WEkEO is one of the 5 Copernicus DIAS (Data and Information Access Services). The overarching objective of DIAS is to enhance access to Copernicus data and information for further use in an efficient computing environment implementing the paradigm of “bringing the user to the data”, as one condition for unlocking the potential value of Copernicus for innovation, science, new business, implementation of public policies and economic growth.

Considering the well-structured user communities and the strong relationship existing between EUMETSAT, Mercator-Océan and ECMWF, Copernicus ClimateChange Service, the organisations have joined their efforts to implement one instance of DIAS in partnership, namely WEkEO. WEkEO is the service for marine environmental data, virtual environments for data processing, and skilled user support. WEkEO will have a public and free part for discovery and access to data and data products, while it will also have a commercial part with various analysis applications and cloud space.

Type & number of data sets

The Harmonized Data Access (HAD) will have a single access protocol (REST API) whereby scaling and evolution of codes will be made easy. It will provide easy & fast access to subsetting attributes in hundreds of datasets from difference Copernicus sources and allow uniform access to the whole WEkEO catalogue, including subsetting and downloading functionalities. The HAD will provide discovery and access to:

  • All the Sentinel satellite data sets: S1, S2, S3 Marine, S3 Land, S5P
  • Main Copernicus Service Data products from:
    • Copernicus Marine Service: CMEMS
    • Copernicus Atmospheric Service: CAMS
    • Copernicus Climate Service: C3S
    • Copernicus Land Service: CLMS

Core Services

The Data and Information Access Services (DIAS) WEkEO service for marine and climate domains. The DIAS platforms are built to facilitate and standardise access to data.  Funded by European Commission, the DIAS are five cloud-based platforms providing centralised access to Copernicus data and information, as well as to processing tools.  All DIAS platforms provide access to Copernicus Sentinel data, as well as to the information products from Copernicus’ six operational services, together with cloud-based tools (open source and/or on a pay-per-use basis).

COPERNICUS is progressing with the development of its DIAS whereby CMEMS (led by Mercator Ocean International) and ECMWF work together in the DIAS-WEkEO service for marine and climate domains. WEkEO will offer discovery and access services for Sentinel data and forecast & data products from CMEMS and ECMWF, and also cloud computing facilities for analysing satellite images. Thanks to a single access point for the entire Copernicus data and information, DIAS allows the users to develop and host their own applications in the cloud, while removing the need to download bulky files from several access points and process them locally.
