GOMOS
(Global Ozone Monitoring by Occultation of Stars)

The Global Ozone Monitoring by Occultation of Stars (GOMOS) Instrument on board Envisat is the newest ESA instrument aiming at ozone monitoring. It is a tool to provide altitude-resolved global ozone mapping and trend monitoring with very high accuracy, as needed for the understanding of ozone chemistry and for model validation. The primary GOMOS mission objectives are:

• Measurement of profiles of ozone, NO2, NO3, OClO, temperature, and water vapor;
• Day- and night-side measurement capability;
• Global coverage with typically over 600 profile measurements per day;
• Altitude measurement capability between the tropopause and 100 km;
• Altitude resolution of better than 1.7 km.
