Robinson, Carnegie Mellon University Talk Title: Updating our conceptual model for fine particle emissions from combustion systems Abstract: Atmospheric particles play an important role in the Earth’s engergy balance; they are also strongly\n associated with adverse human health effects. Motor vehicles, wood stoves, and other\n combustion systems are major sources of atmospheric particles. However, quantifying the\n impact of these sources on air quality and global climate remains a major uncertainty. \n \n This talk will describe recent field, laboratory, and modeling results on organic particle\n emissions from combustion systems. The results reveal a dynamic picture in which low\n volatility organics evaporate, oxidize, and recondense as they are transported away from the\n source. This new picture alters our understanding of the contribution of combustion sources to\n urban and regional pollution and brings chemical transport model predictions into better\n agreement with field observations. The talk will conclude with a brief discussion of future\n research needs and the implications of this new conceptual model for our understanding of\n source contributions to human exposures and the design of regulations to control organic\n aerosols. Biography: Allen Robinson: Dr. Allen Robinson is a Professor in the Departments of Mechanical\n Engineering and Engineering and Public Policy and the director of the Center for Atmospheric\n Particle Studies at Carnegie Mellon University. His research examines the impact of emissions\n from combustion systems on urban and regional air quality and global climate, with a focus on\n fine particulate matter. He was a visiting faculty fellow at the Cooperative Institute for\n Research in Environmental Studies at the University of Colorado and NOAA in Boulder, \n Colorado and a postdoctoral fellow at the Combustion Research Facility at Sandia National\n Laboratories in Livermore, California. He received his Ph.D. from the University of California at\n Berkeley in Mechanical Engineering in 1996 and a B.S. in Civil Engineering from Stanford\n University in 1990. He received the Carnegie Institute of Technology Outstanding Research\n Award in 2010, the Ahrens Career Development Chair in Mechanical Engineering in 2005 and\n the George Tallman Ladd Outstanding Young Faculty Award in 200. He is the author of more\n than 80 peer-reviewed publications on air pollution, atmospheric chemistry, and biomass\n energy.
