In order to ensure the accuracy of the radar observation data, the first calibration experiment of networked aerosol light detection and ranging (LiDAR) was carried out by Meteorological Observation Center of China Meteorological Administration in september 2017. By adopting the method of single radar’s photoelectric system calibration and multi-radar comparison observation calibration based on statistical analysis strategies, the 532nm scattering channel shared by the networked experiment radars was checked and calibrated. After calibration, the relative standard deviation of backscattering coefficient in 532nm channel was reduced from 90.8% to 20.4% in height range of 1km~2km, and from 244.3% to 35.9% in height range of 2km~5km. And the data quality has been greatly improved. In the aerosol lidar calibration experiment, the radar backscattering coefficient difference was significantly reduced, and the consistency of data observation was greatly improved.This work will provide good hardware quality control assurance for aerosol lidar networking applications.
