EVALUATION AND COMPARISONOFAIRPOLLUTIONDISPERSIONMODELS AERMOD DURING PRE-MONSOON

Abstract

 Accurate representation of air pollutant dispersion is essential for environmental management and planning purposes. In the present study, two state-of-art air pollution dispersion models, namely AERMOD and ISCST-3 are implemented during the pre-monsoon period of 2010 at Ranchi. AERMOD model is equipped with comprehensive atmospheric boundary layer processes and the other model is based on Gaussian Plume Dispersion concepts only. The purpose of the study is to understand the dispersion of air pollutants such as SO2 , NOX and PM10 at Ranchi and additionally the model inter-comparison. The AERMOD model derived boundary layer parameters are validated with the available micro-meteorological tower based insite measurements and upper air measurements at Ranchi during 1-7 April 2010.
