本文介绍了一种利用三台扫描多普勒测风激光雷达同步测量空间某一点风矢量三分量时间序列的方法。知道每个激光雷达在地面上的位置和每个激光束的方向可以重建风速矢量的三个分量。激光束必须在空间中的所需点相交，它们的方向必须是非共面的，因此三角关系允许在任何坐标系中重建速度矢量，这种技术已经在Cabauw的大气研究实验场（塞萨尔）在荷兰进行的测量活动中进行了测试，并与安装在气象桅杆上的声波风速计的测量结果进行了比较。两种测量技术的空间分辨率相差一个数量级。因此，为了正确地比较结果，伪空间滤波器，模仿衰减indu…
AbstractThis paper presents a technique to measure the time series of the three components of the wind vector at a point in space from synchronous measurements of three scanning Doppler wind lidars. Knowing the position of each lidar on the ground and the orientation of each laser beam allows for reconstructing the three components of the wind velocity vector. The laser beams must intersect at the desired point in space and their directions must be noncoplanar, so that trigonometric relationships allow the reconstruction of the velocity vector in any coordinate system.This technique has been tested during a measurement campaign carried out at Cabauw’s Experimental Site for Atmospheric Research (CESAR) in the Netherlands and compared against measurements from sonic anemometers installed in a meteorological mast. The spatial resolutions of both measurement techniques differ by one order of magnitude. Therefore, in order to properly compare the results, a pseudospatial filter that mimics the attenuation indu...
