Nowadays, air pollution and its negative effects on human health is regarded as one of the most fundamental problems in the world. Iran as a developing country also deals with the issue of air pollution. Nitrogen dioxide (NO2) as one of the air pollutants leads to serious damage to the human respiratory system. The power plants are recognized as one of the main sources of producing NO2. In this research, the effect of NO2 produced in Shazand power plant on the air pollution in Arak metropolitan area, as one of the most polluted cities in Iran will be investigated using a third-order rational mathematical model. Sentinel-5 satellite images have been applied to monitor NO2 in the study area during the two years 2020-2019. The results indicate that the proposed model has been successful to model the relationship between the amount of NO2 produced in Shazand power plant and its propagation in Arak city using a set of control points with the values of RMSE, MAE and R2 equal to 6-10×2.1, 6-10×1.3 and 0.99 respectively. The results of model validation using check points with the values of RMSE, MAE and R2 equal to6-10×1.7 , 6-10×1.1 and 0.99 respectively indicate that the model can also be applied to any data location in the study area. |
