A new all-weather outdoor Raman-Mie scattering lidar system was developed and used in the atmospheric aerosol pollution monitoring for the continuous observation of atmospheric boundary layer, tropospheric aerosol and cloud optical characteristics. In lidar system design, this lidar system adopted the existing mature technology of Mie scattering, polarization and Raman lidar remote sensing, and its structure was compact and convenient for transportation. In lidar control design, it was easy to operate with one-touch button and the system was available with manual and automatic working modes as well as network control and data transmission functions. The automatic and manual retrieval software were applied in the lidar data processing. The former can automatically process and display the observed results in real time according to the system settings, while the latter can retrieve and display the accurate observation data according to the parameters set by the user. This lidar system has achieved the requirements of production application and it can be widely used in the fields of atmospheric environment monitoring and atmospheric science.
