Progress in Three-Dimensional Monitoring Technology of Regional Atmospheric Pollution

The formation, conversion, transmission, and evolution of environmental pollutants involve strong temporal-spatial correlation. Rapid, real-time, and dynamic monitoring technologies capable of evaluating multiple components are key to monitoring the atmospheric pollutants. Based on the principle of spectroscopy, environmental optical monitoring technology has become one of the main directions because of its characteristics of non-contact, non-sampling, high sensitivity and large scale rapid monitoring. These technologies have been widely used in the fields of environment, meteorology and scientific research. To understand the pollution process in the Beijing-Tianjin-Hebei Region in China, an atmospheric environmental monitoring network together with superstation observation platforms have been set up. The integrated use of multi-platform remote sensing technology has both scientific and practical research value. On the one hand, it can obtain the temporal-spatial microphysical characteristic of particles and provide methods and technology to control atmospheric complex pollution. On the other hand, the evaluation of inter-urban/regional air pollution transport offers valuable information and references for air pollution control.
