摘要：	The impetus for this project is a limitation with modeling capabilities to comprehensively understand and explain airport contributions to local air quality. Although the FAA's Emissions and Dispersion Modeling System (EDMS) represents the state-of-the-art in emissions and dispersion (through USEPA's AERMOD) modeling capabilities, there are still limitations related to the handling of reactive pollutants and the formation of secondary pollutants. Therefore, the goal of this project was to develop guidance for combining measurements with modeling to fully support airport air quality assessments. The scope of the project involved conducting various reviews and demonstrations of measurements and modeling through case studies. The resulting assessments involved the use of measured data and various modeling exercises, including sensitivity-type analyses, trend assessments, and modeled-versus-measured comparisons. Although these assessments were extensive in their coverage of various modeling parameters, they did not include formal validation or uncertainty assessments, which were considered outside the scope of this project. The purpose in conducting the assessments was to assess the measurement and modeling techniques for their application to quantifying airport contributions to local air quality. The review work involved examining all applicable emissions and dispersion models, but mainly focusing on EPA- and FAA-recommended models, as well as somealternatives. In addition to EDMS and AERMOD, others, such as CAL3QHC and CALPUFF, were considered for their potential to either replace or augment the current capabilities in those recommended models. The model selections involving EDMS and CMAQ were largely based on being able to model chemical transformations and to leverage the FAAs previous research in this area. For the field measurements, the equipment was selected based on practical applications at airports (i.e., weighing various issues such as cost of equipment, expertise necessary, fidelity of data, and quantity of data). All equipment/techniques used were USEPA reference, equivalent, or other approved methods.
