His research is focused on the measurement of particles and gases in the atmosphere, typically focused on the use of aerosol mass spectrometers. He has made measurements in cities, remote mountaintops, airplanes, and mobile trucks to study issues of air quality, atmospheric chemistry, climate impacts, and identification of pollution sources. This is his first trip to Antarctica, and he is looking forward to using aerosol mass spectrometry to study the aerosol particle composition in such a pristine environment. Dr. DeCarlo is co-Principle Investigator of the 2ODIAC project. (He is also a new father)
