Tóm tắt

The WindCube v2 is a pulsed LIDAR and uses four beams sent in succession in the four cardinal directions along a 28�scanning cone angle to measure horizontal velocity and wind direction. A fifth beam is sent in the vertical direction to measure vertical velocity. Measurement heights are user-programmed and range from 40 m to 200 m. During HilFlowS, the WindCube v2 was programmed to measure from 40 m to 150 m at 10-m intervals. The data sampling rate was 1 s, wind speed accuracy was 0.1 m/s, and direction accuracy was 1.5� for the instrument. The data were averaged across 10-min. averaging intervals.
