The service, which is operated by Mercator Ocean International, provides regular information on the physical state, variability and dynamics of the ocean and marine ecosystems for the global ocean and the European regional seas.

The products and forecasts it delivers support four main application areas, marine resources, marine safety, coastal and marine environment and weather, climate and seasonal forecasting.

What is EUMETSAT's role?

EUMETSAT delivers a range of ocean products to CMEMS and its user community. This includes data and products from EUMETSAT's Metop and Meteosat satellite series, and from missions of EUMETSAT’s international partners.

After the successful launches of Sentinel-3A (16 February 2016) and Sentinel-3B (on 25 April 2015), EUMETSAT’s role is to operate the satellites, in cooperation with ESA, and deliver the marine data (ocean colour, sea surface temperature and sea surface topography) on behalf of the EU.

EUMETSAT is also delivering data to Copernicus from the Jason-3 ocean altimetry satellite. Jason-3 is the result of an international partnership between EUMETSAT, CNES, NOAA, NASA and the European Union, which funds European contributions to Jason-3 as part of the Copernicus programme.

Jason-3 is the fourth in the series of US/European ocean altimetry satellites that together have built up a time series of global mean sea level that dates back to 1992. 


Jason data provide the indispensable reference against which measurements of all other altimeter missions (e.g. Sentinel-3) can be cross-calibrated

The follow on from Jason-3 is the Copernicus Sentinel-6 mission which will be implemented by two successive Sentinel-6 high-precision radar altimetry satellites. These satellites will be operated by EUMETSAT and will continue the high accuracy ocean surface topography measurements of Jason-3.

EUMETSAT will deliver marine data and support services from a constellation of ocean monitoring satellites until 2035 - including Sentinel-3, Jason-3 and Sentinel-6 and also from its own satellite missions.
