Design, Fabrication and Flight of an Ultraviolet Interference-Filter Spectrophotometer Aboard a WB57F High Altitude Aircraft.
Abstract
An ultraviolet interference-filter spectrophotometer has been designed, fabricated, and installed on a WB57F high altitude (about 60 kft) aircraft. This instrument (designated the UVS, or UV Spectrophotometer) uses a UV diffuser, ten filters (sets) placed in a rotating wheel, and a high grade ruggedized photomultiplier to provide 12 second time-resolved UV spectra in the region between 200 and 400 nm. The objectives of the UVS are to provide SST altitude UV flux data (1) of aid in interpretation of other, simultaneous measurements made on the aircraft, and (2) for purposes of long term monitoring of geographical and seasonal variations. Results of the first Airstream series on which the UVS was used are reported, and additional atmospheric monitoring applications of the instrument are discussed. (Modified author abstract)
