Abstract

This paper introduces the structure and working principle of Mie-Rayleigh-Raman lidar, observes and compares the Nanjing aerosol of Mie channel with that of the Raman channel respectively. It shows that there is some uncertainty about lidar boundary parameters, however, Raman scattering lidar could overcome such problems effectively that we often use multi-channel Mie-Rayleigh-Raman lidar. The observation results obtained by groundbased Mie-Rayleigh-Raman lidar are consistent with that from space-based lidar, and the former is more accurate than the latter. Integrated observation of the two will be the main direction of the development of aerosol observation in the future.
