Aerosol & Cloud Chemistry

The Center for Aerosol and Cloud Chemistry performs laboratory and field experiments to understand heterogeneous processes associated with aerosol and cloud particles in the atmosphere. This includes processes that directly determine the distribution of both size and chemical composition of aerosols, as well as gas-particle interactions that impact gas phase species. Extensive laboratory studies have investigated the fundamental kinetics and thermodynamics of gas/liquid interactions. Current programs are aimed at developing advanced field measurement techniques for sampling ambient atmospheric particles from ground based and airborne platforms. Measurement methodologies for both particle and gas phase species are based on mass spectrometric methods. CACC has established and maintains a network of collaborators within the US and internationally. Research and development activities are supported by government agencies, private companies and private sector research consortia.

Government sponsors include: the National Science Foundation, the National Aeronautics and Space Administration, the Department of Energy, the Environmental Protection Agency, and the Office of Naval Research.

Private sector sponsors include: the Electric Power Research Institute, the Coordinating Research Council, Air Products, Inc, the Alternative Fluorocarbon Environmental Acceptability Study and the Chemical Manufacturers Association.
