Embodiment 1

[0045] Such as figure 1 As shown, the air-ground integrated monitoring and early warning system for coastal atmospheric composite pollution of the present invention comprises the following steps:

[0046] (1) In the coastal and high-altitude mountains with cloudy and foggy, high-humidity ambient gas and particulate matter measurement, the cloudy and foggy atmosphere cannot be effectively separated, interferes with the measurement, and causes instrument failure due to water ingress. Develop a dry sample injection system suitable for gas particulate matter monitoring instruments under high-humidity environmental conditions. Prototype device; through the combination of fluid dynamics simulation calculation and wind tunnel test, the variable diameter size of the shroud is designed to realize the deceleration, pressure reduction, flow stabilization and pressure stabilization of the oncoming airflow during the high-speed flight of the aircraft, so that the gas and particulate matter ...

Abstract

The invention discloses a coastal atmosphere combined pollution sky-ground integrated monitoring early-warning system. The system comprises the following steps of (1) establishing multi-platform gas particle monitoring instrument atmosphere sample feeding system and a low-loss desalting and dehumidifying integrated sampling system under the costal and high-altitude multi-cloud unique environment;(2) developing offshore area atmosphere boundary layer pollutant concentration and three-dimensional meteorological element vertical sounding; (3) performing integrated monitoring on large-load airship, unmanned aerial and onboard atmospheric physical and chemical parameters, and optimizing a test platform; (4) monitoring vehicle-mounted and shipborne high-precision conventional meteorological parameters, physical parameters of cloud, main pollution gas and particles; (5) establishing a multiplatform integrated monitoring command and decision-making platform; and (6) establishing a multiplatform atmospheric monitoring data integration analysis and processing system to obtain the costal atmospheric combined pollution sky-ground integrated monitoring early-warning system. The multiplatform system disclosed by the invention is high in integration degree, and plays a demonstration role in the multi-scale and multiplatform fused sky-ground integrated monitoring technology and test organization.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment monitoring, in particular to a sky-ground integrated monitoring and early warning system for combined coastal air pollution. Background technique [0002] The eastern coastal area is controlled by the East Asian monsoon system. The unique weather and climate conditions, combined with the high concentration of urbanization in this area, the huge consumption of fossil fuels, and the intensive emission of air pollution have led to frequent occurrence of combined air pollution and haze weather, which has aroused concern from the general public and the government. highly valued. Traditional monitoring is limited to ground stations, and regular element observation stations are established in urban areas. There are few super stations for full-component observations, especially the lack of comprehensive observations of the entire urban area, the eastern ocean, and the boundary layer at dif...
