Monitoring changes in air pollution using Sentinel-5 data

Abstract

Today, air pollution is one of the most important issues in the field of environment and human health. In the last few years, remote sensing has helped a lot in the field of monitoring, measuring the concentration of pollutants. In this article, the monitoring of air pollution changes with Sentinel 5 satellite images in the southwest of Iran was discussed. Sentinel 5 images were received using the Google Earth Engine system in January 2022 to January 2023. After the detection of NO2, CO, UV-Aerosol and SO2, a map of atmospheric pollutants with color layers was obtained and then the one-year time changes of No2, Co, UV-Aerosol and SO2 were determined with a graph. The results of the graph of monthly changes showed that the concentration of NO2 and CO in spring and summer have the highest concentration, UV-Aerosol has the highest concentration in spring, and September and October have the highest concentration for SO2 in the center and southwest of Khuzestan province.
