MODEL APPLICATION REMARKS REMARKS FORDISTILLERY PLANTSAPPLICATIONSOCD(Offshore andcoastalDispersionModel)FDM(FugitiveDust Model)RTDM(RoughTerrainDiffusionModel)It determines the impactof offshore emissionsfrom point sources onthe air quality of coastalregionsIt incorporates overwaterplume transport anddispersion as well aschanges that occur as theplume crosses the shorelineMost suitable foroverwater sources shoreonshore receptors arebelow the lowest shoreheightSuitable for emissionsfrom fugitive dustsourcesSource may be point,area or line (up to 121source)Require particle sizeclassification max. up to20 sizesComputesconcentrations for 1 hr,3hr, 8hr, 24hr or annualaverage periodsEstimates GLC iscomplex/rough (or flat)terrain in the vicinity ofone or more co-locatedpoint sourcesTransport distance max.up to 15 km to up to 50kmComputes for 1 to 24 hr.or annual ave5rageRequire sources, and metdataRequires source emissiondataRequire hrly met data atoffshore and onshorelocations like water surfacetemperature; overwater airtemperature; relativehumidity etc.Require dust source particlesizesSource coordinates for areasources, source height andgeographic detailsCan compute concentrationat max. 1200 receptorsRequire met data (winddirection, speed,Temperature, mixing heightand stability class)Model do not includebuoyant point sources,hence no plume risealgorithmCan take up to 35 colocatedpoint sourcesRequire source data andhourly met dataComputes concentration atmaximum 400 receptorsSuitable only for nonreactive gasesDo not include gravitationaleffects or depletioniv
