National Hail Research Experiment

Project Description
The National Hail Research Experiment (NHRE), funded by the National Science Foundation (NSF) and managed by the National Center for Atmospheric Research (NCAR), began studying hailstorms over northeastern Colorado, southwestern Nebraska, and southeastern Wyoming in the summer of 1971, working from a radar facility and field headquarters near the little town of Grover, Colorado. From 1972 through 1974, the NHRE field research program included randomized cloud seeding during the peak hail season, along with convective storm research using instrumented aircraft, radar, a precipitation network on the ground, and a variety of other research tools and facilities. The randomized seeding experiment was discontinued at the end of the 1974 hail season, and the most recent NHRE field work was an intensive observational program conducted during the summer of 1976.
