Characteristics of Spatial Distribution of Precusor Gases in the Plume of Power Plants by Aircraft Measurement
Abstract
Emissions of particles, volatile organic compounds, and nitrogen oxides have increased after the economic expansion was formed by construction of power plants and industrial complex in the past. Primary and secondary pollutants are enriched in plumes from power plant. Emissions from power plants have a strong influence on transport, distribution of pollutants and an effect of human health in the troposphere. Air pollutant emission of power plant are necessary for the management and strategies of appropriate pollution decline. However, it was included uncertainties of unknown significance. Aircraft measurements can be used as a tool to analyze to power plant emissions and to check the accuracy of emission inventories. This study was planned to chemical characteristics and spatial distribution of precusor gases that was emitted by power plants from aircraft measurement. And it was measured for the purpose of monitoring the long-range transport and background concentration over the Yellow sea. In this study, aircraft measurements were carried out over the west side of South Korea in a month (2019.05.15 - 2019.06.08). This measurement was centered on the West Coast power plants (such Taean, Boryeong and Dangjin) and industrial complex (such Daesan Petrochemical complex and Hyundai steel complex) in Korea. Some instruments were installed in Beechcraft 1900D from Hanseo university for precursor gas monitors (CO, O3, NO2 and NH3) and the chemical ionization mass spectrometry (HNO3 and SO2). This research was supported by the National Institute of Environmental Research (NIER) and National Strategic Project-Fine Particle of the National Research Foundation of Korea (NRF) funded by the Ministry of Science and ICT (MSIT), the Ministry of Environment (ME), and the Ministry of Health and Welfare (MOHW) (2017M3D8A1092015), Korea.
