“Are Extreme Precipitation Events Increasing in the United States?”

David Legates, Ph.D., is professor of climatology in the Department of Geography at the University of Delaware, and an adjunct professor at the university’s Physical Ocean Science and Engineering Program, and the Department of Applied Economics. Legates has argued for the necessity of technological progress in precipitation measurement used for validating climate change scenarios, and for validation of existing data used for that purpose. He co-developed methods to correct bias in gauge-measured precipitation data for wind and temperature effects, with direct applicability in climate change, hydrology and environmental impact studies. Legates also developed a calibration method which validates NEXRAD radar precipitation data with gauge measurements to improve the accuracy of precipitation estimates. He has earned the certified consulting meteorologist status from the American Meteorological Society, and in 1999 was awarded the Boeing Autometric Award for best paper in image analysis and interpretation. Legates has published more than 125 articles in refereed journals, conference proceedings, and monograph series and has made more than 250 professional presentations
