Ladies and gentlemen, it gives me great pleasure to introduce Dr. Thomas J. Jackson, of the United States Department of Agriculture, for the 2003 Hydrology Award. Tom got his B.S. in fire protection engineering, his M.S. in civil engineering, and a Ph.D. under Bob Ragan at the University of Maryland in 1976. He has been a research hydrologist with the USDA Agricultural Research Service Hydrology and Remote Sensing Lab since 1977. His research involves the application and development of remote sensing technology in hydrology and agriculture. These studies have ranged from small-scale controlled condition field experiments utilizing truck-mounted radiometers to large-scale multitemporal aircraft mapping and most recently satellite retrievals.
