Windcube V2 measurements during Meteor cruise M207

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. For the first part of the campaign, until early February 2024, the lidar was set up to measure at 12 levels up to 200m height. After that the maximum measurement height was adjusted to 290m.The reported Carrier-to-Noise (CNR) level is used to control the quality the measurement, typically leading to a lower data availability at the top heights.
