VWL 3D Scanning Doppler Wind LiDAR
VWL
The VWL is a pulse laser atmospheric wind profiler that measures the wind profile by detecting the Doppler frequency shift of laser echoes reflected from the atmosphere. It provides 3D scanning wind measurement without a physical mast. MetSensor UK supplies the VWL as the official UK reseller of Zata IoT.
