The Total Ozone Mapping Spectrometer (TOMS) is an instrument built and operated by the National Aeronautics and Space Administration (NASA). The instrument uses backscattered ultraviolet radiance to infer total column ozone measurements. The dataset consists of daily gridded averages of total ozone covering the entire globe, in the form of images, from NASA NIMBUS 7, Meteor-3, Earth Probe and ADEOS satellites. Data is from 1978 to 2006. The Ozone Monitoring Instrument (OMI) on the AURA spacecraft, OMI data of ozone are now available for the entire OMI mission. In addition to ozone data, OMI data for aerosol and reflectivity are available. These datasets are public.

Total Ozone Mapping Spectrometer (TOMS) data were mirrored from GSFC NASA until saturday December 2, 2006, when contact with Earth Probe was lost.
Data quality controlled by NASA. TOMS - Total Calibration Error - The Version 8 algorithm is now used for all TOMS data. For data beginning in year 2000, the calibration has been stabilized relative to NOAA-16 SBUV/2 in the equatorial zone. Because of continuing changes in the optical properties of the front scan mirror that are not well understood, we are now seeing a latitude dependent error that cannot be corrected by a simple calibration correction. The calibration appears to be stable near the equator. But by 50 degrees latitude, there is now a -2% to -4% error in TOMS, a bit larger in the northern hemisphere than in the southern hemisphere. Because of this error, data since 2002 should NOT be used for trend analysis.

|Abstract||This computation involved: DETAILS NEEDED - COMPUTATION CREATED FOR SATELLITE COMPOSITE. deployed on Advanced Earth Observing Satellite (ADEOS). Advanced Earth Observing Satellite (ADEOS) was the first international space platform dedicated to Earth environmental research developed and managed by the National Space Development Agency of Japan (NASDA). The TOMS instrument along with NSCAT (a NASA Spectrometer designed to study wind speed and direction) were major US components of the platform. ADEOS launched on August 17, 1996 (at 01:53 UT) into a sun synchronous sub-recurrent orbit of an altitude of approximately 830 km by an H-II launch vehicle from the Tanegashima Space Center. ADEOS failed in June 1997|
