colorado State University researchers recently published two PNAS papers that address the deposition of aerosols and the effects of black carbon on ice nucleation.

Graham Feingold: Modeler of Aerosol-Cloud Interactions

A veteran researcher revs up an ASR project studying the influence of aerosols on the cloud radiative effect.

Two New Funding Opportunities for 2021

DOE Announces Funding for ASR Science and Early Career Research Program

Investigator of Arctic Clouds and their Elusive Microphysics

During a three-year ASR project, Adele Igel is doing foundational work that will improve models of cloud cover in polar regions.

ASR-Funded Modeler of the Land-Atmosphere Interface

Jerome Fast studies the coupling of the Earth’s surface with the lowest layer of the atmosphere, where storms and precipitation are made

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.
