Copernicus is the most ambitious Earth observation programme to date. It provides accurate, timely and easily accessible information to improve the management of the environment, understand and mitigate the effects of climate change and ensure civil security. Copernicus is headed by the European Commission (EC) in partnership with the European Space Agency (ESA), who develops, builds, flies and operates the Sentinel family of satellites and missions.
A free, full and open data policy has been adopted by the European Union (EU) for the Copernicus programme. Data Access is available at scihub.copernicus.eu. The licence can be found here (PDF), the Terms and Conditions of the Sentinel Scientific Data hub here. Support is provided at firstname.lastname@example.org.
