Land surface processes influence the impact of climate on humans and ecosystems. Understanding these processes and feedback becomes even more relevant in the context of the burden we put on land surfaces in mitigating climate change(land use, carbon dioxide sequestration). Earth System Models have been used to study these interactions but typically act on very coarse resolutions, not considering local effects, e.g. surface heterogeneity. Our project aims to resolve this by setting up a Large Eddy Model(LEM) version of the ICON-ESM that can operate at very high resolution(~50 m) and with the same advanced land surface component as the ESM(JSBACH). This will enable a direct comparison between the LEM and ESM modes and give us insights into the significance of resolving surface heterogeneity in model representation. The project is a part of the Land Atmosphere Feedback Initiative (LAFI) project, funded by the DFG, which aims to deepen our understanding of land-atmosphere interactions and quantify them better using synergistic observations and model simulations.
