Development of a PC-based system for regional air quality modeling
- Applied Modeling Inc., Bell Canyon, CA (United States)
Several large urban areas throughout the world are plagued by severe air quality problems. One of the most common problems in photochemical smog of ozone which is formed under sunlight by chemical reactions between nitrogen oxides and volatile organic compounds. These primary pollutants are emitted by a wide range of emission sources, most notably mobile sources such as automobiles, stationary point sources such as power plants and oil refineries, and stationary area sources such as residential heating. A sophisticated three-dimensional Eulerian grid model is frequently used to predict the air quality impacts of existing or proposed emission sources, or to assess the effectiveness of emission control measures. Until recently, regional air quality modelling is computer-intensive and requires the use of a mainframe or a supercomputer. Large advances in computer technology in recent years have resulted in inexpensive personal computers and workstations approaching the speed of the supercomputers of a few years ago. This paper describes the development of a state-of-the-art modeling system named SMART (System for Modeling Atmospheric Release and Transport) which is suitable for a wide range of regional air quality impact analyses yet capable of running on these inexpensive computers.
