NHRE: National Hail Research Experiment

Summary

The National Hail Research Experiment (NHRE) was a multiyear project aimed at determining the usefulness of cloud seeding for the reduction of damaging hailfall. The project consisted of randomized seeding experiments in the plains of northeast Colorado during the summers of 1972 - 1974, data analysis in 1975, an additional field phase in 1976, and incorporation into NCAR's research program thereafter. In addition to the cloud seeding experiments a variety of related studies took place that focused on the microphysics and dynamics of hail formation, the forecasting value of numerical models, and the societal impacts of hailfall and cloud seeding.
