D-1 Appendix D EDMS Model ing of Airside Operat ions D.1 . In t roduct ion EDMSD1,D2 is a combined emissions and dispersion model for assessing air quality at airports.

D-2 • CO2 (carbon dioxide) for aircraft only, • CO (carbon monoxide)

D-3 through input dialogs for all aircraft or for each study aircraft. Within EDMS, a study aircraft refers to a specific group of aircraft operations performed by a single aircraft-engine combination.

D-4 EDMS can calculate hourly emissions, and generate AERMOD input files for the following pollutants: • CO (carbon monoxide) , • THC (total hydrocarbons)
|
From page 127... ...
D-5 An emissions inventory must first be generated before dispersion can be performed, since the set of emissions that are dispersed is the same as that produced from the annual inventory. More details on algorithms implemented in EDMS can be found in Reference D2.
