ABSTRACT:   The AERMOD air dispersion modeling system was applied to predict the dispersion of nitrogen dioxide (NO2) in Maptaphut industrial area, Thailand. In this paper, data from 292 point sources were used as input data. Modeled results were validated with measured data, obtained from 10 receptor sites on an hourly basis. The Tier 1 approach (100% conversion of NOx to NO2) resulted to the highest predictions of NO
