Conically scanning lidars assume the flow to be homogeneous in order to deduce the horizontal wind speed.However, in mountainous or complex terrain this assumption is not valid implying a risk that the lidar will derive an erroneous wind speed.The magnitude of this error is measured by superdry baseball top collocating a meteorological mast and a lidar at two Greek sites, one hilly and one mountainous.The maximum error for the sites investigated is of the order of 10 %.In order to predict the error for various wind directions the flows at both sites are simulated with the linearized flow model, WAsP Engineering 2.
0.The measurement data are compared ice blue graphic tee with the model predictions with good results for the hilly site, but with less success at the mountainous site.This is a deficiency of the flow model, but the methods presented in this paper can be used with any flow model.
