North Korea is one of the unknown places regarding to climatic change and variability. The unknown climatic knowledge is mainly due to less availability of temporally and spatially continuous climate data. In order to overcome the current limitation in climate study for North Korea, we utilize the reanalysis climate datasets from Asia (JPL-55), Europe (ERA5), and U.S. (NCEP-DOE) for temperatures and precipitation. To select the best reanalysis data for North Korea among the three datasets, we validate the reanalysis with the available twenty-seven weather station data in North Korea obtained from WMO Global Telecommunication System (GTS) for 1982-2015. Using the selected reanalysis dataset, the spatial patterns of temperatures and precipitation in North Korea are examined and the temporal changes are quantified with spatio-temporal regression analysis over the last thirty-four years. A potential association of climate and vegetation changes in North Korea is suggested. This study will contribute to unveil the climatic variation in North Korea, which is one of major factors for ongoing North Korean famine. Additionally, the results in this study will build the bridge to the marginalized community of geography in North Korea.
