Abstract
This study focuses on how the covid-19 pandemic impacts NO2 concentration in Kota City, Rajasthan (India), under different metrological conditions (Temperature, Precipitation, Relative Humidity, and Wind speed and direction). A reduction in NO2 concentration (-55%) was observed due to the Lockdown in Kota city. A sharp decrease of -37% in NO2 levels was observed in lockdown compared to the same period of 2019. However, a massive increase of 57% in NO2 levels was also seen in 2021 compared to the 2020 lockdown period. This study shows the lockdown effect on atmospheric composition, mainly through massive traffic and anthropogenic emissions reduction, significantly reducing NO2 concentrations. The findings can give confidence to stakeholders involved in air quality policy that if better pollution control plans are put in place and strictly implemented, pollution prevention can be done well. The natural environment and air quality have greatly improved due to lockdown. Keywords: Covid-19, Lockdown, Air Pollutants, NO2, Air Quality
