Abstract: Atmospheric visibility detection lidar technology makes use of scattering characteristics by interaction of laser and atmospheric particles to obtain the extinction coefficient and calculate the meteorological visibility. This kind of technology is widely applied in the atmospheric research and meteorological observation, but has not yet used in the current civil aviation airport. This paper describes the visibility lidar which designed and developed for the civil aviation airport. A series of observation and tests for 6 months have been launched, comparing with the observation results of the light transmissometer, atmospheric forward scattering meter and artificial observations that used at the airport currently. The test results show that this type of DSL-V backward scattering visibility lidar can meet the technical requirements of ISO/FDIS. The detection range is 2 km. The detection error is less than 11.3% (≤26 m) when MOR is 0-600 m, less than 8.2% when MOR is 600-1500 m, less than 14% when MOR is 1500-10000 m.
