This paper briefly discusses the mobile ground-based incoherent Doppler wind lidar system, with iodine filters as receiving frequency discriminators, developed by the Ocean Remote Sensing Laboratory, Ocean University of Qingdao, China. The presented result of wind profiles in October and November 2000, retrieved from the combined Mie and Rayleigh backscattering, is the first report to our knowledge of wind measurements in the troposphere by such a system, where the required independent measurement of aerosol-scattering ratio can also be performed. A second iodine vapor filter was used to lock the laser to absolute frequency reference for both wind and aerosol-scattering ratio measurements. Intercomparison experiments of the lidar wind profile measurements were performed with pilot balloons. Results showed that the standard deviation of wind speed and wind direction, for the 2-4 km altitude range, were 0.985 m/s and 17.9 degrees, respectively.
本文简要讨论了由中国青岛海洋大学海洋遥感实验室研制的、以碘滤光片作为接收鉴频器的地基移动式非相干多普勒测风激光雷达系统。利用米氏散射和瑞利散射相结合反演得到的2000年10月和11月的风廓线结果，据我们所知，是关于该系统在对流层进行风测量的首次报道，该系统还可进行所需的气溶胶散射比独立测量。使用第二个碘蒸气滤光片将激光锁定到绝对频率参考，以进行风和气溶胶散射比测量。利用探空气球对激光雷达风廓线测量进行了比对实验。结果表明，在2 - 4千米高度范围内，风速和风向的标准偏差分别为0.985米/秒和17.9度。
