In this paper an attempt has been made to undertake performance evaluation of the two well-known regulatory models, AERMOD (07026) and ADMS-Urban (2.2) for a tropical city such as Delhi. The model is applied to estimate ambient air concentrations of SO2 and NO2 for the years 2000 and 2004 over seven sites in Delhi. Both model evaluation and inter-comparison is performed.
