Abstract
The formation, transport and evolution process of air pollution have obvious temporal and spatial correlation. Various on-line monitoring technologies based on optical detection and spectral retrieval play an irreplaceable role in air pollution monitoring with high sensitivity, high resolution, high selectivity, multi-component and real-time etc. advantages. The new development of monitoring technologies for air quality, emission sources, traffic emission and regional air pollution in China are introduced. By studying the interaction of light and environmental material, the database of the spectral characteristic and the spectrum quantitative analysis algorithm have been developed. Combined with the engineering technology, air pollution monitoring systems have been developed on DOAS, TDLAS, LIF, LIDAR techniques. Application demonstrations have been carried out in many Chinese Cities, e.g. Beijing, Shanghai, Guangzhou, Nanjing etc. And the requirements and suggestions about further research of atmospheric monitoring technologies are proposed.
