Abstract :

Air pollutants in Iran's metropolitan areas are among the serious challenges for managers, which also threatens the health of citizens. Monitoring air pollution is an important task in public health. Also, the unavailability of ground station data is often prevented due to the lack of network of ground monitoring stations to know the exact amount of air pollution in different parts of the country. Therefore, the use of remote sensing images in continuous monitoring of air pollutants due to their low cost and low manpower, will be appropriate and cost-effective. In this research, Sentinel 5 satellite images and MODIS sensors have been used for analytical study to detect the average trend of changes and spatial distribution of dust in Khuzestan province. The aim of this study was to use relatively high-resolution satellite data for local monitoring of air quality/air pollution and to investigate the relationship between Sentinel and MODIS image sensors. Findings indicate significant amounts of AOD in several parts of the study area such as Ahvaz, Abadan, Khorramshahr, BandarMahshahr and Bavi. Also, a small amount of fine dust is seen in the southeastern, eastern and northeastern cities of the province. According to the results of this research, as we move from the southeast, east and northeast and move towards the southern and western parts of the province, the amount of fine dust increases.
