The primary role of NIMS/KMA to CMIP6 is coordinated with tasks such as 1) Registration of new KMA’s Advanced Community Earth-system Model (K-ACE, Lee et al. 2019) and 2) experiment for ScenarioMIP using two ESMs (K-ACE, UK Earth System Model(UKESM1)). In this presentation, preliminary results of two ESMs will be presented. The simulation for ScenarioMIP has been performed with four different SSP-RCP scenarios and CMIP6 forcing data form input4MIPs. The warming trend with increment of GHGs is similar to the observation and the trend of Global Mean Surface Temperature (GMST) is within the CMIP5 ensembles range in historical (1850~2014) simulations. Also, the temperature change in 2100 is +2.4K from SSP1-2.6 and +5.4K from SSP5-8.5 scenario simulations. These results are higher than the mean value of CMIP5 ensembles, but it is within the range of CMIP5. The detailed analysis will be shown in this presentation.
