Department of Atmospheric Science Professor Bart Geerts will discuss the latest scientific information on the effectiveness of cloud seeding during the spring Faculty Senate Speaker Series talk Wednesday, April 16, at 4:10 p.m. in Room 306 of the University of Wyoming Classroom Building. The talk is free and open to the public.

Geerts, who for many years has used aircraft measurements and radar to study atmospheric processes, will discuss “Enhanced Water Recovery from Clouds: Is it Possible?” He has contributed to a major cloud seeding study in the Medicine Bow and Sierra Madre mountains in southern Wyoming.

“For decades, clouds over mountains in the western United States and elsewhere have been seeded, mainly with dust particles that facilitate ice crystal formation,” says Geerts. ”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.”

Geerts has taught several graduate and undergraduate courses at UW and also in Australia and Europe. He co-wrote one textbook and is credited with nearly 70 peer-reviewed journal papers, most of them with UW graduate students. He has served on review panels for several federal agencies and chaired several American Meteorological Society conference committees.

In 2012, Geerts 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. Geerts received his doctorate in atmospheric science (1990) from the University of Washington and received M.S. and B.S. degrees from the University of Louvain in Belgium, his home country.
