Bias corrected climate scenarios over Japan based on NHRCM02 using monthly CDFDM

This dataset is a bias-corrected climate scenario with a grid-spacing of 1-km over Japan based on dynamical downscaling product with the grid interval of 2km NHRCM02. NHRCM02 was calculated in the framework of SOUSEI program (Murata et al. 2017). The observed sea surface temperature (SST) was given to the historical experiment (SPA) and four SST pattern were derived from the CMIP5 experiments and given to the future experiment (SFA) with the emission scenario of RCP8.5. Dataset cover the 20-year periods 1981-2000 for SPA and 2077-2096 for SFA, respectively. The bias correction method CDFDM, a nonparametric method developed by Iizumi et al. (2010; 2011; 2012; 2014; 2017), was modified for monthly application in this study. We used Agro-Meteorological Grid Square Data (Ohno et al. 2016) as the reference data of bias correction. Daily data are currently available for 8 variables (daily minimum, maximum, and average temperature, precipitation, total solar radiation, downward longwave radiation, wind speed, and relative humidity).
