Professor Pandis' research areas include the study of multiphase atmospheric chemistry as it relates to photochemical smog and acid deposition, as well as topics related to global climate change.
Control Strategies for Atmospheric Ozone, Particulate Matter, and Acidity
Air pollution problems have been traditionally treated separately from each other, often resulting in sub-optimal choices of emission control strategies. The air pollution group is developing comprehensive mathematical models describing the interplay of pollutant emissions, atmospheric homogeneous and heterogeneous chemistry, dispersion, and removal processes leading to major air pollution problems. After evaluation against observations, these tools are used for the identification of cost-effective emission controls for the reduction of damages caused by multiple pollutants.
Atmospheric Chemistry and Global Climate Change
The interactions between the anthropogenic perturbations of the atmospheric chemical composition and climate are investigated in a number of projects. These include studies of the role of atmospheric aerosols in the earth's radiative balance, changes in the oxidative capacity of the atmosphere, the anthro-pogenic perturbations in the remote marine atmosphere, and the long range transport of atmospheric trace components.
Properties of Atmospheric Aerosols
The partitioning of semi-volatile atmospheric aerosol components between the gas and particulate phases is investigated. The role of the organic aerosol components on the ability of atmospheric particles to absorb water is a major focus of this research.
