Windcube V2 measurements during Meteor cruise M208@en

The WindCube 2.0 vertical profiling lidar was placed on the ship to measure horizontal wind speed and direction profiles from 40m to about 300m. This pulsed Doppler lidar was continually measuring in DBS (Doppler-Beam-Swinging) mode, where 4 lines of sight measured each cardinal direction at a 28° angle to obtain the horizontal wind components, and a 5th line of sight measuring the vertical wind speed. The recordings of the lidar device are combined with those of a motion measurement setup, comprising an Inertial Measurement Unit (IMU) and a satellite compass that provide motion data in all six degrees of freedom. Motion data are applied to obtain the corrected wind profile data both on a 1-sec and 10-min level. […]
