Copernicus Climate Change Service

The Copernicus Climate Change Service (C3S) responds to environmental and societal challenges associated with human-induced climate changes.


The service will give access to information for monitoring and predicting climate change and will, therefore, help to support adaptation and mitigation. It benefits from a sustained network of in situ and satellite-based observations, re-analysis of the Earth climate and modelling scenarios, based on a variety of climate projections.


The service will provide access to several climate indicators (e.g. temperature increase, sea level rise, ice sheet melting, warming up of the ocean) and climate indices (e.g. based on records of temperature, precipitation, drought event) for both the identified climate drivers and the expected climate impacts.


The Copernicus Climate Change service is under implementation.


In November 2014, the European Commission signed a Delegation Agreement with ECMWF (European Centre for Medium-Range Weather Forecasts) for the implementation of the service. The public version of the Technical Annex of this agreement is available in the Document Repository (under Technical Documents) available on this website.


The first stage of implementation is dedicated to the so called "proof of concept", meaning capacity building and testing of the overall architecture. The operational capacity will be reached during the third year of operations and it will be preceded by a pre-operational stage.

The service will be based on four pillars:


  • A climate data store;
  • A sectoral information system providing tailored information to the end users;
  • An evaluation and quality control of the information;
  • Outreach and dissemination activities.


For a more detailed presentation of the Copernicus Climate Change Service, please refer to the attached factsheet and the service website, where you will find the Beta version of the service.



The evolution of the Copernicus Climate Change service will be supported at best by the outcomes of a series of projects launched under the 2013 FP7 Space Call related to climate modelling and observation analyses. Furthermore, a specific expert group had been set-up to assess the need and opportunity for an independent European space-borne CO2 observation capacity (download the Expert Group Report).
