Abstract 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.
