7. DATASET OVERVIEW
7.1 Abstract
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 thearea 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 suchas statistical evaluation of heavy rainfall, �ood risk assessment, and adaptation measures.
