摘要：

多普勒测风激光雷达能够实现高时空分辨率的大气风场测量，中国海洋大学成功研制了可以测量风廓线和三维大气风场的车载多普勒测风激光雷达，并已交付中国气象局使用。为了检验该激光雷达的测量性能，2011年春季开展了车载激光雷达与探空气球风廓线同步观测实验，获取了55组比对数据。本文介绍了此次同步观测实验，给出了激光雷达和探空气球风廓线数据的比对个例，并对所有比对数据进行了统计分析。同步比对结果显示，激光雷达与探空气球风廓线数据的风速均方根偏差为2.76 m/s。通过分析比对偏差，证明了激光雷达风廓线测量结果的准确性。

Abstract:

Doppler wind lidar is able to measure atmospheric wind field with high spatial and temporal resolution. A mobile Doppler wind lidar for wind profile and three-dimension wind field measurements was developed by Ocean University of China and then operated by China Meteorological Administration. In order to verify the measurement performance of the lidar, a synchronous observation campaign with the mobile lidar and radiosonde was carried out in the Spring of 2011 and obtained 55 intercomparison measurements. This paper introduces the synchronous observation campaign, shows a case study of wind profile intercomparison by lidar and radiosonde, and statistically analyzes all the intercomparison measurements. The results of the synchronous intercomparison shows that the root mean square deviation of wind speed measured by lidar and radiosonde is 2.76 m/s. By means of analyzing the deviation, the wind profiles measured by lidar are proved to be accurate.

Key words: remote sensing, wind profile, Doppler lidar, wind lidar, synchronous intercomparison
