Abstract: Using the AMS/EPA Regulatory Model (AERMOD) and information on the emission inventory and relevant parameters of pollutant sources in Huludao city during 2016,the surface SO2 and NO2 concentrations were simulated and the results were validated with the observational data from four atmospheric environmental monitoring stations in Huludao.The results show that the simulated mean concentrations of SO2 or NO2 are slightly smaller than observational values,and the major one among various reasons is that the emission inventory in the model is not perfect.The correlation between the simulated and observational concentrations of SO2 is relatively better than that of NO 2,with the mean value of correlation coefficient of 0.71 for SO2 and 0.64 for NO2.The relative er-ror of the simulated concentration of SO 2 averaged at four monitoring stations is -19.4% and that of NO2 is -25.6%.The correlation between the simulated and observational SO 2 in winter and spring is better than other sea-sons,with the correlation efficient of 0.79 in winter.While the correlation between the simulated and observational NO 2 in winter and autumn is better,with the correlation efficient of 0.69 in winter.
