Carrier-to-Noise-Threshold Filtering on Offshore Wind Lidar Measurements

Presentation given at a Webinar about lidar data filtering as part of the IEA Task 32 working group on lidars. The presentation discusses the effect of data filtering on the observed wind climate for an offshore site in the North Sea. It is found that filtering with a CNR threshold can significantly influence the measured wind speed distribution. The effect is found for both short and long-range wind lidars. Therefore, care should be taken when filtering the data of wind lidars.
