Year-by-year, we have witnessed the advancement in the population count due to sudden urban expansion that had occurred in many countries. Due to urbanization, a lot of people have migrated to these areas from rural areas and from other countries. While this is good for the economy of the country, this has also increased the air contamination in the vicinity, and NO2 is one of the primary hazardous pollutants. It is monitored using the available remote sensing technology. For this paper, the data of NO2 is obtained from the latest satellite from the Sentinel series; Sentinel – 5 Precursor (5P) Satellite launched by European Space Agency (ESA) to detect the presence of pollutants at a tropospheric level using an on-board sensor – Tropospheric Monitoring Instrument (TROPOMI).
