Before starting an airfield improvement project or changing the numbers, types, or activity of aircraft at an airfield, an air quality assessment is usually required. This assessment is usually made with an emissions/dispersion model. Two emissions/dispersion models were developed in the early 1970s for use at airports and airbases. The United States Air Force (USAF) developed the Air Quality Assessment Model (AQAM) (Rote, et al., 1975), and the Federal Aviation Administration (FAA) developed the Airport Vicinity Air Pollution model (AVAP) (Wang, et al., 1973). However, these models are obsolete--they are expensive to operate, tedious to enter data into, and since they were not approved by the Environmental Protection Agency, had to be sold for each application. Both the FAA and the USAF noticed that microcomputer advances of the 1980s' could significantly improve airfield modeling. They also noticed that the FAA's and the USAF's modeling requirements were quite similar. It was therefore concluded that the FAA and the USAF should join forces to develop a single modeling system that both agencies could use. This single modeling system is called the Emissions and Dispersion Modeling System (EDMS). EDMS is a refined model designed for use on a microcomputer. It employs special table lookup and numerical integration procedures to permit a microcomputer to perform the tasks that had previously been done on a mainframe computer.
