Earth System Models have included the effects of nitrogen and phosphorus on the land carbon budget and land biogeophysics in CMIP5 and CMIP6, respectively. Yet large uncertainties in the impact of these cycles on future trends prevail. To address this uncertainty, we developed a new configuration of the land surface model ICON-Land by coupling the description of land physical processes from JSBACH4 to a new representation of biosphere dynamics, including coupled carbon-nitrogen-phosphorus cycling (QUINCY). Here, we showcase first results from this new land configuration (with interactive carbon-cycle only) coupled to the ICON-XPP Earth system model in concentration- and emission-driven settings and provide the preliminary analyze of the resulting climate-carbon interactions.
