The overview of aerosol mass concentration and spatial distribution in the air pollution plume on the large point source by aircraft measurement in Korea
Abstract
The air quality of Korea is affected by various sources such as local emissions and long-range transport. A major source of aerosol is point sources and mobile sources in the Seoul Metropolitan Area (SMA). And many thermal power plants to serve energy to SMA are concentrated in the western part of the Korean peninsula. In addition, due to the petrochemical complex and steel complex that are concentrated around thermal power plants and large ports, pollutants may inflow the SMA by westerly winds. Although air pollutants emitted from large point sources are continuously monitored by "clean-sys", but it is hard to observe the diffusion and pathways of the emitted pollutants. To identification of the diffusion and pathways of the air pollutants can be used as important data to air quality model and air quality forecast.
We are conducting aircraft measurement to identify air pollutant emission characteristics of large point sources located in the western part of the Korean peninsula during spring and fall of 2019. And the HR-ToF-AMS, PTR-ToF-AMS, CIMS, gas monitors (NO2, CO, O3, NH3) were installed to Beechcraft 1900D for aircraft measurement. The scientific goal of this study is to characterize aerosol mass concentration and spatial distribution of the air pollution plume on the point sources. The results of aerosol measurements from large point sources will be presented in concentration of chemical composition (OA, SO42-, NO3-, NH4+) and size distribution of particle. The results of this study can be provided as important data to improve air quality model and air quality forecasting.
