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.
