摘　　要：通过与SAGEⅡ和HALOE两个卫星仪器多天的臭氧数据对比，验证了激光雷达观测合肥地区平流层臭氧数据的有效性．分析表明在18～37．5km范围内激光雷达与SAGEⅡ及HALOE观测得到的臭氧浓度分布表现了较好的一致性；其中，激光雷达与SAGEⅡ臭氧结果的相对偏差一般在20～32km范围内小于10％，32～35km范围内小于26.5％；激光雷达与HALOE臭氧结果的相对偏差在21～32km范围内一般小于15％．激光雷达、SAGEⅡ和HALOE三者同天或邻天的平流层臭氧结果相比，也表现了较好的一致性．The validation of stratospheric ozone measurement by lidar was demon strated by the comparison with ozone results of SAGE Ⅱ and HALOE. The analysis indicates that ozone profiles by lidar agree well with ones by SAGE Ⅱ over the al titudes 18~37.5 km, their relative differences were within 12% from 20 to 30 km and less than 26.5% from 32 to 35 km altitudes. The ozone distribution by Li dar and HALOE measurement coincided well with the relative difference less than 15% in the range 20~32 km. Intercomparisons of ozone profiles presented by lidar, SAGE Ⅱ and HALOE measurements on the same or adjacent days, show the better agreement in the stratosphere.
