Three-year study to improve understanding of cloud-aerosol interactions

February 13, 2018

Clouds in all their forms are familiar, but scientists still grapple with understanding the processes that influence their shapes, sizes, and life cycles.

These vastly consequential bodies of ice and water hold and dispense rain and snow, cast shadows from the sun, and blanket the Earth. Aerosols, the particles that help clouds form, are swept up from the surface and elsewhere.

But how do clouds and aerosols interact? What are the small-scale processes that drive those interactions, and how can they be predictively modeled?

To address these questions, EVS computer modelers Rao Kotamarthi and Yan Feng and EVS observationalist Virendra Ghate have teamed up with joint principal collaborators from Brookhaven National Laboratory under a three-year science focus area (SFA) project renewed in fall 2017 by the Atmospheric System Research (ASR) program at DOE.
