Abstract

The invention discloses an integrated space and terrestrial information based stereoscopic monitoring method for air pollution and a monitoring system. The method comprises the following steps: establishing satellite remote sensing and atmospheric model monitoring to monitor the distribution and diffusion trends of large-scale dyes in a region to initially determine local and external sources; establishing a laser radar network monitoring system to locate and track air pollution sources at the same time; and establishing a densely distributed ground monitoring grid site for accurate analysis of the causes of atmospheric pollution sources. Through the three-level monitoring system, the detection of air pollution in the monitoring area can be completed, and serious areas of air pollution, sources of pollutants, and the distribution and diffusion situation of key pollution sources can be clarified. And then the processing, statistics, and analysis of massive data can be completed based ona software platform to obtain monitoring results. The invention can realize effective monitoring of atmospheric pollutants, which has high distance resolution and time resolution.

Description

technical field [0001] The invention relates to the technical field of air pollution environment monitoring, in particular to a space-ground integrated three-dimensional air pollution monitoring method and monitoring system. Background technique [0002] With the acceleration of industrialization and urbanization, my country's environmental problems have become increasingly prominent, and smog problems of varying degrees have appeared across the country. Air pollution has seriously restricted social development and the ecological environment. [0003] In this situation, environmental monitoring for air pollution is particularly important. Atmospheric environmental monitoring is the measurement process of observing and analyzing the concentration of pollutants in the atmospheric environment and its impact on the environment, so as to clarify the types and concentrations of pollutants in the atmosphere, and observe their temporal and spatial distribution and change rules. Mo...
