Document Title: Atmospheric Aerosols
Category: Atmospheric Sciences
Media Type: Graphics
Date of Image/Photo: October 2013
Background: Tiny but mighty. Aerosols are bits of dust, soot, and chemicals in the air that are intensely scrutinized by scientists because they affect climate and weather in so many big ways. These multi-talented specks can absorb or scatter the sun's energy and change what happens inside clouds. Considering the many complex and sometimes conflicting climate effects, PNNL scientists have developed a new representation to account for aerosols efficiently and accurately within one of the leading global climate models. This scientific advance will help provide a clearer picture of the future climate. http://www.pnnl.gov/science/highlights/highlight.asp?id=1174&groupid=749
