Application of air pollution models and remote sensing in Air Quality Management

Abstract :

The problem of air pollution in the atmosphere has attracted a new interest with the recent scientific evidence of the ill–health effects of air pollutants (gaseous and particulate). The monitoring of aerosol concentrations becomes a high environmental priority particularly in urban areas. They have several local and global environmental impacts. At the regional level, they reduces the visibility in the form of haze and to acid deposition, at the global level they play a role in climate change. So it is very important to monitor air quality. It is done with networks of ground monitoring stations and the use of various dispersion models that evaluate emissions and predict changes in air quality at separate points. The increasing availability of earth observing satellite systems and onboard imaging sensors together with advances in digital image processing techniques provide a new avenue to monitor urban air quality at a local and regional scale. Various air pollution dispersion models being used to predict the pollution load of an area for the current period and predict for the future. These models can be use in combination with the satellite models to have a good idea about any area. Thischapter highlight the use of various air pollution dispersion models and its combination with satellite helps in determination of air quality of any area particularly remote areas.
