Abstract

ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. Aircraft sources are treated explicitly as accelerating jets. Application of the model to air quality calculations was conducted for the Model Inter-Comparison (MIC) Study of Project for the Sustainable Development of Heathrow (PSDH). ADMS-Airport was compared with monitored air quality data and four other modelling approaches, including semi-empirical methods, the Lagrangian model LASPORT and FAA model EDMS. Further studies of ADMS-Airport using a revised emission inventory are also presented.
