GOME-2 instrument
The Global Ozone Monitoring Experiment-2 (GOME-2) is one of the new-generation European instruments carried on Metop and will continue the long-term monitoring of atmospheric ozone started by GOME on ERS-2 and SCIAMACHY on Envisat. The more advanced GOME-2 is set to make a significant contribution towards climate and atmospheric research, whilst providing near real-time data for use in air quality forecasting.
