This dataset is bias corrected climate scenarios over Japan with the spatial resolution 1km using CMIP6. Five GCMs were selected from CMIP6; MIROC6, MRI-ESM2-0, ACCESS-CM2, IPSL-CM6A-LR, MPI-ESM1-2-HR. Regarding the GHGs emission pathways, SSP1-RCP2.6, SSP2-RCP4.5, and SSP5-RCP8.5 were used. CDFDM proposed by Iizumi et al. (2010; 2011; 2012; 2014; 2017) was modified so that the model is constructed within each month. Daily data for eight variables (daily mean, max, min temperature, precipitation, global solar radiation, downward longwave radiation, wind speed, and relative humidity) are avairable from 1900 to 2100. The abbreviations of the variables in the download page are tas [degree C], tasmax [degree C], tasmin [degree C], pr [mm/day], rsds [MJ/m2/day], rlds [MJ/m2/day], sfcwind [m/s], and rhs [%], respectively.

Bias correction using modified CDFDM method was applied to the 5 selected GCMs from CMIP6. The CDF for the calibration period was conducted in each month. Daily observational data from 1980 to 2018 were utilized to maximize the reference period. Historical data for the GCM was composed of 1980-2014 from the historical run and 2015-2018 from the SSP585 run for each GCM. As a reference data, we used the Agro-Meteorological Grid Square Data (Ohno et al. 2016). Data formats were based on the Gregorian calendar. Linear trend was preserved for the daily mean, max, and minimum temperature and downward longwave radiation.
