Doppler LIDAR Wind Ranger | PCS.2000-24 + LIDAR Trailer
The Doppler Wind Lidar Wind Ranger product family comprises three different lidar types: two allowing seamless wind profiling of the atmospheric boundary layer (Wind Ranger 200 and Wind Ranger BL) and one for ultra long range wind measurements (Wind Ranger 25k).
The Wind Ranger 200 and Wind Ranger BL are compact, cost-effective and easy-to-use instruments for vertical determination of the 3D wind vector and turbulence quantities. They perform continuous VAD scans of the laser beam at a zenith angle of 10 degrees. The maximum scanner movement is 2 revolutions per second. While the Wind Ranger 200 uses a special FM-CW method for the lower 200 metres measurement height and thus allows measurement heights as low as 7 metres above ground, the Wind Ranger BL uses a pulsed transmission signal and determines the respective measurement heights from the runtime of the received signal.
The Wind Ranger 25k, the next-generation Doppler wind lidar with a robust full-hemisphere scanner, is specifically designed to measure wind fields over distances of more than 25 kilometres.
Details
For mobile wind measurements with high requirements, e.g. in the wind energy sector, trailers are available for stand-alone or grid-connected use, which accommodates both a Doppler SODAR of type PCS.2000-24 and a Doppler LIDAR (Wind Ranger, Streamline). The involved measuring techniques complement each other ideally in terms of data accuracy and data availability: the LIDAR method provides the higher measuring accuracy, while the SODAR method also works in fog, very low-hanging clouds or other severe visibility restrictions.
