Info about Data Access from EC Copernicus Website

Depending on their needs, users can obtain these data either from the Copernicus services or directly from the Copernicus satellites.

Access to Sentinel-1A data
Data from the first Copernicus satellite (Sentinel-1A) launched on 3 April 2014 are available here.

Access to Copernicus satellites data (general)
Users interested in data coming directly from the Copernicus space component (the Sentinels satellites) can access them through the Sentinel Online portal operated by the European Space Agency (A specific section is dedicated to “Data Access” on this portal).

No registration is required for discovery and view services while it is a prerequisite to download Sentinel data. Registration is free of charge.


In addition to the data produced by the Sentinels satellites, Copernicus users can also have access under certain conditions to the data produced by other satellite missions referred to as Contributing Missions. Contributing Missions have been classified into five groups that reflect the characteristics of the main types of missions.

Most data provided by the different contributing missions are distributed by the European Space Agency (ESA). They take the form of datasets and are delivered to users through data access services. The delivery process relies on an operational system called the Coordinated Data access System (CDS).

Other space-based data are provided by the French Space Agency (CNES) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).

Access to Copernicus services data

Data are available through the web portals operated by the various Copernicus service lines:

Land-related data
Atmosphere-related data
Marine-related data
Emergency-related data

(Data are not yet available online for the Climate Change service and for Security applications, which are still in a development phase).

For the Land-, Atmosphere- and Marine-related services, anyone can have access to data but registration is mandatory. Registration is free-of-charge.


For the time being, there is no common registration facility. Users interested in data coming from several web portals must therefore register on each web portal.

For the Emergency Management service, data production can be triggered only by “authorized users” but the maps produced by the service are available on the service web portal and can be downloaded without registering.
