Free ESA Data

ESA has defined a new Earth Observation Data Policy which was approved by the ESA Earth Observation Programme Board in May 2010. The new data policy applies to the ESA missions, i.e. to ERS-1, ERS-2, Envisat, GOCE, SMOS, CryoSat and future Earth Explorer missions. It is derived from the full and open access approach established in the Sentinel Data Policy.

The free dataset includes the dataset collections available on-line. A user registration is needed for accessing the free dataset. Data access is provided in 2-3 working days after registration.
