On the other hand, the concentration of NO 2 on the troposphere has a major effect on J o u r n a l P r e -p r o o f Although different studies have included a lockdown impact on improving air quality in urban areas, changes in air quality and air pollutants and the impact on the climate of microregions such as megacities have not yet been discussed. And to compare the pre-monsoon cloud-lightning activities affecting these air pollutants during the COVID-19 lockdown period and some pre-lockdown periods in the Kolkata megacity area.	./cache/cord-350919-by4zwniq.txt	./txt/cord-350919-by4zwniq.txt
