2011年3月21日至4月19日，中国气象局气象探测中心利用车载多普勒测风激光雷达在北京观象台进行实验，对大气边界层进行观测，并利用激光雷达距离平方校正信号梯度法进行了大气边界层高度的反演与分析。激光雷达观测数据处理结果表明，测量期间当地时间上午800和下午800的平均混合层高度或近地面稳定边界层高度分别为(1.44±0.75) km和(2.23±1.13) km，平均边界层高度分别为(2.88±0.92) km和(3.37±0.82)km。对比同步探空气球数据，激光雷达反演结果与由位温梯度、相对湿度梯度获取的平均混合层高度和边界层高度相比，相关系数达94%，体现出较好的一致性。

From Mar. 21 to Apr. 19 in 2011, atmospheric observations with mobile Doppler wind lidar at Beijing observatory are operated by China Meteorological Administration. Atmospheric boundary layer is observed and analyzed by the gradient of lidar range-corrected signal. The processed results of lidar observation data indicate that the average mixing layer or surface stable boundary layer height is (1.44±0.75) km at 800AM and (2.23±1.13) km at 800PM, the average atmospheric boundary layer height is (2.88±0.92) km at 800AM and (3.37±0.82) km at 800PM, respectively. Compared with the gradient of potential temperature and relative humidity of synchronous radiosonde, the correlation index is as much as 94%, which shows good consistency with lidar.
