Copernicus: Sentinel-4 - GEO Component Mission

The Sentinel-4 (S-4) mission within the context of Copernicus represents the geostationary component of European (EC, ESA) operational atmospheric composition monitoring missions.

In December 2007, the GMES Atmospheric Service Implementation Group of the EC (European Commission), issued its preliminary recommendations for the development of the GMES Space Segment operational capabilities in regard of atmospheric missions. In particular, it recommended implementing the Sentinel-4 mission as a UVN (UV/Visible/Near-infrared) sounder to be deployed on the two MTG Sounding (MTG-S) satellites. 1) 2) 3) 4) 5) 6)

Copernicus is the new name of the European Commission's Earth Observation Programme, previously known as GMES (Global Monitoring for Environment and Security). The new name was announced on December 11, 2012, by EC (European Commission) Vice-President Antonio Tajani during the Competitiveness Council.

In the words of Antonio Tajani: "By changing the name from GMES to Copernicus, we are paying homage to a great European scientist and observer: Nicolaus Copernicus (1473-1543). As he was the catalyst in the 16th century to better understand our world, so the European Earth Observation Programme gives us a thorough understanding of our changing planet, enabling concrete actions to improve the quality of life of the citizens. Copernicus has now reached maturity as a programme and all its services will enter soon into the operational phase. Thanks to greater data availability user take-up will increase, thus contributing to that growth that we so dearly need today."
