Concept information
Preferred term
BUV
Definition
- The backscatter ultraviolet instrument (BUV) monitored the spatial distribution of atmospheric ozone by measuring the intensity of the UV radiation backscattered from the earth's atmosphere. To obtain this ozone distribution, the BUV subsystem measured direct solar radiation and backscattered UV radiation from the daytime sun-illuminated atmosphere. The Instrument consisted of a spectrometer (monochromatic) and a photometer. The monochromatic measured the intensity of UV radiation backscatter and reflected radiation from the earth's atmosphere in 12 wavelengths (2555 to 3398 A) in which ozone attenuation occurs. The photometer measured the reflected UV radiation in a single wavelength span in which attenuation by ozone does not occur. The BUV had four operating modes. [Summary provided by NASA] (en)
