The CAMS Radiation Service is designed to meet the requirements that have been specified for the Copernicus Atmosphere Monitoring Service (CAMS). The precursor projects MACC and MACC-II/-III prepared the CAMS Radiation Service in terms of implementation, sustained operation and availability. It was ensured that the service lines have been designed to best meet both the requirements of downstream service providers and end users at the European, national and local levels, and the requirements of the global scientific user community. This page provides a high level overview of the solar radiation service; more details can be found in the Section Detailed documentation.

For clear-sky conditions, an irradiation time series is provided for any location in the world using information on aerosol, ozone and water vapour from the CAMS global forecasting system

Input quality control, regular quarterly benchmarking against ground stations, and regular monitoring the consistency and detecting possible trends is performed.
