Marine pollution data acquisition method and system

Abstract

The invention discloses a marine pollution data acquisition method, which comprises the following steps: detecting the ozone concentration of a target marine area through ozone foundation observation, determining a to-be-selected point set according to the ozone concentration, obtaining an aerosol to-be-detected area according to the to-be-selected point set, and detecting the aerosol concentration of the aerosol to-be-detected area through satellite remote sensing. And treating the aerosol concentration to obtain a pollution threat area, and giving out early warning according to the pollution threat area. According to the method, aerosol data is obtained by combining the ozone sensor on the ground and satellite remote sensing, a potential pollution area is obtained and pollution prediction is realized through ozone pollution and aerosol comprehensive detection, and compared with traditional single pollutant detection and ozone concentration and aerosol obtained through satellite remote sensing, the method has the advantages that the detection accuracy is high; the comprehensive application of foundation detection ozone and satellite remote sensing aerosol detection can better reflect the pollution condition of the region, reduce the interference between ozone and aerosol detection, and make the monitoring region more flexible.

Description

technical field [0001] The invention relates to the technical fields of data processing, marine pollution monitoring and control, and in particular to a method and system for collecting marine pollution data. Background technique [0002] Atmospheric aerosol is a system composed of atmospheric medium and solid or liquid particles mixed in it. Although the content is very small, it has an impact on many physical and chemical phenomena occurring in the atmosphere. For example, the absorption and scattering of solar radiation by aerosol will change the solar radiation albedo of the atmospheric system, thereby affecting the energy balance of the earth-atmosphere system. [0003] There is a certain relationship between ozone and pollutants such as nitrogen oxides, sulfur oxides, and volatile organic compounds in aerosols. They not only have the relationship of competing precursors, but also restrict each other by changing the chemical reaction conditions. The specific relationsh...

Problems solved by technology

The specific relationship is that the oxidative properties of ozone can promote the generation of aerosol particles. Aerosol particles can reduce the concentration of ozone by changing the reflection intensity of solar radiation and inhibiting photochemical reactions. However, there is still a gap in the comprehensive monitoring of ozone and aerosol particles.
