Dr. A.R Ravishankara
A.R. Ravishankara is a professor at Colorado State University in the Departments of Chemistry and Atmospheric Science. He is an Atmospheric Chemist. He was the Director of the Chemical Sciences Division of the NOAA Earth System Research Laboratory until 2013. Dr. Ravishankara's research has contributed fundamental studies of the gas-phase and surface chemistry of Earth's atmosphere, and advanced the understanding of basic chemical processes and reaction rates related to ozone-layer depletion, climate change, and air pollution. For example, his results have led to a better understanding of the chemistry that causes the Antarctic ozone hole, identified new processes that affect ozone pollution in the lower atmosphere, and elucidated the role of aerosols and clouds in climate. Dr. Ravishankara has played leading roles in national and international reports assessing the state-of-the-science understanding of ozone-layer depletion and other issues. He is a co-chair of the Scientific Assessment Panel of the U.N. Montreal Protocol that protects the stratospheric ozone layer. He is a member of the U.S. National Academy of Sciences. His awards include his election as a Fellow of the American Geophysical Union, Fellow of the American Association for the Advancement of Science, Fellow of the United Kingdom Royal Society of Chemistry, recipient of the Polanyi Medal and Centenary lectureship of the Royal Society of Chemistry, the U.S. Environmental Protection Agency's Stratospheric Ozone Protection Award, the Department of Commerce Silver Medal, and the U.S. Presidential Rank Award. He has authored or coauthored over 325 scientific publications. Dr. Ravishankara received his Ph.D. in Physical Chemistry from the University of Florida in 1975.
