Extreme climatic events have increased in frequency and intensity over tha last decades due to global warming. Our study evaluates spatial distribution of changes in climate extreme indices on the Korean Peninsula by downscaled high-resolution data based on an empirical quantile mapping technique and 29 global climate models. Grid‐based observation data with 3.0 km resolution derived from weather stations with data covering 30 years from 1976 to 2005 using a modified PRISM approach were used as reference data for bias-correction. Future projections until 2100 based on two Representative Concentration Pathway (RCP) scenarios of CMIP5 were considered for the variables of daily precipitation, minimum temperature, and maximum temperature. We finally estimated spatial changes in climate extreme indices at 3.0 km resolution. The reproducibility assessment of simple precipitation intensity index (SDII) and annual total precipitation in wet days (PRCPTOT) showed applicability of techniques for downscaling, with the biggest difference of 2.66% and 1.91%, respectively, compared to the observation. The annual maximum 5-day precipitation (Rx5day) and annual maximum value of maximum temperature (TXx) showed highest increase rate under the far future period and RCP8.5 scenario. The derived spatial distribution of climate extreme indices based on a multi‐model ensemble can contribute to vulnerability assessment at a national scale by reducing uncertainties caused by selecting a specific climate model.
