Abstract:
Differential absorption lidar(DIAL)plays an important role in photochemical stereo-monitoring system. With its advantages of high spatial and temporal resolution profile detection, it develops rapidly and has been widely used in remote sensing detection of ozone concentration in the troposphere. This paper firstly introduced the basic principle of DIAL. Then,the latest research progress of DIAL at home and abroad was summarized which focused on different laser light source technology. Meanwhile, the application of DIAL in environmental monitoring was discussed. Based on the current situation and management requirements of urban ozone pollution in China, the overall framework of ozone lidars monitoring network for operational application was preliminarily explored and designed. Despite of many manufacturers, there is alack of unified technical specifications and industry standards. Data quality and accuracy need to be improved, for poor comparability was observed between the lidar technology and the standard analysis methods. The development trend of the ozone lidar technology were discussed, such as the localization of core components, system miniaturization, automation and commercialization, multi platform and collocation of other monitoring methods.
