Wind Integration National Dataset (WIND) Toolkit

Wind resource data for North America was produced using the [Weather Research and Forecasting Model (WRF)](https://www.mmm.ucar.edu/weather-research-and-forecasting-model). The WRF model was initialized with the European Centre for Medium Range Weather Forecasts Interim Reanalysis (ERA-Interm) data set with an initial grid spacing of 54 km. Three internal nested domains were used to refine the spatial resolution to 18, 6, and finally 2 km. The WRF model was run for years 2007 to 2014. While outputs were extracted from WRF at 5 minute time-steps, due to storage limitations instantaneous hourly time-step are provided for all variables while full 5 min resolution data is provided for wind speed and wind direction only.

The following variables were extracted from the WRF model data:
- Wind Speed at 10, 40, 60, 80, 100, 120, 140, 160, 200 m
- Wind Direction at 10, 40, 60, 80, 100, 120, 140, 160, 200 m
- Temperature at 2, 10, 40, 60, 80, 100, 120, 140, 160, 200 m
- Pressure at 0, 100, 200 m
- Surface Precipitation Rate
- Surface Relative Humidity
- Inverse Monin Obukhov Length
