MESSy is …
a software framework that combines components, which are numerical representations of our Earth system. Examples of components are atmosphere, land and ocean models, and more.
The unique feature of MESSy is a modular structure that facilitates continuous development and flexible model configurations. The concept has been established by a consortium of institutions with leading expertise in Earth System Modelling and the framework is continually further developed.
MESSy is supported by the German Climate Computing Center (DKRZ), Leibnitz Rechenzentrum (LRZ), the Max Planck Computing and Data Facility (MPCDF), the Jülich Supercomputing Centre (JSC), and the terrabyte cooperation between DLR and LRZ.

New Highlight paper by Ploeger et al. in Atmospheric Chemistry and Physics
The authors present a novel mechanism of how regional anomalies in water vapour concentrations in the upper troposphere and lower stratosphere impact regional atmospheric circulation systems. These impacts include a displaced upper-level Asian monsoon circulation and strengthened prevailing westerlies in the Pacific region. Current climate models have biases in simulating these regional water vapour anomalies…
