Primary Objective of this study is to discuss the effectiveness of COVID-19 on air pollution. We have collected data
from NASA, ESA (European Space Agency) and CPCB online portal for air quality data dissemination. The satellite images
from the above mentioned agencies elucidate that quality of air has improved causing reduction in the air pollution during
COVID-19.It was observed that Nitrogen Dioxide content was decreased in the air compared to same period last year. It suggests
that COVID-19 lockdown mitigated air pollution across the globe. We will discuss data of nitrogen dioxide content this data in
paper, and how much air pollution was controlled due to this lockdown
