Air pollution monitoring using Sentinel-5 (Case study: big industrial cities of Iran)

Abstract

same is true for 2020. It is also clear that air pollution levels in Karaj and Kermanshah increased significantly in 2020 compared to 2019. Another significant finding is that, in general, air pollution levels in 2020 are lower than in 2019. One significant explanation may be the effect of the Covid-19 pandemic in 2020, which resulted in a decrease in industrial activity and reduced traffic and congestion on the roads. Conclusion: In general, the results of this research showed that it is possible to systematically monitor the air pollutants using images captured by TROPOMI sensor on the Sentinel-5 satellite with acceptable accuracy. The results of this study can help researchers and urban managers for appropriate management in metropolitan areas.
