A Modeling Study on the Transport of Acid Pollutant by Regional Acid Deposition Model -Spacial Pattern and Variation of Air Pollutants on Eastern Asia and Central Part of Korea-

산성우모델에 의한 산성강하물의 수송에 관한 연구 - 동아시아 및 우리나라 중부지방의 대기오염물질 시공간분포 -

The acid deposition and photochemical modeling study was performed on the Eastern Asia using Regional Acid Deposition Model(RADM). The results of this study show that horizontal distribution of $SO_2$, concentration and dry deposition flux was higher in Beking, Shanghai and central part of Korea. However distribution pattern of sulfate and $O_3$ concentration calculated by RADM were not similar to emission pattern. In daytime, $SO_2$, sulfate and $O_3$ were mixed to whole PBL but in nighttime because of inversion layer these pollutants were suppressed to lower level.
