MESSy – Modular Earth Submodel System

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), and the Jülich Supercomputing Centre (JSC).

  • New publication in Atmospheric Chemistry and Physics

    The new publication by Flora Kluge et al. on “Airborne glyoxal measurements in the marine and continental atmosphere: comparison with TROPOMI observations and EMAC simulations” is now available in its final version in the EGU open access journal “Atmospheric Chemistry and Physics”. In this study measurements of glyoxal (C2H2O2) in the troposphere are compared to collocated glyoxal measurements of the TROPOspheric Monitoring Instrument (TROPOMI) and simulations from EMAC.

  • Recent publication in Atomspheric Chemistry and Physics

    The research article “The effect of ash, water vapor, and heterogeneous chemistry on the evolution of a Pinatubo-size volcanic cloud” by Mohamed Abdelkader et al. has been published in the EGU journal “Atmospheric Chemistry and Physics” as open access. The authors conducted ensemble studies with the ECHAM5/MESSy2 atmospheric chemistry general circulation model (EMAC) on the 1991 Pinatubo volcanic cloud. The experiments include different injection configurations to test the evolution of SO2, SO₄²⁻, ash masses, stratospheric aerosol optical depth, surface area density, and the stratospheric temperature response against available observations.

  • New evaluation paper including EMAC

    The publication “Evaluation of native Earth system model output with ESMValTool v2.6.0” by M. Schlund et al. is now available at EGU’s open access journal “Geoscientific Model Development”. The authors apply the latest version of the ESMValTool to evaluate output of different Earth system models including EMAC. They present a new extension to the ESMValTool, which allows reading and processing native output of these Earth system models, performing a CMOR-like reformatting of output from the different numerical models during runtime.

  • New publication on the evaluation of EMAC

    A new study of D. Dienhart et al. has been published in the open access journal “Atmospheric Chemistry and Physics”. In the publication “Formaldehyde and hydroperoxide distribution around the Arabian Peninsula – evaluation of EMAC model results with ship-based measurements” the authors evaluate EMAC results with ship-borne measurements around the Arabian Peninsula.

  • New publication in Atmospheric Chemistry and Physics

    The new publication by C. Beer et al. “A global climatology of ice-nucleating particles under cirrus conditions derived from model simulations with MADE3 in EMAC” is published in the EGU open access journal “Atmospheric Chemistry and Physics”. C. Beer and colleagues use the EMAC model with the submodel MADE3 to derive a global climatology of ice-nucleating particles under cirrus conditions. The different ice-nucleating particle types are coupled to the microphysical cirrus cloud scheme to consider possible competition mechanisms between these different particle types.
