Global 1‑km climate classification maps


We present new glob­al maps of the Köp­pen-Geiger cli­mate clas­si­fi­ca­tion at a high 1‑km res­o­lu­tion for his­tor­i­cal and future cli­mate con­di­tions (1901–2099).
The his­tor­i­cal maps (encom­pass­ing 1901–1930, 1931–1960, 1961–1990, and 1991–2020) are based on high-res­o­lu­tion, obser­va­tion-based cli­ma­tolo­gies. The future maps (encom­pass­ing 2041–2070 and 2071–2099) are based on down­scaled and bias-cor­rect­ed cli­mate pro­jec­tions from the Cou­pled Mod­el Inter­com­par­i­son Project phase 6 (CMIP6) and cov­er sev­en Shared Socio-eco­nom­ic Path­ways (SSPs). We eval­u­at­ed 67 cli­mate mod­els and select­ed 42 with the most plau­si­ble CO2-induced warm­ing rates to derive the future maps. 


The lat­est ver­sion (V2) of the maps can be down­loaded here. IMPORTANT: This archive includes Geo­T­IFFs of Köp­pen-Geiger maps in vary­ing res­o­lu­tions for mul­ti­ple peri­ods and future socio-eco­nom­ic sce­nar­ios. For exam­ple, the file “2071_2099\ssp585\koppen_geiger_0p01.tif” in the archive pro­vides the Köp­pen-Geiger map for the peri­od 2071–2099 under the SSP5‑8.5 sce­nario with a res­o­lu­tion of 0.01° (rough­ly 1 km). The archive also includes a leg­end file, legend.txt, which links the numer­ic val­ues in the maps to the Köp­pen-Geiger cli­mate sym­bols and pro­vides the col­or scheme for dis­play­ing the maps.
