Figure 1: Percentage difference in Dunkelflaute events (lasting at least 2 or more consecutive days) between C3S and ECEM datasets derived from EURO-CORDEX regional climate models (original GCMs: CNRM, EC-Earth, MPI, and IPSL). The percentage difference is calculated as (GCM - Reference Reanalysis Data), where ERA5 is the reference for C3S, and ERA-Interim is the reference for ECEM.
