1 km global Köppen–Geiger climate classification for present and future

CHELSA 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).

Comparison of Köppen Geiger climate classification (kg1) for 1981-2010 with projections for 2071-2100 based on the MPI-ESM1-2-HR model run with an ssp585.

We provide 6 different definitions of Köppen-Geiger climate classifications for each timestep.
