Short summary

Generally, atmospheric pollutants exhibit seasonal and annual variations with space and time in addition to episodic events. Hence it is important to quantify the changes that occurred due to episodic events such as lockdown in this case. Therefore in our study, we intended to show the lockdown-induced changes of tropospheric NO₂, carbon monoxide (CO), and AOD in addition to the effect of inter-annual variability on these pollutants. Further observed changes were statistically evaluated.
