New generation of GOME instruments

Following the successful mission of the Global Ozone Monitoring Experiment (GOME) on-board the European Space Agency (ESA) ERS-2 satellite, the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) and ESA have decided to embark on-board the Metop satellites an improved version of the GOME spectrometer. The new generation of GOME instruments will provide data for the ozone product chain of the EUMETSAT Polar System, in charge not only of the daily production of ozone data but also of the long term ozone monitoring. This imposes strong accuracy and stability requirements to the instrument, the calibration activities and the ground processing.
