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).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.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.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.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).Please cite Beck et al. (2023) when using the maps in any publication:Beck, H. E., T. R. McVicar, N.
