摘　　要：文章从四川气象综合观测业务需求出发,研究激光雷达在大气探测领域的应用,系统地分析了激光雷达实测气溶胶对传统差分吸收激光雷达(DIAL)方法和三波长双重差分吸收激光雷达(Dual-DIAL)方法测量大气臭氧的探测误差;讨论了激光雷达实测气溶胶的含量与空间分布对探测误差的影响,结果表明气溶胶含量主要影响消光项造成的误差,气溶胶空间分布则对后向散射误差产生影响。This paper studies the application of lidar in the field of atmospheric detection based on the needs of comprehensive meteorological observation in Sichuan.The detection errors of aerosol measured by Lidar for atmospheric ozone measurement by conventional differential absorption lidar(DIAL) and three-wavelength differential absorption lidar(Dual-DIAL) are analyzed systematically.The influence of aerosol content measured by radar and spatial distribution on detection error is also discussed.The calculation results show that the aerosol content mainly affects the error caused by the extinction term, and the spatial distribution of aerosol affects the backscattering error.
