Pre-operational precursor service of the Copernicus Atmospheric Monitoring Service
Monitoring Atmospheric Composition and Climate - Interim Implementation - was the pre-operational Copernicus Atmosphere Monitoring Service (CAMS). MACC-III provides data records on atmospheric composition for recent years, data for monitoring present conditions and forecasts of the distribution of key constituents for a few days ahead. MACC-II combines state-of-the-art atmospheric modelling with Earth observation data to provide information services covering European air quality, global atmospheric composition, climate forcing, the ozone layer and UV and solar energy, and emissions and surface fluxes.
