The profiles of aerosol extinction, backscatter coeffcient, and lidar ratio in the lower troposphere over Wuhan are measured by a multi-channel Raman/Mie lidar. Using the lidar ratio retrieved by Raman scattering principle, the profiles of aerosol extinction and backscatter coefficients are also retrieved by Mie scattering signals, without a prior assumption about their relation in the traditional pure Mie signals data analyses. The observations by both Raman and Mie are in good agreement with each other. The high coherence shows that the system is reliable, and the Mie and Raman channels are in good adjustment and have the same field of view.
