Netherlands - Wind 10 to 200 metres above the North Sea - KNMI

The KNW (KNMI North Sea Wind) atlas is based on the ERA-Interim reanalyses dataset which captures more than 39 years (1979- 3 months ago) of meteorological measurements and generates 3D wind (temperature, etc) fields consistent with these measurements and the laws of physics.

This dataset is downscaled using the state-of-the-art weather forecasting model, HARMONIE with a horizontal grid of 2.5 km. The result is a high resolution dataset of 35 years: the KNW dataset. state-of-the-art weather forecasting model, HARMONIE with a horizontal grid of 2.5 km. The vertical profile of wind speed was calibrated against the 200 m tall Cabauw measurement mast to obtain a single wind shear correction coefficient which was applied throughout the whole dataset. The result is a high resolution dataset of more than 39 years: the KNW dataset.
