摘要: 利用美国第三代空气质量模式系统Models-3对2002年1月17~18日辽宁中部城市群大气污染物SO2,NO2和PM10的浓度分布进行了数值模拟,并将模拟结果与监测结果进行了对比分析。结果表明:污染物的模拟值与观测值变化趋势具有一致性,模式反映了SO2,NO2和PM10浓度的时空分布特征和变化规律,再现了污染物浓度呈波峰波谷日变化的重要特征,可用于辽宁中部城市群区域大气污染物的研究。

Abstract: The distributions of SO_2,NO_2 and PM_(10) in the middle multi-cities of Liaoning were simulated by the Third-Generation Air Quality Modeling System on Jan.17~18,2002.The results showed that the change tendencies of the simulated values were consistent with those of the observed data,which indicated that the model could be used for evaluating and predicting the concentrations of SO_2,NO_2 and PM_(10) in the middle multi-cites of Liaoning.
