Using ICON-CLM, the CLM community provides historical RCM simulations and climate projections for the EUR-12 domain of EURO-CORDEX by a dynamical downscaling of different CMIP6 GCMs. In a second step, a quality checked subset of the RCM simulations at 12 km (driven by MPI-ESM1-2-HR, EC-Earth3-Veg, and MIROC6) is determined and, for SSP1-2.6 and SSP3-7.0, further downscaled to 3 km (CEUX-3 domain) using ICON-CLM in a convection-permitting setup. The simulations for CEUX-3 are performed by the following institutions: DWD, KIT, Hereon, GERICS, and BTU. The ICON-CLM setup was optimized in the CECPI-Ger (Coordinated Evaluation of Convection Permitting Climate simulations with ICON-CLM for Germany) initiative of the CLM community by an objective tuning of a large number of model parameters (Geyer et al, 2026).
The SSP1-2.6 simulations (2015-2100) are the 2nd nest of a 2-step nesting ICON-CLM simulation. The first nest runs at 12 km spatial grid spacing over the EUR-12 domain, forced by several CMIP6 GCM simulations (MPI-ESM1-2-HR, EC-Earth3-Veg, MIROC6, CMCC-CM2-SR5, CNRM-ESM2-1, NorESM2-MM). The 2nd nest is at 3 km spatial grid spacing over the CEUX-3 domain, covering hydrological Germany. The supplementary data complement the ESGF-publication of the EURO-CORDEX ensemble by the CLM-community.
