One year measurements of vertical profiles of wind speed and wind direction from 40 to 500 m at Clausthal, Harz Mountains, Germany@en

A Doppler windLiDAR (WindCube WLS8-8 [1] from the manufacturer Leosphere, France) was installed at Clausthal (51°47'58.48''N 10°21'7.42'′E, 595 m altitude) in the Harz Mountains, Germany, and operated continuously for a period of nearly an entire year (from 29 October 2014 to 26 October 2015). The wind LiDAR provided the vertical profiles of wind speed and wind direction, measured by means of the Doppler Beam Swinging technique. Four lines of sight are sequentially scanned by a 1.54 µm pulsed fiber laser to perform the geometrical computation of the 3D wind vector components. From the raw data, the average horizontal wind speed and wind direction is calculated routinely for intervals of 10 min. The wind LiDAR continuously collected profiles of wind speed and wind direction at 24 altitudes (40 m to 500 m, with a vertical resolution of 20 m). Data gaps are mainly caused by low clouds and fog, which cannot be penetrated by the laser pulses.

法国Leosphere公司生产的WindCube WLS8-8型多普勒风激光雷达（Doppler wind LiDAR）[1]，安装于德国哈茨山脉的克劳斯特塔尔（坐标：51°47′58.48″N，10°21′7.42″E，海拔595米），并连续运行近一整年（2014年10月29日至2015年10月26日）。该风激光雷达借助多普勒波束摆动（Doppler Beam Swinging）技术获取风速与风向的垂直廓线：系统采用1.54μm脉冲光纤激光器，依次扫描四条视线路径，以完成三维风矢量分量的几何解算。从原始数据中，系统会常规计算每10分钟间隔的平均水平风速与风向。该风激光雷达在24个海拔高度（40米至500米，垂直分辨率为20米）持续采集风速与风向廓线。数据缺失主要由激光脉冲无法穿透的低云与雾霭引发。
