The data include daily, monthly, and seasonal variables of CORDEX experiments scaled down onto a ca. 50 km grid over Europe (acronym: EUR-44) based on the ALARO-0 regional climate model. Each file contains a single variable and is formatted according to the CORDEX data protocol - meaning NetCDF-4 compressed, CF-1.4 compliant, with attributes and filenames according to the specified DRS. The experiments provided are evaluation, historical, rcp85, rcp45 and rcp26 using forcing data derived from the CMIP5 model CNRM-CM5. The data are provided on the model computational (native) grid.
