Dispersion Modeling

Dispersion, Visibility, and Offsite Consequence Analysis Modeling Services

Atmospheric dispersion modelling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. Atmospheric emissions can have a direct impact on local receptors, therefore highlighting potential complications at an early stage is crucial. Modelling software allows variables, such as local topography, meteorological conditions, and site specific details such as building effects to be inputted allowing accurate and detailed results.

A wide selection of dispersion, visibility, and offsite consequence analysis models are available to evaluate multiple emission sources, these include the following:

EPA Air Quality Models: ISC3 (Short Term, Long Term), AERMOD, IGM, SCREEN3, INPUFF II

Offsite Consequence Analysis Models: SLAB, DEGADIS, ALOHA, SPILLS

Visibility Analysis Models: VISCREEN, PLUVUEII

Long Range Transport Modeling: MESOPUFF II, CALPUFF

Coastal Boundary, Flare, and Fumigation Models: SCREEN3, OCD

Transportation Source Models: CALINE3
