Division 5 COPERNICUS SPACE COMPONENT DATA DISSEMINATION
United Kingdom
Data dissemination shall cover all activities and functions implementing and supporting the provision of access (‘pull’ service) and/or delivery (‘push’ service) of dedicated mission and contributing mission data to the Copernicus users. The CSC data dissemination shall include:
- (a)
dedicated data access infrastructures;
- (b)
user Services.
The Copernicus data access infrastructure shall implement the Copernicus Data Policy and shall be tailored to the needs of a predefined set of user typologies, namely Copernicus Services, Member States, International partners and other/scientific use. Data access and dissemination infrastructure shall include the following components:
- (a)
Data Access Infrastructure (Sentinel ‘hubs’);
- (b)
Online Data Access (ODA);
- (c)
Copernicus Online Data Access (CODA);
- (d)
Coordinated Data Access System (CDS) for data from contributing Missions;
- (e)
European Data Relay Satellite System (EDRS);
- (f)
EUMETCast;
- (g)
EUMETSAT Data Centre;
- (h)
Data and Information Access Services Infrastructure.
The Copernicus Space Component Data Dissemination systems shall include the available data products as listed in Table 4.

Summary overview of the Copernicus Space Component Data Dissemination Systems
| Data Dissemination System | Description | Available Data Products(current status) |
|---|---|---|
| Sentinel Hubs | Data Access Infrastructure operated by ESA allowing to retrieve Copernicus data for:
| Sentinel-1, Sentinel-2, Sentinel-3 Land |
| Copernicus Online Data Access (CODA) | Data Access Infrastructure operated by EUMETSAT allowing user to retrieve Copernicus data | Near-real time Sentinel-3 Marine, Jason-3 |
| Online Data Access (ODA) | Data Access Infrastructure operated by EUMETSAT allowing Copernicus services and validation team members to retrieve Copernicus data | Near-real time Sentinel-3 Marine, Jason-3 |
| Coordinated Data Access System (CDS) | Data Access Infrastructure operated by ESA allowing user to download data from Contributing Missions. | Contributing Mission Data |
| EUMETCast | Satellite and terrestrial -based multicasting service to deliver Copernicus near real-time EO products operated by EUMETSAT | Near-real time Sentinel-3 Marine, Jason-3 and Contributing Mission data distributed by EUMETSAT |
| EUMETSAT Data Centre | Provision of Copernicus Datasets and Products for the complete mission lifetime, orderable by end users using a search, filter and order mechanism. | Archived Sentinel-3 Marine, Jason-3 and Contributing Mission data distributed by EUMETSAT |
| Data and Information Access Services Infrastructure | Infrastructure that allows users to access, process and analyse Copernicus data and information | Data and Information from the Copernicus Space and Services Component |
The Data Dissemination Systems shall serve different Copernicus user communities; the data available on each of the systems shall be optimised following the needs of those communities.
The ESA Sentinel Hubs shall be tailored to different user typologies (Copernicus Services, Participating States, International Partners and Other). They may differ in their configuration in terms of guaranteed performance, product offer and allowed number of simultaneous downloads.
The Copernicus Services Data Hub shall provide access to all Sentinel products within a specified timeliness (depending upon the product) and availability of the end-to-end service (at least 94 % available for each Sentinel mission constellation). The Collaborative Data Hub and the International Data Hub shall provide access to a rolling archive of Sentinel products with target performances. The Copernicus Open Access Hub shall be configured to avoid resources saturation resulting from massive downloads by a limited number of users.
The Copernicus Data Dissemination Infrastructure shall be continuously updated and improved to cope with the increasing user downloads and expanding data volumes to be distributed.
The User Services shall include features like user registration and management, discovery, view and download services, helpdesk and hosted processing services.
The Copernicus distribution services catalogues shall be interoperable amongst each other and provide complete catalogue information.
Detailed technical descriptions on the Copernicus data dissemination infrastructure and activities shall be made publicly available.
