Abstract

A prototype of the balloon borne ozone profiler with variable footprint has been developed and was flown from Fort Sumner, New Mexico and September 30, 1992. The instrument was composed of a 100 mm grating spectrograph with an intensified diode array detector covering a spectral range from 250 nm to 350 nm. Scanning of the horizon was accomplished with a right angle dichroic mirror driven by a stepper motor. The viewing direction was determined by a shaft encoder on the scanning mirror and a magnetic compass fixed to the balloon gondola. Altitude was determined using a global positioning system (GPS) receiver.
