Abstract: Air pollution is a serious problem in densely populated and industrialized areas in some Asian countries. The area investigated for this study is Bangkok, Thailand. The air pollution in central Bangkok is significant in areas with high population density. To monitor air pollution over a large area, this research aims at developing a cost-effective and real-time air pollution monitoring system that utilizes numerical modeling in conjunction with inexpensive, state-of-the-art gas sensors, remote sensing methodologies, and Internet GIS. Conventional pollution detectors, installed by the Bangkok Pollution Control Department, as well as WO3 sensors are employed for in-situ pollution measurements. The data obtained from the satellites sensors and measurements conducted on ground are used for numerical modeling by “Multiple Regressions” to investigate air pollutants distribution. The analysis and correlation of the air pollutants data are transferred to a Personal Digital Assistant linked via Bluetooth communication tools and Global Positioning System for rapid and simultaneous dissemination of information on pollution levels at multiple sites.
