A method and system for collecting marine pollution data

Abstract

The invention discloses a method for collecting marine pollution data, which comprises the steps of detecting the ozone concentration of a target ocean area through ozone ground-based observation, determining a set of points to be selected according to the concentration of ozone, obtaining an area of ​​aerosol to be inspected according to the set of points to be selected, and using satellite remote sensing Detect the aerosol concentration in the area where the aerosol is to be inspected, process the aerosol concentration, obtain the pollution threat area, and issue an early warning according to the pollution threat area. The invention combines the ground ozone sensor and satellite remote sensing to obtain aerosol data, obtains the potential area of ​​pollution and realizes pollution prediction through the comprehensive detection of ozone pollution and aerosol, compared with the traditional single pollutant detection and the ozone concentration and atmospheric The comprehensive application of sol, ground-based ozone detection and satellite remote sensing aerosol detection can better reflect the pollution situation in the region, reduce the interference between ozone and aerosol detection, and make the monitoring area 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.
