STRATCOM VIII EFFORT.

The Stratcom program has been conducted around the concept of a multiparameter study of the stratosphere using various sensors and platforms as appropriate. In the Stratcom VIII effort of September 1977, scientists and engineers from about 20 organizations used nearly 40 kinds of instruments to investigate the stratosphere. The principal objective was to obtain data related to atmospheric photochemistry. This report summarizes the effort, describing balloon, rocket, and aircraft operations; includes detailed lists of organizations, instruments, and parameters; and presents discussions by each participant concerning his experiment and results. Measurements were made of ozone content, solar ultraviolet spectral flux, nitric acid overburden, temperature, aerosol sizes, water vapor content, electron content, positive and negative conductivities, and characteristics of the boundary layer associated with a large balloon and its payload.
