Air Dispersion Modeling Services

Air Dispersion Modeling is used by many regulatory agencies as a means of assessing the impact of a facility on the air quality of the surrounding area. In many instances, the results of an Air Dispersion Modeling study will be compared to legislated ambient or ground level air pollution criteria to determine the compliance status of a facility.

Air Dispersing Modeling Services

Air dispersion models are tools to assess impacts from air pollution sources. Why are these tools important? Air permit applicants must show that potential air quality impacts will not exceed specific health thresholds. If used before pollution sources are actually built, air dispersion models can be more advantageous than air monitoring.

Chlorofluorocarbons · air dispersion · consultants

However, the atmospheric impacts of CFCs are not limited to its role as an active ozone reducer. This anthropogenic compound is also a greenhouse gas, with a much higher potential to enhance the greenhouse effect than CO2.Infrared bands trap heat from escaping earth's atmosphere. In the case of CFCs, the strongest of these bands are located at the ...

NOx air dispersion · consultants

NOx is a generic term for the mono-nitrogen oxides NO and NO2 (nitric oxide and nitrogen dioxide). In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be quite significant. NOx gasses are formed everywhere where there is combustion, like in an engine. They ...
