Land-atmosphere coupling with ICON and CLM5.0 in TSMP

Abstract:

The next generation atmospheric model ICON (https://code.mpimet.mpg.de/projects/iconpublic), and the land surface model eCLM (https://github.com/HPSCTerrSys/eCLM) are incorporated as new component models into the Terrestrial Systems Modeling Platform framework (TSMP, https://www.terrsysmp.org). eCLM is a novel fork of CLM5.0 with a simplified infrastructure that allows for a more straightforward stand-alone use and model coupling. In this talk I will present the impact of coupling approaches between the land and atmosphere on model states, and outline the development strategy along with technical and performance aspects arising from the coupling process.
