World Map of the Köppen-Geiger climate classification updated
The most frequently used climate classification map is that of Wladimir Köppen, presented in its latest version 1961 by Rudolf Geiger. 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.

This zip-archive contains one text file (ASCII text with CRLF line terminators) including the climate classification on a regular 0.5 degree lat/lon grid for the period 1951 to 2000. The text file contains one line of header followed by 92416 lines of grid box center coordinates (latitude, longitude) with corresponding climate class abbreviated according to the climate classification established by Köppen and Geiger. The data are available on the global land areas.
