MESSy

The Modular Earth Submodel System (MESSy)

MESSy is a software providing a framework for a standardized, bottom-up implementation of Earth System Models (or parts of those) with flexible complexity. "Bottom-up" means, the MESSy software provides an infrastructure with generalized interfaces for the standardized control and interconnection (=coupling) of "low-level ESM components" (dynamic cores, physical parameterizations, chemistry packages, diagnostics etc.), which are called submodels. MESSy is a multi-institutional community project: https://www.messy-interface.org/

The most frequently applied MESSy configurations used to investigate ICE-3’s research themes are:

• The global model ECHAM5/MESSy
• The global-regional modelling system MECO(n)
• The chemical box model CAABA/MECCA
• The atmospheric chemistry MESSy DWARF
