Walt Dabberdt, an AMS Member, a Fellow of the AMS, and the AMS President for 2008, is Corporate Science Adviser for Vaisala. He is based at Vaisala's Boulder Operations in Louisville, Colorado. Dr Dabberdt was born in Brooklyn, New York and has resided in Boulder, Colorado since 1985. He has a BS degree from the State University of New York Maritime College with joint majors in marine transportation and meteorology, and he has MS and PhD degrees in meteorology from the University of Wisconsin—Madison. Dr Dabberdt joined Vaisala in 2000, where he has previously held the positions of Director of Strategic Research and Chief Science Officer. Prior to joining Vaisala, he spent 15 years at the National Center for Atmospheric Research as scientist, observing technology facility manager, and NCAR Associate Director (the de facto chief operating officer). Previously for 15 years Dr. Dabberdt was a senior research meteorologist at the Stanford Research Institute, (now SRI International). His professional interests and experience include terrestrial observing systems, boundary-layer and mesoscale meteorology, air quality, fluid modeling, urban-scale meteorology and dispersion. Dabberdt was awarded a postdoctoral fellowship from the National Research Council, Dr Dabberdt was awarded a postdoctoral fellowship from the United States National Research Council, working on atmospheric turbulence and energy exchange processes in the Antarctic Plateau. He was also awarded a research fellowship from the Alexander von Humboldt Foundation exploring atmospheric dispersion of vehicular emissions as well as remote sensing methods for quantifying air-surface exchange processes in urban areas while at the University of Munich. Dr Dabberdt has served on numerous national and international panels and committees. He was a member of the National Academy of Sciences' Board on Atmospheric Sciences and Climate. During that time he also chaired the BASC study panel that authored the widely cited report When Weather Matters: Science and Services to Meet Critical Societal Needs. Dr Dabberdt also served on various other NRC study committees that focused on dispersion of hazardous materials, research management and peer review at the Environmental Protection Agency, and earth science and applications from space (the so-called decadal survey). He was Board Chair of the Environmental Prediction in Canadian Cities (EPiCC) research program that was supported by the Canadian Foundation for Climate and Atmospheric Sciences. Dr Dabberdt was a member of the International Science Steering Committee for the World Meteorological Organization's GURME Shanghai Air Quality Forecasting Program and Chair of the International Science Advisory Committee for the WMO GURME Workshop on Urban Meteorological Observation Design. He also served as Co-Chair of the WMO THORPEX Observing Systems Working Group, and was twice a member of the US Delegations to the WMO Congress and the WMO Executive Council meetings. Board Chair of the Environmental Prediction in Canadian Cities research program; Chair of the Industrial Advisory Board of the multi-university Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere; Chair of the NCAR Earth Observing Laboratory's External Advisory Committee; member of the International Science Steering Committee for the World Meteorological Organization GURME Shanghai Air Quality Forecasting Program; Co-Chair of the NOAA Science Advisory Board Environmental Information Services Working Group; member of the NCAR Director's Advisory Committee; and member of the Dean's Advisory Board to the College of Engineering at Colorado State University. Dr Dabberdt is a Fellow of the Royal Meteorological Society. He has been recognized as a lifetime National Associate of the National Research Council of the National Academies.
