Abstract: The Terrestrial Systems Modeling Platform (TSMP, https://www.terrsysmp.org) is a scale-consistent, highly modular, physics-based, massively parallel, and fully integrated groundwater-vegetation-atmosphere modeling framework for regional climate system modeling. TSMP is composed of the atmospheric models ICON or COSMO, the land surface model Community Land Model (CLM), and the ParFlow subsurface-surface hydrological model, coupled using OASIS3-MCT. TSMP is applied across a wide range of spatio-temporal scales, ranging from field to continental scale in a variety of applied research topics, such as water resources, land-atmosphere coupling and climate change projections. In a recent development, we have incorporated the next generation atmospheric model ICON (https://code.mpimet.mpg.de/projects/iconpublic), and the land surface model eCLM (https://github.com/HPSCTerrSys/eCLM) as new component models into the TSMP framework. eCLM is a novel fork of CLM5.0 with a simplified infrastructure that allows for a more straightforward stand-alone use and model coupling. We present the impact of coupling approaches between the land and atmosphere on model states, and outline our development strategy along with technical and performance aspects arising from the coupling process using OASIS3-MCT.
