dc.description.abstract本研究以反軌跡為基礎,考慮多個地域區塊在軌跡線上,因工廠污染物排放量與氣象因子的交互作用下,對受體點的貢獻濃度所造成的影響。模式以忠明測站為例子,做1997年整年的模擬研究,模擬結果PM10相關係數為0.47,SO2相關係數為0.18,NOx相關係數為0.41,結果也顯示,在1至2月及10至12月模擬結果較其它月份來的好。由於本研究尚未考慮工廠煙囪高度的問題,僅將其視為地面污染源,所以當模擬的軌跡線遇到重大污染源時,模擬濃度容易產生陡升的現象。另外,模式中也計算硫酸鹽及硝酸鹽的濃度,經與實驗值分析,硫酸鹽相關係數可達0.44以上,硝酸鹽在0.71以上。zh_TW
dc.description.abstractTrajectories are often used to describe the long-range transport of air pollutants in the atmosphere. NCHU trajectory model with the base of backward trajectory scheme and Tsuang and Chao's circuit model coupled meteorology and pollutant emission data is applied to simulate the pollutant concentration of receptor grid. Chung-Ming air quality monitoring station, located at the center of Taichuang city, is chosen as the receptor point. The simulation is conducted for whole year in 1997 and compare with the observed data. Each trajectory is traced 24hr back in time. The correction coefficient(R) for PM10, SO2, and NOx are 0.47, 0.18, and 0.41, respectively. We find the simulation in winter is better than else. When the trajectory across large emission source, extremely high concentration will appear, for the point sources are supposed to emit from surface instead of stack height. Furthermore, sulfate and nitrate are simulated in this model. The concentration coefficient of sulfate is above 0.44 and nitrate is above 0.71.en_US
