Title: Artist concept of Solar Backscatter UV (SBUV) measurement technique on TIROS 
 
Description: 
 
Artist concept titled OZONE MEASUREMENT TECHNIQUE shows how the Solar  
Backscatter Ultraviolet (UV) 2 (SBUV-2) on the National Oceanic and  
Atmospheric Administration's (NOAA's) TIROS satellites (NOAA-9 and NOAA-11)  
works.  Ozone is derived from the "SBUV" instrument from the ratio of the  
observed backscattered radiance to the solar irradiance in the ultraviolet.   
This is called the ultraviolet albedo. During STS-34 Shuttle Solar  
Backscatter Ultraviolet (SSBUV) instruments in Atlantis', Orbiter Vehicle  
(OV) 104's, payload bay (PLB) will calibrate the instruments onboard the  
TIROS satellites.  SSBUV is managed by Goddard Space Flight Center (GSFC).
