Abstract

We present new global maps of the Köppen-Geiger climate classification at an unprecedented 1-km resolution for the present-day (1980-2016) and for projected future conditions (2071-2100) under climate change. The present-day map is derived from an ensemble of four high-resolution, topographically-corrected climatic maps. The future map is derived from an ensemble of 32 climate model projections (scenario RCP8.5), by superimposing the projected climate change anomaly on the baseline high-resolution climatic maps. For both time periods we calculate confidence levels from the ensemble spread, providing valuable indications of the reliability of the classifications. The new maps exhibit a higher classification accuracy and substantially more detail than previous maps, particularly in regions with sharp spatial or elevation gradients. We anticipate the new maps will be useful for numerous applications, including species and vegetation distribution modeling. The new maps including the associated confidence maps are freely available via www.gloh2o.org/koppen.

Part (a) present-day results from our study (1980–2016); (b) confidence levels associated with our present-day map; and (c) forest cover map (2000). Historic Köppen-Geiger classification maps for the three previous studies are provided as: (d) Kottek et al. (1951–2000); (e) Peel et al. (1916–1992); and (f) Kriticos et al. (1960–1990). Our future Köppen-Geiger map (2071–2100) is presented in (g) and the corresponding confidence map in (h). The representative period of each map is listed in parentheses. Thin black lines are country borders and the unmapped white area is part of the Mediterranean Sea.
