Wind - model statistics for 1979-2013 at 10-200 meters above the North Sea - KNW End user pack of maps and time series

The KNW (KNMI North Sea Wind) atlas is based on the ERA-Interim reanalyses dataset which captures more than 40 years (January 1979 - August 2019) 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 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 40 years: the KNW dataset. The model statistics in this specific dataset cover the original 35 year period of the KNW Atlas.

Quantitative result

Value: complete (all days between 1979-01-01 and 2013-12-31)

Statement: Every 6 hours the ERA-Interim Re-analysis initializes the HARMONIE Weather Model cycle 37h1.1 throughout the whole of the model domain. The atlas is comprised of the successive 1-6 hour HARMONIE forecasts after each 6 hourly cold start.
