Total ozone mapping spectrometer

From Glossary of Meteorology

Total Ozone Mapping Spectrometer

(Abbreviated TOMS.) A satellite instrument that measures backscattered ultraviolet radiation to infer total column ozone.

TOMS was first flown on ''Nimbus''-7, launched in November 1978, and has subsequently flown on ''Meteor''-3, ''ADEOS'', and other international satellites. The antarctic ozone hole was first discovered through analysis of TOMS data.
