Summary
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 data consists of daily
gridded averages of total ozone covering the entire globe. The
... original Nimbus-7 TOMS operated from November 1978 until May
1993. Meteor-3 TOMS was launched in August 1991 and operated until
December 1994.

After a gap of one and a half years, two new TOMS instruments began
operation in 1996: Earth-Probe TOMS was launched on 2nd July 1996 and
started to produce data on 25th July. ADEOS TOMS was launched on 17th
August 1996 and started producing data on 11th Sept. The satellites
were originally placed in different orbits, giving complete global
coverage with the ADEOS data, while Earth-Probe had complete coverage
at the poles with an increased ability to measure UV-absorbing
aerosols in the troposphere. ADEOS failed in June 1997 and Earth-Probe
was subsequently placed in a higher orbit to give global
coverage. Earth-Probe TOMS continues to operate successfully.
