In recognition of his distinguished scholarly contributions in the atmospheric, hydrologic, and climate sciences, in 1983 Gene Rasmusson was elected as a Fellow of the American Meteorological Society (AMS) and was awarded the AMS Jule G. Charney Award "for major contributions to climate diagnostics, especially of the relationship of the Southern Oscillation to climate anomalies". In 1997 Gene was recognized by the AMS as the Robert E. Horton Lecturer in Hydrology and spoke of "North American Hydrology: The Evolution of an Interdisciplinary Perspective". Subsequently, in 1999 he became a member of the National Academy of Engineering “for contributions to understanding climate variability and establishing the basis for practical predictions of El Nino”. Over the past 25 years Gene has been extremely generous with his time and leadership of the AMS and the National Academies. During this time Gene has served as Editor of the Journal of Climate, Associate Editor of the Monthly Weather Review, Associate Editor of the Journal of Climate Applied Meteorology, Planning Commissioner of the AMS, Member and Chairman of the Awards Committee, and in 1998 was the President of the AMS. In support of activities of the National Research Council (NRC), Gene has served as a member of the NRC Tropical Pacific Panel, TOGA Panel, Committee on USGS Water Research, Panel on Model Assimilated Data sets for Atmospheric and Oceanic Research, Expert Task Group for the Strategic Highway Research Program, Board for Atmospheric Science and Climate, GOALS Panel, and Committee on the Scientific Bases of Colorado River Basin Water Management; and has served has chairman of the Climate Research Committee, and the Committee on the Future of Precipitation Measurements From Space; Phase I: TRMM; Phase II: GPM. This presentation will trace in greater detail Gene Rasmusson's contributions to the American Meteorological Society and the National Academies.
