Air Force Cambridge Research Laboratories conducted two field programs at the White Sands Missile Range to obtain experimental data for the Climatic Impact Assessment Program of the Department of Transportation. These data provide a prediction of the residence time and behavior of exhaust products deposited by supersonic aircraft in the stratosphere. The data were obtained by photographing smoke trails from rockets and aircraft dispensing systems. This report describes the development and flight results of (1) the rocket dispensing system, designed to produce vertical smoke trails over the 12- to 25-km region, and (2) the aircraft dispensing system, designed to produce horizontal trails at 16- and 20-km altitudes.

This report describes some recent improvements in the hardware and software used to measure photographic images of chemical smoke trails. It also presents measurements of winds and windshears for five experiments conducted at White Sands Missile Range and Wallops Island from 1973 to 1978. In addition, it discusses sources of error in the measurements and suggests means of reducing the errors to improve the vertical resolution of the wind and windshear profiles.
