High Sensitivity Spectroscopic Techniques for Atmospheric Environment Monitoring

The high sensitivity spectroscopic technique for atmospheric monitoring is an interdisciplinary subject developed by environmental science and optics. It based on the interaction between light and environment and was used to solve environmental problems. The high sensitivity spectroscopic technique can monitor the temporal and spatial distribution of pollutants, and the evolution of pollutants. It has become one of the main development directions of environmental monitoring technology due to its characteristics of multi component, non contact, no sampling, high sensitivity, large range and rapid monitoring. Facing the complex environmental pollution problem in the chemical park, the spectroscopic techniques can acquire the concentration distribution of various pollutants in a highly sensitive and non contact manner, and it can master the pollution status of the chemical park and effectively provide the support for the air pollution control of the chemical park. Facing the problem of atmospheric heavy pollution in Beijing Tianjin Hebei and Yangtze River Delta regions, the spectroscopic techniques can be used to obtain the formation process, transformation process and formation mechanism of heavy pollution by ground based observation network and on board/airborne platform observation. The wide applications of high sensitivity spectroscopic techniques have shown that spectroscopic techniques are very useful tools for comprehensive environmental management, e.g. chemical parks and regional air pollution.
