Wind Profile

Multi-level wind resource analysis from ERA5 pressure levels.

Returns annual/monthly mean wind speeds, Weibull distribution parameters (k, c), estimated capacity factor, and P50/P90 statistics at each requested hub height (default: 10, 50, 80, 100, 120, 150 m).

Hub heights are interpolated from ERA5 pressure-level wind fields (1000–700 hPa ≈ 110–3000 m ASL) using log-linear vertical interpolation. More accurate than surface log-law extrapolation for heights > 40 m.
