* Single Chimney Emission Analyzer (Air2.0) is a simple numerical tool for modeling and analyzing atmospheric dispersion, caused by single point source, on various Windows Platforms.

* The model is based on the formulations of Gauss and Holland, taking into account different environmental characteristics and conditions of source emissions.

* Air 2.0 supports three equations for estimating lateral and vertical dispersion coefficients.

* By using this analysis system, it is possible to determine various useful engineering parameters, such as permitted maximum pollutant load, which can be emitted from the chimney; pollutant concentration to a certain distance away from the emitting point; minimal inner diameter and lowest height of the chimney, and so on.

* With the help of this software, the user also can determine the size of a sanitary protectionstrip, related to air pollution.

Uses: Regional air quality analysis/evaluation for the effects of single chimney emission; various environmental engineering parameter determinations; also teaching courses relative to environment, air quality analysis and pollutant transport.
