Copernicus Climate Change Service

Copernicus Climate Change Service (C3S) is one of six thematic information services provided by the Copernicus Earth Observation Programme of the European Union. Copernicus is an operational programme building on existing research infrastructures and knowledge available in Europe and elsewhere. C3S relies on climate research carried out within the World Climate Research Programme (WCRP) and responds to user requirements defined by the Global Climate Observing System (GCOS). C3S provides an important resource to the Global Framework for Climate Services (GFCS).

C3S is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Commission. ECMWF is an independent intergovernmental organisation serving its Member and Co-operating States and the broader community. The majority of C3S service elements are implemented by about 260 companies and organisations across Europe, which are selected based on competitive Invitations To Tender (ITTs).

The C3S mission is to support adaptation and mitigation policies of the European Union by providing consistent and authoritative information about climate change. We offer free and open access to climate data and tools based on the best available science. We listen to our users and endeavour to help them meet their goals in dealing with the impacts of climate change.
