Data Dutch Offshore Wind Atlas

The Dutch Offshore Wind Atlas (DOWA) is a wind atlas covering a period of 10 years, from 2008 until and including 2017.

Regional numerical weather model HARMONIE and additional satellite and aircraft measurements were used to downscale global re-analysis ERA5 to dataset of hourly information on a 2.5 by 2.5 km grid spacing and up to 600 m height. The DOWA domain covers 789 by 789 points centered around Cabauw and contains at least wind speed and wind direction at 17 height levels: 10, 20, 40, 60, 80, 100, 120, 140, 150, 160, 180, 200, 220, 250, 300, 500 and 600m.

The DOWA dataset contains daily 3D files and 10 year time series. The data used to be stored in KNMI Data Centre (KDC) and a DOWA download manual was provided, but now the data is stored on the KNMI Data Platform (the manual is no longer useful).
