Research Interests

My research concentrates on two areas. One concerns theoretical and modeling studies of climate feedback mechanisms that can either amplify or diminish global climate change. A quantitative understanding of such mechanisms is a prerequisite to being able to project climate change caused by anthropogenic factors such as increasing greenhouse gases.

The second research area augments the first and concerns the acquisition and interpretation of both surface and satellite radiometric data. Thus, I have been involved with NASA’s Earth Radiation Budget Experiment; their subsequent Clouds and the Earth’s Radiant Energy System, which is part of the Earth Observing System; and DOE’s Atmospheric Radiation Measurements Program. The focus of these observational programs is to obtain a better understanding of how clouds impact the present climate, so as to improve our capability of predicting how clouds impact climate change.
