Fig. 4: Measurement campaigns experiment.

The mast locations and elevation maps for the Bolund (A), Askervein (C), and Perdigão (E) campaigns. The tower positions are colored by the average prediction error when using that specific mast as the input to predict the wind. In the Askervein and Perdigão cases some masts did not provide a valid measurement for that experiment. (B, D, F) show the wind directions for the different experiments for each terrain. Source data are provided as a Source Data file.
