Historic Quotations on Evaluations of Cloud Seeding Programs


  • Tom Henderson Atmospherics Incorporated


Cloud seeding programs designed to augment precipitation by enhancing the natural precipitation processes began in the late 1940’s following the early discoveries of Drs. Irving Langmuir, Vincent Schaefer and Bernard Vonnegut, a trio of dedicated scientists working at the General Electric Research Laboratory in Schenectedy, New York. This past season there were 16 programs active in California, substantial programs in six other states, and a broad range of programs in 60 additional countries. From the serious and extensive evaluations of many cloud seeding programs, a few examples of the conclusions are presented in the following quotations from a cross section of historic publications.
