With the increasingly complexity of pollution, the traditional point equipment or a single lidar instrument can not meet monitoring requirements. It’s significant to build a 3D monitoring network from near-ground to medium and high altitude for a lager-scale comprehensive detection of atmospheric environment, by collaboratively operating multiple lidar systems from multiple monitoring stations. A good knowledge of aerosol evolution law and pollution transmission path, provides data basis for early warning of urban pollution and for government’s decision-making.
