Abstract
In the present study, the atmospheric concentrations of various pollutants over the Indian subcontinent before the COVID-19 (during 2019) and during COVID-19 phases (2020) were studied. The COVID-19 has created a negative impact on the country’s economy but has positivity over the atmospheric resources. The levels of carbon monoxide (CO), nitrogen dioxide (NO2), and UV aerosol index were assessed using satellite images for the two different phases. The obtained results can be interpreted and can be substantiated with the lockdown effect due to the COVID -19 pandemic. The pollutants are mostly emitted from anthropogenic sources like vehicular emissions, industrial emissions, power plants, construction works, commercial and institutional places. It was evident that the levels of carbon monoxide, nitrous dioxide and aerosols levels have drastically decreased during the lockdown period. Hence, it can be concluded that COVID-19 has cleaned the atmospheric pollution as well as climate change scenario and nature on its own. © 2021 Technoscience Publications. All rights reserved.
