摘要
介绍了瑞利激光雷达的基本结构,描述了使用瑞利散射激光雷达探测平流层和中间层低部大气温度的数据处理方法,构建同时包含标准大气模式温度信息和实际探测背景噪声的模拟数据,对此模拟数据进行背景扣除、平滑去噪、参考点选取等计算分析,探讨提高温度反演精度的实用算法。并应用此数据处理方法对瑞利激光雷达的实际测量数据进行了计算处理,将计算结果与模式CIRA86、HALOE卫星数据进行对比分析,反演高度30～45km时误差1～3K,45～65km误差大约在2～5K,65～70km误差＜10K。
The configuration of Rayleigh lidar is introduced.The method of retrieved temperature in strato- sphere and lower mesosphere by Rayleigh scattering lidar is presented.Simulations were performed which included climatological profile taken from atmospheric model and realistic atmospheric disturbances.For opti- mizing temperature retrieved arithmetic,the several operations were taken such as the method of abstracting background,smoothing signal and choosing a proper reference point and so on.Comparisons betwee...
