The MESSy Consortium aims at integrating the by now distributed knowledge and methodologies of the earth system science and climate research communities into a joint Earth System Model of flexible complexity. This Modular Earth Submodel System (MESSy) combines different global and limited area models two-way nested into the global model coupled to an ocean model, different algorithmic approaches and various alternative process formulations. By this, the MESSy Consortium builds up a comprehensive but consistent chemistry-climate model system enabling numerical modelling of different atmospheric processes over different scales and considering all atmospheric layers from the troposphere up to the thermosphere.
The consortium was founded 1. August 2013 by seven institutions in an understanding to scientifically use and further develop the MESSy infrastructure. The model system and its components developed within the MESSy Consortium are made available and shared within the scientific community. Furthermore, the MESSy Consortium coordinates the developments in the multiple institutions and keeps track, that the MESSy software and the Earth System Model developed remains controllable and documented.
Every institution that wishes to use the Earth System Model for its research purposes and accepts the Memorandum of Understanding (MoU) without restrictions can become an institutional member of the MESSy Consortium. This membership is effected by means of an informal application to the Consortium Steering Group (CSG) and has to be confirmed by the CSG.
