Evaluation of the Large EURO?CORDEX Regional Climate Model Ensemble

The use of regional climate model (RCM)-based projections for providing information in a research and service contexts is currently expanding very fast. This has been possible thanks to considerable effort developing comprehensive ensembles RCM projections, especially Europe, the EURO-CORDEX community (Jacob et al., 2014, 2020). As end 2019, developed set 55 historical scenario (RCP8.5) using 8 driving global models (GCMs) 11 RCMs. article presents ensemble including its design. We target analysis better characterize quality RCMs by an evaluation these simulations over number classical variables extreme impact-oriented indices period 1981–2010. For main variables, generally agree with observations reanalyses. However, several systematic biases are found as well, shared responsibilities among GCMs: Simulations overall too cold, wet, windy compared available or Some show strong on temperature, others precipitation dynamical but none models/simulations can be defined best worst all criteria. aims at supporting proper within services context.
