The National Environmental Satellite, Data, and Information Service (NESDIS) of the National Oceanic and Atmospheric Administration has been obtaining global ozone information from its current series of polar orbiting operational meteorological satellites. The measurements are made by the Solar Backscatter Ultraviolet Radiometers (SBUV/2) on the NOAA-9 and NOAA-11 satellites.
The SBUV/2 measures incoming solar ultraviolet irradiance and ultraviolet radiance backscattered from the atmosphere; from those measurements it is possible to derive ozone distributions in the sunlit portion of the globe. The ozone measurements include total column amount and vertical distributions over the region 25–55 km above Earth's surface. Ozone observations have been obtained daily from March 1985 with the NOAA-9 instrument. NOAA-11 was launched September 24; operational production of ozone values from NOAA-11 is scheduled to begin in January 1989.
