The need for an Earth System model is recognized by various ECMWF Member States (MS). A consortium with representatives from 11 MS is formed in which the seasonal forecast system of ECMWF (system 3) is developed into an earth system model. The project, which is named EC-EARTH, has as general objective to develop a global Earth System model consisting of a state-of-the-art atmospheric general circulation model, a state-of-the-art ocean general circulation model, a sea-ice model, a land model, and an atmospheric chemistry model.
