Abstract:The Federal Aviation Administration (FAA) requires the use of the Emissions and
Dispersion Modeling System (EDMS) for air quality analysis involving aviation sources.
Dispersion in EDMS has previously been computed by CALINE3 and PAL2. With the
advent of the Environmental Protection Agency’s (EPA’s) AERMOD dispersion model,
the FAA has made a commitment to replacing the older dispersion models in EDMS with
AERMOD. AERMOD’s dispersion algorithms are state-of-the-art and have been shown
through validation efforts to model the physics of the atmosphere more accurately than
previous algorithms. In addition to accuracy, the robust features in AERMOD allow a
more complete modeling scheme (e.g., such as the use of polygon-area sources and polar
coordinates for receptors). This paper discusses the technical aspects of integrating
AERMOD into EDMS.
