The Copernicus Atmosphere Monitoring Service (CAMS) provides consistent and quality-controlled information related to air pollution and health, solar energy, greenhouse gases and climate forcing, everywhere in the world. CAMS is one of six services that form Copernicus, the European Union's Earth observation programme which looks at our planet and its environment for the ultimate benefit of all European citizens. 

CAMS consolidates many years of preparatory research and development that was funded by the European Union through a series of MACC projects. MACC brought together partner organisations from across Europe with expertise in areas such as environmental monitoring and forecasting, operational forecasting services, and research on atmospheric composition.

CAMS is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the European Commission. ECMWF is an independent intergovernmental organisation supported by 34 states. It is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its member states. To provide and further develop the CAMS portfolio, ECMWF works with many service providers around Europe. By doing so, CAMS combines the expertise and infrastructure that exist in Europe to provide a range of services that are unequalled by any other organisation in the world.
