Enhanced Water Recovery from Clouds:  Is it Possible?

Bart Geerts

University of Wyoming
Department of Atmospheric Science

Since the late 1940s, scientists have tinkered with clouds to enhance precipitation from them. For decades, clouds over mountains in the western USA and elsewhere have been seeded, mainly with dust particles that facilitate ice crystal formation. The State of Wyoming has almost completed a long-term weather modification study centered over the mountain ranges just west of Laramie, a study recognized internationally as the most ambitious and most thorough ever. We explore the thinking behind cloud seeding, the evidence that has driven ongoing commercial seeding, and new insights gained in Wyoming.   
Dr. Bart Geerts conducts research into cloud-scale to mesoscale atmospheric processes, mainly using aircraft measurements and radar.  He has taught several graduate-level and undergraduate-level courses for the Department of Atmospheric Science at the University of Wyoming, and also in Australia and Europe.  Dr. Geerts received his PhD from the University of Washington (Atmospheric Science, 1990), and MS and BS degrees from the University of Louvain in Belgium, his country of origin.  He (co-)authored one textbook and some 70 peer-reviewed journal papers, most of them with graduate students at the University of Wyoming.  Dr. Geerts has served on review panels for several federal agencies and chaired several conference committees of the American Meteorological Society. In 2012 he received the National Institutes for Water Resources Program IMPACT Award, which recognizes the nation's best federal research projects funded by the United States Water Resources Research Act.
