Total ozone monitoring satellite

From Glossary of Meteorology



Total Ozone Monitoring Satellite

Satellite-borne spectrometer for measuring the total column amount of ozone above the earth.

The spectrometer works by measuring the amount of ultraviolet radiation scattered back into space at several wavelengths. Data from TOMS have been invaluable in evaluating long-term trends in global ozone and also annual events such as the antarctic ozone hole.
