Description This is a historical reconstruction dataset of hourly expected wind generation based on dynamically downscaled atmospheric reanalysis for assessing the spatio-temporal impact of on-shore wind in Japan. The dataset consists of a set of netCDF files with yearly archives of reconstruction results from 1958 to 2012; hourly expected on-shore wind power potential in Japan with a spatial resolution of approximately 5 km mesh has been reconstructed from the numerical weather model reanalysis results. The expected per-unit output values at each location were calibrated using a nonparametric machine learning model that learns statistical relationships between spatial/meteorological features of target locations and actual wind farm outputs. A convenient way to handle this dataset would be to use a tool for manipulating netCDF files, such as CDO: Climate Data Operators. Version history Ver. 1.0: Released. Ver. 1.1: The preprocessing of the source information used for dataset preparation has changed.

The reanalysis data used to generate this reconstruction dataset were provided by the Japan Meteorological Agency.
