Modeling of Pollutant Dispersion from a Moving Source

Application to Airport Pollution

Abstract

The atmospheric dispersion process of pollutants emitted from a moving aircraft is represented by a puff diffusion model to simulate its movements precisely near the airport, under the assumption of a Gaussian distribution function. Three-dimensional diffusion parameters are estimated by matching calculated concentrations to those measured in the field with tracer experiments. By using these parameters, the time-dependent ground level concentrations of CO and NOx and the isopleths of NOx for quasi-static takeoff operations of aircraft are presented.
