The 1968 Grand River Project - A Trial Project in Precipitation Management,
Abstract
The report describes the 1968 Grand River Project, a trial program in precipitation management conducted in northwestern South Dakota. The project objectives included the gaining of experience in cloud seeding under operational conditions and the testing of effects of heavy silver iodide seeding upon rainfall and hailfall in and downwind of a designated target area. Randomization was not employed. Aircraft seeding was used exclusively, with three aircraft available. Approximately 210 hr of flight time were logged on seeding missions. Seeding devices included pyrotechnics and acetone generators. Analyses of rainfall and hailfall data collected in connection with the project are given. (Author)
