The Meteor craft are weather observation satellites launched by the USSR. The Meteor satellites were designed to monitor atmospheric and sea-surface temperatures, humidity, radiation, sea ice conditions, snow-cover, and clouds.-Meteor 2-21:...
provided global measurements of total column ozone on a daily basis and together provide a complete data set of daily ozone from November 1978 - December 1994. After an eighteen month period when the program had no on-orbit capability, ADEOS TOMS was launched on August 17, 1996 and provided data until the satellite which housed it lost power on June 29, 1997. Earth Probe TOMS was launched on July 2, 1996 to provide supplemental measurements, but was boosted to a higher orbit to replace the failed ADEOS. The only total failure in the series was QuikTOMS-satellite, which was launched on September 21, 2001 but did not achieve an orbit. The transmitter for the Earth Probe TOMS failed on December 2, 2006.http://toms.gsfc.nasa.gov/news/news.html#mar05
Since January 1, 2006 data from the Ozone Monitoring Instrument
Ozone Monitoring Instrument
OMI The Ozone Monitoring Instrument is on board the NASA Aura. OMI can distinguish between aerosol types, such as smoke, dust, and sulfates, and can measure cloud pressure and coverage, which provide data to derive tropospheric ozone. OMI follows in the heritage of TOMS, SBUV, GOME, SCIAMACHY, and...
