Total Ozone Mapping Spectrometer

Near-global ozone for September 6, 2004, by TOMS-EP

The Total Ozone Mapping Spectrometer (TOMS) is a NASA satellite instrument for measuring ozone values. Of the five TOMS instruments which were built, four entered successful orbit. Nimbus-7 and Meteor-3-5 provided global measurements of total column ozone on a daily basis and together provided a complete data set of daily ozone from November 1978 to December 1994. After an eighteen-month period when the program had no on-orbit capability, ADEOS I was launched on August 17, 1996, and provided data until the satellite which housed it lost power on June 29, 1997. TOMS-Earth Probe was launched on July 2, 1996, to provide supplemental measurements, and was later boosted to a higher orbit to replace the failed ADEOS I. The only total failure in the series was QuikTOMS, which was launched on September 21, 2001, but did not achieve orbit.[1] The transmitter for TOMS-Earth Probe failed on December 2, 2006.[2]

Since January 1, 2006, data from the Aura Ozone Monitoring Instrument (OMI) has replaced data from TOMS-Earth Probe.[3] The Ozone Mapping and Profiler Suite on Suomi NPP and NOAA-20 have further continued the data record.
