STRATCOM - VI-A (Stratospheric Composition)

Balloon launched on 9/23/1975, from Holloman Air Force Base, Alamogordo, New Mexico, US

Purpose of the flight and payload description

STRATCOM (STRATospheric COMposition) was a long-term, multi-purpose program for integrated, correlated measurements of stratospheric parameters related to composition, thermodynamics, and radiative balance. It was a joint undertaking of several laboratories whose combined scientific, engineering, and field capabilities made possible an extensive program of multiple related measurements in the very complex and variable stratosphere. The program was born in 1968 by the initiative of the US Army's Atmospheric Sciences Laboratory (ASL), under the direction of Harold N. Ballard. Starting from the third mission in 1972, the program progresively incorporated other research institutions. A total of eight balloon flights were performed until the culmination of the effort in 1977.
