MESSy Consortium

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 a global and a limited area model 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.

The Consortium Steering Group (CSG)

Every member institution of the MESSy Consortium has to determine a Consortium Responsible (CR) who will become member of the Consortium Steering Group (CSG). The CSG receives all personal applications, containing a detailled Letter of Intent and related licensing proves of third party software. In case of possible conflicts between two or more Consortium Members due to the Letter of Intent the CSG can ask for an agreement between the Consortium Members.

Organisational structure of the three bodies established for the coordination of activities concerning MESSy. The MESSy Consortium is the group of institutions (Consortium Members), which signed the MESSy Memorandum of Understanding. Every institution determines a Consortium Responsible who will become member of the Consortium Steering Group, the group of Consortium Responsibles. The MESSy Community is the group of end-user Licensees at all Consortium Members.
