physics from Dickinson College, Carlisle, Pennsylvania, and his Ph.D. in Meteorology from Pennsylvania State University.

Lynne D. Talley is a Professor of Oceanography at the Scripps Institution of Oceanography at the University of California, San Diego. Dr. Talley’s expertise and research interests lie in general ocean circulation, hydrography, theory of wind-driven circulation, and ocean modeling. Dr. Talley has an extensive NRC committee background, serving currently on the Climate Research Committee and previously on the Global-Ocean-Atmosphere-Land System Panel and the Panel to Review the Jet Propulsion Laboratory Distributed Active Archive Center (DAAC). She is a UCAR trustee, a councilor of The Oceanography Society, and co-chair of the U.S. Repeat Hydrography Oversight Committee. She is a fellow of the American Academy of Arts and Sciences. Dr. Talley was a National Science Foundation Presidential Young Investigator in 1987 and was awarded the Rosenstiel Award in 2001 and the Huntsman Award in 2003.

Paul D. Try is Senior Vice President and Program Manager at Science and Technology Corporation (STC) and recent past Director of the International Global Energy and Water Cycle Experiment (GEWEX) Project Office. He received his Ph.D. in atmospheric sciences from the University of Washington. Dr. Try has expertise in meteorological in-situ and remote sensors (satellite and radar), as well as data collection, processing, exchange and archival activities. Prior to joining STC, he served in the U.S. Air Force and the Office of the Secretary of Defense where he provided oversight management of all DOD research and development in environmental sciences. Dr. Try is a fellow of the American Meteorological Society (AMS) and was president of the AMS in 1996-97. He previously served on two NRC Committees, the Committee on NOAA NESDIS Transition from Research to Operations and the Committee on Status and Future Directions in U.S. Weather Modification Research and Operations, and he currently is a member of the NRC’s Committee on Climate Data Records from Operational Satellites: Development of a NOAA Satellite Data Utilization Plan.

Hassan Virji is Deputy Director for Global Change System for Analysis, Research and Training (START), an international nongovernmental organization sponsored by the Earth Systems Science Partnership affiliated with the International Council for Science (ICSU). He has served as Executive Secretary of the U.S. Subcommittee on Global Change Research while based at the National Science Foundation (NSF), as Deputy Executive Director of the International Geosphere-Biosphere Programme, as Associate Program Director of the Climate Dynamics Program of the NSF, and on the faculty of the University of Nairobi, Kenya. Dr. Virji received his Ph.D. in Meteorology from the University of Wisconsin. He is a member of the NRC’s Board on International Scientific Organizations and currently serves on the Climate Research Committee.


Julie Demuth is a Program Officer for the Board on Atmospheric Sciences and Climate. She received her B.S. in meteorology from the University of Nebraska-Lincoln and her M.S. in atmospheric science from Colorado State University. Her master’s research focused on developing techniques for objectively estimating the intensity and wind structure of tropical cyclones in the Atlantic and East Pacific basins using Advanced Microwave Sounding Unit data. The intensity estimation algorithm now is being run operationally by NOAA’s National Hurricane Center during the tropical season. Since joining BASC in March 2003, Julie has worked on studies involving atmospheric dispersion of hazardous materials, weather modification, road weather research, and using NEXRADs sited in complex terrain for flash flood forecasting.

Rob Greenway has been a project assistant at the National Academies since 1998. He received his A.B. in English and his M.Ed. in English education from the University of Georgia.
