Delivering the marine and atmospheric composition missions for Copernicus.
Sentinel satellite series
Dedicated Copernicus satellite mission delivering a variety of high-quality ocean measurements.
Copernicus Sentinel-4 will monitor key air quality trace gases and aerosols over Europe at high spatial resolution.
The Sentinel series of satellites and instruments provide a vital contribution to Europe’s Copernicus Earth monitoring system.

EUMETSAT is responsible for operating the Copernicus Sentinel-3 and Sentinel-6 ocean monitoring satellites and will also operate and deliver products from the Sentinel-4, and Sentinel-5 instruments on board Meteosat Third Generation (MTG) and Metop - Second Generation (Metop-SG), respectively.
The Copernicus Sentinel-3A and -3B satellites collect observations of global ocean colour, sea surface temperature and sea surface height. EUMETSAT’s role is to operate the satellite, in cooperation with ESA, and deliver the marine data on behalf of the EU. ESA delivers the land data.
Instruments on board the satellite will also collect high resolution vertical profiles of temperature, using the GNSS Radio Occultation sounding technique, to assess temperature changes in the troposphere and stratosphere and to support Numerical Weather Prediction.
The mission is co-funded by the European Commission, the European Space Agency, EUMETSAT and the US, through NASA and the National Oceanic and Atmospheric Administration (NOAA).
Sentinel-4 and 5 instruments
The Sentinel-4 instrument, on board MTG, will monitor air quality over Europe every hour at high spatial resolution, while Sentinel-5, on board Metop-SG, will monitor global air quality and climate-related trace gases and aerosols in the Earth’s atmosphere.

The Earth observation satellites which provide the data used by the Copernicus services are split into two groups of missions: the Sentinels and the Contributing Missions.
EUMETSAT is responsible for operating the Sentinel-3 satellites and delivering the marine mission, as well as operating and delivering products from the future Sentinel-4 instrument on board the MTG satellites and the Sentinel-5 instrument, on board the ESP-SG satellites, and the Sentinel-6 Michael Freilich satellites. EUMETSAT also operates the Copernicus contributing mission, Jason-3, and distributes data from other contributing missions operated by international agencies.
Altimetry data is used to determine sea level height, wind speed and wave height.
The Copernicus Sentinel-3 mission includes key optical instruments monitoring the composition of our atmosphere.
Ocean colour services
Providing information on ocean living ecosystems, water quality and sediment dynamics.
