This is the dataset simulated by high resolution atmospheric global climate model (AGCM) with 60km horizontal resolution, and dynamical downscaling to Japanese region by regional climate model (RCM) with 20km horizontal resolution. The dataset is continuous one from the middle of 20th century to the end of 21th century, consists of the past climate (4 members of initial value ensemble) and the future climate (4 emission scenarios of the RCP2.6/4.5/6.0/8.5).

The continuous high-resolution simulations enable to estimate how meteorological events change from the past to the end of the 21st century, and to estimate when changes due to global warming become more pronounced than natural variability.
