The article presents an updated digital Köppen-Geiger world map of climate classification for the second half of the 20th century. The map is 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. The authors highlight the importance of an updated map for various research areas, including climate and climate change, physical geography, hydrology, agriculture, biology, and education. The map covers 31 climate classes, with some classes occurring only in very small areas. The resulting map shows more regional details due to its high spatial resolution and provides opportunities for further investigations, such as studies on global climate change. The authors conclude that the updated Köppen-Geiger classification remains relevant and can be applied for another 100 years, with the underlying digital data available for public use.The article presents an updated digital Köppen-Geiger world map of climate classification for the second half of the 20th century.
