超大城市综合气象观测试验之测风激光雷达数据评估

为评估用于超大城市综合气象观测试验的测风激光雷达，从最大有效探测高度和数据获取率两方面对测风激光雷达的探测能力进行分析，同时使用测风激光雷达与深圳气象梯度观测塔的测风资料从不同观测高度、不同观测值等方面进行对比分析，结果表明：测风激光雷达与深圳气象梯度观测塔的风速、风向一致性较好，相关系数分别为0.96、0.99，平均绝对误差分别为0.54 m/s、9.95°，且不同高度层的测风结果也较为一致，但雨天和雾天条件对测风激光雷达的最大有效探测高度和数据获取率影响较大，设备探测能力受到一定的限制。

EVALUATION OF WIND LIDAR DATA INMEGACITIES EXPERIMENT ON INTEGRATED METEOROLOGICAL OBSERVATION

To evaluate the wind lidar used inmegacities experiment on integrated meteorological observation, the present study analyzes the detection capacity of the wind lidar by assessing the maximum effective detection height and the data acquisition rate. The wind data from wind lidar and Shenzhen meteorological gradient tower is compared at different heights and in different measurement ranges. The results show that the wind speed and direction detected by wind lidar are quite consistent with those observed by the meteorological gradient tower. The wind speed and direction correlation coefficients are 0.96 and 0.99, and the average absolute errors are 0.54 m/s and 9.95°. The results of wind lidar and meteorological gradient tower at different altitudes are consistent with each other. Nonetheless,rainy and foggy weather conditions have significant impact on the maximum effective detection height and data acquisition rate of wind lidar, so the detection capacity of wind lidaris relatively restricted.
