7. DATASET OVERVIEW
7.1 Abstract
This dataset provides statistically downscaled data, which is high-resolution hydrologicalinformation, that will allow cold, snowy regions Hokkaido, which could be significantly affectedby climate change, to investigate measures for adapting to climate change. MRI-NHRCM20, a climate
model with 20-km spatial resolution, was used for the climate change forecast data.

8. DATA PROCESSING
8.1 Data Processing (1)8.1.1 General Explanation of the data producer's knowledge about thelineage of a dataset
MRI-NHRCM20 was used for climate change prediction data. DSJRA-55, JMA mesh average, and JMA
analytical rainfall were used for bias correction.
