Data coverage
The Shuttle Solar Backscatter Ultraviolet (SSBUV) Level-2 Ozone data are available for eight space shuttle missions flown between 1989 and 1996. SSBUV, a successor to the SBUV flown on the Nimbus-7 satellite, is nearly identical to the SBUV/2 instruments flying on the NOAA satellites. Data are available in the ASCII AMES text format. Ozone profiles of the upper atmosphere and total column ozone values are available for the following time periods: Flight 1: 1989 October 19, 20, 21. Flight 2: 1990 October 7, 8, 9. Flight 3: 1991 August 3, 4, 5, 6. Flight 4: 1992 March 29, 31. Flight 5: 1993 April 9, 11, 13, 15, 16. Flight 6: 1994 March 14, 15, 17. Flight 7: 1994 November 5, 7, 10, 13. Flight 8: 1996 January 12, 16, 18. SSBUV measures spectral ultraviolet radiances backscattered by the earth's atmosphere. For the ozone measurements the instrument steps over wavelengths between 252.2 and 339.99 nm while viewing the earth in the nadir position (50 km x 50 km footprint at nadir) at 19 pressure levels between 0.3 mb and 100 mb. SSBUVIRR The Shuttle Solar Backscatter Ultraviolet (SSBUV) level-2 irradiance data are available for eight space shuttle missions flown between 1989 and 1996. SSBUV, a successor to the SBUV flown on the Nimbus-7 satellite, is nearly identical to the SBUV/2 instruments flown on the NOAA polar orbiting satellites. Data are available in an ASCII text format. UV irradiance data are available for the following days from the eight missions: Flight 1: 1989 October 19, 20, 21 Flight 2: 1990 October 7, 8, 9 Flight 3: 1991 August 3, 4, 5, 6 Flight 4: 1992 March 29, 30 Flight 5: 1993 April 9, 11, 13, 15, 16 Flight 6: 1994 March 14, 15, 17 Flight 7: 1994 November 5, 7, 10, 13 Flight 8: 1996 January 12, 16, 18 The Shuttle SBUV (SSBUV) instrument measured solar spectral UV irradiance during the maximum and declining phase of solar cycle 22. The SSBUV data accurately represent the absolute solar UV irradiance between 200-405 nm, and also show the long-term variations during eight flights between October 1989 and January 1996. These data have been used to correct long-term sensitivity changes in the NOAA-11 SBUV/2 data, which provide a near-daily record of solar UV variations over the 170-400 nm region between December 1988 and October 1994. These data demonstrate the evolution of short-term solar UV activity during solar cycle 22.
