High-resolution (1 km) Köppen-Geiger maps for 1901–2099 based on constrained CMIP6 projections

High-resolution maps of the Köppen-Geiger climate classification for historical and future climate conditions (Beck et al., 2023).<b>IMPORTANT: Most users only need the "koppen_geiger_tif.zip" archive (125 MB). It includes GeoTIFFs of Köppen-Geiger maps in varying resolutions for multiple periods and future socio-economic scenarios.</b><br><br>For example, the file "2071_2099\ssp585\koppen_geiger_0p00833333.tif" in the archive provides the Köppen-Geiger map for the period 2071–2099 under the SSP5-8.5 scenario with a resolution of 0.00833333° (approximately 1 km). GeoTIFF files are easily viewed using Geographic Information System (GIS) software such as QGIS.<br><br>The "koppen_geiger_tif.zip" archive also contains a legend file, "legend.txt", which links the numeric values in the maps to the Köppen-Geiger climate symbols and provides the color scheme used for displaying the maps.<br><br>The other archives contain underlying climate data in different resolutions. For details on these archives, please refer to the 'Data Records' section in Beck et al. (2023).<br><br>Please cite Beck et al. (2023) when using the maps in any publication:<br><br>Beck, H. E., T.
