Category:Köppen-Geiger maps for 1901–2099 based on constrained CMIP6 projections

Köppen-Geiger climate classification maps at 1-km resolution (version 2)

This category includes all Köppen-Geiger climate classification maps at 1-km resolution for the past (1901–2020) and future (2041–2099) climate derived from the data in Beck et al. (2023).^[1]

The historical maps (1901–1930, 1931–1960, 1961–1990, and 1991–2020) are based on high-resolution observation-based climatologies. The future maps (2041–2070 and 2071–2099) are based on downscaled and bias-corrected climate projections for seven shared socio-economic pathways (SSPs). A subset of 42 CMIP6 climate projection models was selected based on plausible CO2-induced warming rates from an initial evaluation of 67 models, enhancing accuracy and reducing uncertainties.

The global maps are available here, while the sections below organize the maps per geographic region, period, and climate types.

The original maps at 1-km resolution can be downloaded for free at http://www.gloh2o.org/koppen/. The maps can also be visualized using this interactive web interface.
