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 demonstrated by the comparison with ozoneresults of SAGE II and HALOE. The analysis indicates that ozone profiles by lidar agreewell with ones by SAGE II over the altitudes 18～37.5km, their relativedifferences were within 12% from 20 to 30km and less than 26.5% from 32 to 35km altitudes.The ozone distribution by Lidar and HALOE measurement coincided well with the relativedifference less than 15% in the range 20～32km. Intercomparisons of ozone profiles presented bylidar, SAGE II and HALOE measurements on the same or adjacent days, show the betteragreement in the stratosphere.
