AERMOD : Model Formulation and Evaluation
نویسنده
چکیده
AERMOD is an advanced plume model that incorporates updated treatments of the boundary layer theory, understanding of turbulence and dispersion, and includes handling of terrain 1 On assignment to the National Exposure Research Laboratory, U.S. Environmental Protection Agency. interactions. This paper includes an overview of AERM:OD's features relative to ISCST3, a dispersion model that is widely used for many applications. AERM:OD has been evaluated on 10 databases, which include flat and hilly terrain areas, urban and rural sites, and a mixture of tracer experiments as wei! as routine monitoring networks with a limited number of fixed monitoring sites. This paper presents a summary of the evaluation results of AERM:OD with these diverse databases.

Performance evaluation of CALPUFF and AERMOD dispersion models for air quality assessment of an industrial complex
Air quality model (AQM) is an essential tool for management of air quality in near field region of an industrial complex. Model validation study using site specific input data can boost the consistency on accuracy of model’s performance for air quality management. This study describes the validation of CALPUFF and AERMOD for assessment of NOx concentrations in near field region of a steel indus...
متن کاملDispersion model evaluation of PM 2 . 5 , NOX and SO 2 from point and major line sources in Nova Scotia , Canada using AERMOD Gaussian plume air dispersion model
AERMOD was used to model the air dispersion of point and major line emissions of PM2.5 in Halifax and Pictou, NOX in Halifax and SO2 in Halifax, Sydney and Port Hawkesbury, Nova Scotia, Canada. Emission inventory data for 2004 were used in simulations within four, 50 km x 50 km, domains over annual, monthly and 1–hour averaging periods. Annual averaged surface concentration maps are reported...
متن کاملPerformance of AERMOD at different time scales
As high-density monitoring networks observing pollutant concentrations are costly to establish and maintain, researchers often employ various models to estimate concentrations of air pollutants. The AMS/EPA Regulatory Model (AERMOD) is a fairly recent and promising model for estimating concentrations of air pollutants, but the effectiveness of this model at different time scales remains to be v...
