Abstract: Online real-time aerosol mass spectrometry has been used by atmospheric scientists to better understand aerosol particles in the atmosphere. The Aerodyne Aerosol Mass Spectrometer utilizes thermal vaporization and electron ionization (70eV) to measure the size resolved composition of atmospheric aerosol particles. Using this instrument we can measure the composition, size, and shape of atmospheric particles play to better understand the impact they have on air quality and climate. Chemical changes in aerosol particle populations result from atmospheric processing and/or differences in the sources of these particles (e.g. vehicle emissions vs cooking emissions). Field measurements over a period of weeks to months with continual 1-5 minute data resolution provide large datasets that can be processed and analyzed to understand the aerosol composition and sources for a particular location. Results from recent field projects in Philadelphia, Antarctica, and Nepal will be discussed.
Bio: Dr. Peter DeCarlo is an Assistant Professor with a joint appointment in the Department of Civil, Architectural, and Environmental Engineering, and the Department of Chemistry at Drexel University. Dr. DeCarlo has a Ph.D. in Atmospheric Science from the University of Colorado, and a BS in Biochemistry from the University of Notre Dame. He uses state-of-the-art instrumentation to measure the chemical composition of particulates and gases in the atmosphere to better understand air quality and climate impacts of human emissions. He has made air quality and climate related measurements from planes, trucks, and stationary sites all over the world to better understand emissions, sources, and subsequent chemical reactions of pollutants in the atmosphere. Dr. DeCarlo also is interested in the intersection of science and policy, and was an AAAS Science Policy Fellow at the US EPA prior to starting his faculty position at Drexel. Funding for his research comes from the National Science Foundation, Electric Power Research Institute, and the Department of Transportation. Dr. DeCarlo has co-authored over 80 peer reviewed publications and recently was identified as a highly cited researcher by Thompson Reuters (2014, 2015, and 2016).
