Atmospheric visibility measurement and rapid inversion of cloud parameters are of great significance for aviation safety during take-off and landing. Traditional visibility data products mainly focus on horizontal observations and cannot provide vertical profile data. Doppler lidar, by detecting the Doppler frequency shift of the atmosphere, can invert wind speed, and its backscattered signal can also be used to invert atmospheric visibility or calculate cloud base height. The detection range and minimum resolution of Doppler lidar meet the requirements of the International Aviation Organization for reporting airport atmospheric visibility and cloud base height, addressing the limitations of existing point-based visibility monitoring systems.
