The Service will consolidate many years of preparatory research and development that was funded by the European Union in the form of the series of MACC projects. MACC brought together partner organisations from across Europe with expertise in areas such as environmetal monitoring and forecasting, operational forecasting services, and research of atmospheric composition. CAMS delivers the following operational services:

-Daily production of near-real-time analyses and forecasts of global atmospheric composition

-Reanalyses providing consistent multi-annual global datasets of atmospheric composition with a frozen model/assimilation system

-Daily production of near-real-time European air quality analyses and forecasts with a multi-model ensemble system

-Reanalyses providing consistent annual datasets of European air quality with a frozen model/assimilation system, supporting in particular policy applications

-Products to support policy users, adding value to “raw” data products in order to deliver information products in a form adapted to policy applications and policy-relevant work

-Solar and UV radiation products supporting the planning, monitoring, and efficiency improvements of solar energy production and providing quantitative information on UV irradiance for downstream applications related to health and ecosystems

-Greenhouse gas surface flux inversions for CO2, CH4 and N2O, allowing the monitoring of the evolution in time of these fluxes

-Climate forcings from aerosols and long-lived (CO2, CH4) and shorter-lived (stratospheric and tropospheric ozone) agents Anthropogenic emissions for the global and European domains and global emissions from wildfires and biomass burning
