Micropulse lidar (MPL) is an effective tool for aerosol detection. To verify the accuracy of detection, MPL was used to calculate the aerosol optical depth (AOD) in the northern suburb of Nanjing with the Fernald inversion method. The inversion results were compared with those obtained with a sun-photometer,a Raman-Rayleigh-Mie lidar and a standard aerosol detection instrument (a moderate-resolution imaging spectroradiometer). The results show good correlation among them. The MPL is useful for AOD inversion and can be used to verify other measurement data effectively.
