The dataset contains annual maximum rainfall events at 5 km resolution created using dynamic downscaling of d4PDF 20 km regional experiments. The target event of the dynamical downscaling is set as maximum 72 hours rainfall event between June 1st to November 30th over the catchement area of the Obihiro reference point in Tokachi River. The target domain for downscaling was the area around Hokkaido (some islands were not included). The dynamical downscaling covered three scenarios: historical climate experiment (60 years x 50 ensemble members from 1951 to 2010), +2K future climate experiment (60 years x 9 ensemble members x 6 SST patterns), and +4K future climate experiment (60 years x 15 ensemble members x 6 SST patterns). This dataset contains several thousand years of heavy rainfall at 5km resolution. It is expected to be used for various applications such as statistical evaluation of heavy rainfall, flood risk assessment, and adaptation measures.
