Show moreThis information release, written by Henry Lansford, notes that the National Hail Research Experiment received a permit from the State of Colorado to conduct the 1973 field research program that spring and summer. A summary of the 5 year project and logistics on the research area (which covers the spot most plagued by hail in the U.S), equipment, and procedure are given. Researchers study the hail storms, seeding half in order to study the effectiveness of cloud seeding as a tool for reducing hail damage. Accomplishments from the first year of field operations, including a new radar method to detect hail and penetrations of hail storms by aircraft, are listed. Show less
