Copernicus Climate Change Service and Copernicus Atmosphere Monitoring Service (C3S/CAMS)

The Copernicus Climate Change Service (C3S) and the Copernicus Atmosphere Monitoring Service (CAMS) are operated by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Commission.  ECMWF also contributes to the Copernicus Emergency Management Service (CEMS).

C3S provides authoritative information about the past, present and future climate, as well as tools to enable climate change mitigation and adaptation strategies by policy makers and businesses in Europe and the rest of the world. C3S users include scientists, consultants, planners and policy makers, the media and the public. 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).

CAMS provides consistent and quality-controlled information related to air pollution and health, solar energy, greenhouse gases and climate forcing, in Europe and the rest of the world.

At the core of both operational service is an easy to access data infrastructure, the Climate Data Store (CDS) for climate-related data and the Atmosphere Data Store (ADS) for atmospheric monitoring data. The data stores come with all the essential aspects to derive actionable information and to empower data specialists, including documentation and quality assessments as well as a Toolbox for the CDS.
