The most frequently used climate classification map is that of Wladimir Köppen.. A huge number of climate studies and subsequent publications adopted this or a former release of the Köppen-Geiger map. While the climate classification concept has been widely applied to a broad range of topics in climate and climate change research as well as in physical geography, hydrology, agriculture, biology and educational aspects, a well-documented update of the world climate classification map is still missing. Based on recent data sets from the Climatic Research Unit (CRU) of the University of East Anglia and the Global Precipitation Climatology Centre (GPCC) at the German Weather Service. we present here a new digital Köppen-Geiger world map on climate classification for the second half of the 20th century.
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.
