Abstract—This paper gives an overview of the sensitivity of The modeling temporal scales were set to ‘daily’ and
AERMOD paring the simulated concentrations of SO2 ‘monthly’, at which AERMOD has been verified performing
under different model options with the corresponding observed well in our previous study [12]. The discrete receptors located
concentrations. While the influence of meteorological conditions at three TCEQ (mission on Environmental Quality)
on the performance of AERMOD is noticeable, the urban/rural air quality monitoring sites were set in order to evaluate the
dispersion coefficients and the terrain conditions have only a
limited influence on the results from AERMOD. This study performance of AERMOD under different model options and
suggests that AERMOD can use another consecutive year’s consequently to assess the model’s sensitivity. Table 1 lists out
meteorological data as a substitute for a given year if the extreme t
