3 European Space Agency cooperation in space ESA is an intergovernmental organisation with 22 Member States ESA purpose: provide for and to promote, for exclusively peaceful purposes, cooperation among European States in space research and technology and their space applications... Article II of the ESA convention ESA achieves this through: Space activities and programmes Implementing a long term space policy A specific industrial policy Coordinating European with national space programmes 08/2005-2

4 Sentinels watching over Agriculture

5 Sentinels New Era of Observations EU-ESA Copernicus Space Programme Long-term Continuity & Access to Earth Observation data (*) Sentinel 1 SAR imaging All weather, day/night application e.g. crop type, floods, water bodies 2014 & 2016 Sentinel 2 Multi-spectral imaging Land applications: urban, forest, crop status & type Continuity of Landsat, SPOT 2015 & 2017 Sentinel 3 Ocean & global land monitoring Wide-swath ocean color, global vegetation, evapotranspiration, land/sea surface temperature, altimetry 2016 & 2017 * Joint EU/ESA Data Policy Principles adopted by ESA member states in Sep 09, EU announced in Nov. 2013
