EC-Earth

EC-Earth is a global climate model system which is based on the idea to use the world-leading weather forecast model of ECMWF (European Centre of Medium Range Weather Forecast) in its seasonal prediction configuration as the base of the EC-Earth climate model. The model system can be used in several configurations including the classical climate model (atmosphere, soil, ocean, sea ice) and Earth System configurations (adding atmospheric chemistry and aerosols, ocean bio-geo-chemistry, dynamic vegetation and a Greenland ice sheet).

History

Around 2006, the need for an ESM was recognized by various ECMWF Member States. This effectively initiated the development of EC-Earth.
