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 six CMIP6 GCMs and the shared socioeconomic pathway scenarios SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. The simulations are performed by the following institutions: DWD, KIT, Hereon, GERICS, BTU, C2SM, FZJ, Wegener Centre, and IMGW. The ICON-CLM setup was optimized in the COPAT2 (Coordinated Parameter Testing) initiative of the CLM community by an objective tuning of a large number of model parameters (Geyer et al, 2026, https://doi.org/10.5194/gmd-19-5439-2026).
This simulation was conducted using ICON-CLM-202407-1-2, a version which corrects the aerosol offset. Further details can be found at https://github.com/WCRP-CORDEX/cordex-cmip6-cv/issues/361 and https://doi.org/10.5281/zenodo.19812905. Initial and boundary conditions for this simulation were created via a multi-quadric horizontal interpolation.
The SSP1-2.6 scenarios (2015-2100) are forced by several CMIP6 GCM simulations (MPI-ESM1-2-HR, EC-Earth3-Veg, MIROC6, CMCC-CM2-SR5, CNRM-ESM2-1, NorESM2-MM) and provided for Europe. The simulation with EC-Earth3-Veg-Forcing is extended to 2150. The supplementary data complement the ESGF-publication of the EURO-CORDEX ensemble by the CLM-community.
