Robust Köppen-Geiger (KG) Climate Classification Maps

The nc file contains two global Köppen-Geiger (KG) Climate Classification maps (resolution 0.5°).

The robust maps are developed by using monthly temperature and precipitation data from UDEL, CRU, JRA55, NCEP/CFSR, MERRA2, ERA5, and WFDEI gridded products over the period 1980 to 2017.

MasterMap 1 shows the most frequently observed climate types among all KG maps for each grid point, after directly merging the climate maps produced by the seven datasets.
MasterMap 2 results from estimating the medians of precipitation and temperature among the seven datasets at each grid point.
