Concurrent mean wind speed (November 27, 2017)

    Asked by WOZ_RVO.nl 1514 days ago Answers (1)

    The concurrent mean wind speed (i.e. when measurements for both locations HKZA and HKZB are valid) differ by 0.1 m/s. Is there any explanation, given the small distance between the 2 positions?

        The dataset used for the combined wind resource assessment from the two LiDAR buoys includes recorded concurrent wind speeds over a 12-month period (05/06/2016 to 04/06/2017). The mean wind speeds recorded at 100 m over that period differ by 0.1 m/s in the raw data. However, the difference is primarily due to differences in the data availability for each LiDAR buoy. The HKZA buoy has a lower availability than HKZB. After quality control, and considering only time steps with concurrent measurements of both buoys, the mean wind speeds at 100 m differ by only 0.01 m/s. This level of accuracy is well within measurement uncertainties. Please find additional information in the memo (see attachment).
