| Abstract: |
| Air pollution is one of the main problems in human and environmental health in big cities and in developing countries. The precise monitoring and prediction of air quality and the assessment of the amount of contaminants will reduce the risks to human and the environment health. The particulate materials in the atmosphere are divided into two PM2.5 (particulate materials with a diameter of less than 2.5 µm) and PM10 (particulate materials with a diameter of less than 10 µm) groups, the main contributor to the air pollution associated with these pollutants. In this study, an experimental relationship is established between ground values of PM2.5 and PM10 with satellite images and a high-precision air pollution model is produced. Also, the impact of some urban parameters such as vegetation and traffic and important centres on air pollution have been the objectives of this research. Using four year course (From the beginning of 2015 until the end of 2018 from Tehran) from Landsat-8, OLI images and receiving ground data, at the same time, air pollution rates in different parts of Tehran have been investigated. For this purpose, 23 air quality control stations in Tehran have been used. The study suggests that the study of atmospheric reflectance from Landsat-8, OLI is a good alternative to monitoring the quality of air on Earth. |
