Ozone (O3) formed from NOx and VOCs. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog. Ozone (O3) is a key constituent of the troposphere. It is also an important constituent of certain regions of the stratosphere commonly known as the Ozone ...

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 ...

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 ...

If you need help defining a case to be modeled, review of your input, or someone to do some non-regulatory modeling, we can help. Custom applications using the CHARM calculation engine can be developed. There is an Application Programming Interface (API) for each version of CHARM. The API allows embedding CHARM calculations into any Windows ...

Radicals (often referred to as free radicals) are atoms, molecules, or ions with unpaired electrons on an open shell configuration. Persistent free radicals connected to airborne fine particles could cause cardiopulmonary disease. Radicals, if allowed to run free in the body, are believed to be involved in degenerative diseases, senescence (the ...
