At the Earth’s surface, aerosols, ozone and other reactive gases such as nitrogen dioxide determine the quality of the air around us, affecting human health and life expectancy, the health of ecosystems and the fabric of the built environment.
Dust, sand, smoke and volcanic aerosols affect the safe operation of transport systems and the availability of power from solar generation, the formation of clouds and rainfall, and the remote sensing by satellite of land, ocean and atmosphere.
To address these environmental concerns there is a need for data and processed information. The Copernicus Atmosphere Monitoring Service (CAMS) has been developed to meet these needs, aiming at supporting policymakers, business and citizens with enhanced atmospheric environmental information.
CAMS is operated by ECMWF on behalf on the European Commission. Within CAMS, the CAMS 43 project, led by HYGEOS, aims at improving the global aerosol forecasts provided by ECMWF. To achieve this, CAMS 43 develops, implements and evaluates new parameterizations of aerosol processes in ECMWF’s Integrated Forecasting System (IFS). More information on recent developments carried out by CAMS43 are available in this paper.
