摘　　要：介绍了一台用于平流层中上部温度探测的双波长激光雷达 ,分析了数据处理方法及其过程。该激光雷达获得的结果与NOAA NMC及MSISE 90模式资料对比表明 ,在 30～ 40km高度范围内三者反映了较一致的温度分布特征。一般情况下 30～ 40km范围内它们的温度偏差小于 3K ;低层 30km以下很可能主要受气溶胶的影响 ,相对偏差小于 6K。A Rayleigh scattering lidar is presented for temperature observation in the mid and upper stratosphere, both principle and process of data analysis are described. Temperature profiles obtained by lidar show the coincident distribution with the NOAA/NMC and MSISE-90 model over the altitudes of 30 to 40 km. Generally, temperature biases between lidar and NOAA/NMC or MSISE-90 model are less than 3 K from 30 km to 40 km altitude, not larger than 6 K at the lower altitudes probably due to the influences of aerosol.
