Velocity azimuth display (VAD) scanning Lidars cannot measure the wind speed accurately in complex terrain because the fundamental assumption that the wind speed is horizontally homogeneous is violated. Leosphere provides an online correction, the Flow Complexity Recognition (FCR), in order to correct the effect of the terrain on the WINDCUBE measurements. The aim of this project was to assess the accuracy of this correction by comparing the corrected Lidar measurements to the uncorrected measurements and to simultaneous measurements taken by cup anemometers on a met mast. The measurements took place in a complex site, Hrgud, in Bosnia and Herzegovina, provided by ERS and where the reference met mast was erected and instrumented by COWI.
