CCOPE was a major field research experiment to study the processes that create convective clouds, rain, hail and high winds over the High Plains of the United States. The CCOPE Records document the logistics and scientific fieldwork of gathering data and studying storms from conception to completion. The collection contains administrative papers, reports, research, daily logs, and papers compiled by Dr. Patrick Squires, Director Convective Storm Division. The materials are entirely in paper format. CCOPE was sponsored primarily by NCAR's Convective Storms Division and the U.S. Department of the Interior's Bureau of Reclamation.
Arrangement is by material subject. The collection consists of four series in three boxes. The contents of each series is in original order. The series arrangement of the records is as follows:
Series I: Administrative, 1979-1983, undated
Series II: Logistics, 1979-1982, undated
Series III: Data, 1981-1983
Series IV: Patrick Squires' Papers, 1975-1983, undated
Biographical or Historical Information
CCOPE was a major field research experiment to study the processes that create convective clouds, rain, hail and high winds over the High Plains of the United States. CCOPE was spurred by the need to assess the potential of weather modification and by the need to improve the prediction of severe thunderstorms and related severe weather. CCOPE was conducted in southeastern Montana at the site of the Bureau‚Äôs High Plains Cooperative Program, a summer sumulous-congestus cloud-seeding project begun in 1976. CCOPE brought together researchers from nearly 30 U.S.¬† and foreign universities and government agencies to study storm processes and meteorological conditions leading to rain or hail. Operations began on May 18, 1981 and comprised coordinated measurements taken from aircraft, radar, and ground-based weather stations, supplemented by rawinsonde and GOES-West satellite data. CCOPE was sponsored primarily by NCAR's Convective Storms Division and the U.S. Department of the Interior's Bureau of Reclamation.
