Air Dispersion Modeling

Air dispersion modeling is a sophisticated mathematical simulation of how air pollutants disperse in the atmosphere. Air dispersion modeling uses complex computer programs to calculate downwind concentrations of air pollutants emitted from sources such as industrial plants, combustion sources, vehicular traffic, or accidental chemical releases.Yorke Engineering, LLC’s (Yorke’s) environmental engineering staff expertly uses the latest modeling programs to solve complicated air dispersion modeling project objectives. Yorke’s expertise in air dispersion modeling spans a diverse mix of projects, including odor modeling, ambient air quality modeling, health risk assessment (HRA) modeling, and the modeling of mobile sources.
