Abstract:

The impact of the COVID-19 Lockdown on SO2, O3, CO, particulate matters (PM10 and PM2.5), NO2, NOX, and NO over the capital city of Kerala (in India), Thiruvananthapuram, on Pre-lockdown phase, phase 1 of Lockdown, phase 2 of Lockdown and triple lockdown periods in 2019, 2020, and 2021 are studied. Because anthropogenic activities were reduced during the lockdown and air quality improved. AQI reduced by 25% and 26%, respectively, compared to the 2019 average value of AQI. The lower the AQI value indicates the influence of the Covid 19 lockdown on air quality.
