CHELSA V.2.1 includes a 1km global Köppen-Geiger climate classification for the time periods 1981-2010. It is based on the newest bias corrected CMIP6 scenarios and is available for four different timesteps until 2100 (2011-2040, 2041-2070, and 2070-2100), and three shared socioeconomic pathways (ssp126, ssp370, ssp585).
