Abstract:. The performance of a high resolution tristatic minisodar is evaluated over an area of complex topography using a 30m high meteorological mast equipped with cup anemometers and bivanes. The instrumentation was in operation at the Moni Toplou Wind Park (Island of Crete, Greece) and the comparison covered a range of high wind speed and different meteorological conditions during day and night-time periods. The Sodar measurements of mean wind speed and direction for 15 min time segments agreed with the in situ measurements although an underestimation of the wind speed is evident. On the other hand the standard deviations of the wind speed and direction as estimated by Sodar gave poor agreement with the in situ instrumentation.
