Climatic effects of atmospheric particulate matter (aerosols), global and regional models of atmospheric chemistry, and air quality in developing countries.
Carnegie Mellon 2001-
Aerosol Effects on Climate
Anthropogenic aerosols cool the earth's climate by reflecting sunlight back to space and by serving as nuclei for cloud droplet formation. Their net effect has been to partially offset global warming from greenhouse gases, but uncertainty in the magnitude of this effect has complicated the assessment and forecasting of climate change. Research in this area focuses on improving the representation of aerosols in global climate, chemistry, and transport models by incorporating size-resolved aerosol microphysics and thermodynamics and testing these improved aerosol models against observations from ground networks, intensive field campaigns, and satellites. Other work examines how aerosols influence cloud reflectivity in small-scale, detailed simulations of cloud formation.
Regional Air Quality Modeling
Regional air quality models are being developed that predict the concentrations of ozone and particulate matter resulting from a given set of emissions. Specific goals in this area of research are to improve the computational efficiency of air quality models such that multi-year time periods can be simulated, better constrain the emissions of ammonia through inverse modeling, and examine the costs and benefits of air pollution control policies in developing countries.
