Abstract
In this study, the relationship between sulphur oxides (SOx) emissions and sulfur dioxide (SO2) concentration was intensively analyzed using a simple Eulerian box model based on hourly data by district in Korea. There was little difference in the conversion rate of local SOx emission to the concentration of SO2 in all districts. However, sensitivity of SOx emission to the calculated concentration of SO2 was different significantly district by district. SOx emission was the most contributable factor in Ulsan, Chungnam, Busan, and Incheon, but the reaction term was more contributable factor in many other districts. For example, in districts where emission is the most sensitive factor additional emission management is required for managing the concentration of SO2. And it was found that differences between the monitored and the estimated SO2 concentrations in Korea was the smallest in summer and the largest in winter. There is a possibility that the difference in seasonal external effects had an effect on these seasonal differences. © 2022. All Rights Reserved.
