When the laser emitted by the visibility lidar passes through the atmosphere, various gas molecules and particles in the atmosphere will absorb and scatter the laser, thereby changing the energy, spectral characteristics, polarization state and other information of the backscattered light. By receiving and analyzing the optical properties of the backscattered light, the corresponding properties of gas molecules, aerosol particles and various atmospheric parameters can be inversely deduced.

The X-band phased array weather radar is used to monitor the occurrence, development, intensity and position of weather targets within a 120km radius around the station in real time. It promptly acquires distance, azimuth, reflectivity, radial velocity and dual-polarization information as well as inversion products of cloud, rain and other weather targets relative to the radar, enabling automatic identification, tracking and analysis of weather targets, and achieving high-spatial-resolution and fine-scale d
