Jason Tomlinson's primary area of research is the interaction between aerosols and clouds and the resulting effect on the climate. He is a payload scientist for the U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF). That program obtains airborne measurements to answer key science questions in support of aerosol, cloud, and climate research.
