Another useful application of computer modeling tools is in predicting the impact of air pollution sources on local pollutant concentrations. A "quick and dirty" assessment of the likely impact of a new stationary source can be obtained through a screening program such as SCREEN3. A more sophisticated analysis, with multiple sources, can be made with a refined model such as ISCST3 or ISCLT3 (Industrial Source Complex Short- and Long-Term models).
This site will introduce the SCREEN3 model and its capabilities, and provide data and solutions to a few sample problems for those who wish to try out the program.
This software, along with other programs and much more information, is produced by the U.S. Environmental Protection Agency and can be downloaded from their Technology Transfer Network BBS by telnet. After you register and log on, go to the SCRAM (Support Center for Regulatory Air Models) area of the BBS. Both software and User's Guides can be downloaded here.
You might also want to telnet into the Research Triangle Park Online Library for more information.
A further source of government information on the subject is the Air Pollution Technology Branch of EPA. [Students of Professor Bungay's Environmental Systems Engineering course at RPI may be especially interested in their page describing work on Artificial Intelligence Control Research, where they discuss neural net and fuzzy logic controllers.]
