Specially adapted to wind energy requirements, new independent remote sensing systems as the Doppler Wind Lidar System (WINDCUBE® v2, Leosphere) are capable of measuring the 3D wind profile with high accuracy (~ 1%) and good data availability up to 240m AGL. The standard approach of Lidar measurements generally assumes a homogeneous horizontal wind field for the individual measuring heights, whereas in complex terrain, wind flow is not homogeneous and the errors increase with terrain complexity. Thanks to the WINDCUBE´S 5th beam and resulting direct measurement of w and flow-inclination the manufacturer developed in 2012 the Online FCR™ Flow Complexity Recognition software tool which will be taken into account in this study.
