A significant reduction in AOD over the North-Central regions (up to 50%) compared to the regions in the South or Northeast India. The AOD over these regions was significantly affected by the lock/unlock phases. It was also observed that there was a considerable buildup of AOD during the ...
First time in India, total lockdown was announced on 22 March 2020 to stop the spread of COVID-19 and the lockdown was extended for 21 days on 24 March 2020 in the first phase. During the total lockdown, most of the sources for poor air quality were stopped in India. In this ...

(2020) studied the COVID-19 effect in India. They analyzed the available data for primary air pollutants (PM2.5, NO2, sulfur dioxide (SO2) and CO from two major cities, Lucknow and New Delhi. Their analysis was based on air quality data pre-lockdown, and after lockdown periods of 21...
In this study, we characterize the impacts of COVID-19 on air pollution using NO2 and Aerosol Optical Depth (AOD) from TROPOMI and MODIS satellite datasets for 41 cities in India. Specifically, our results suggested a 13% NO2 reduction during the lockdown (March 25-May 3rd, 2020) ...
Similar decreases in aerosolconcentrations over Indo-Gangetic Plain (IGP) and south India during lockdown are noticed inModerate Resolution Imaging Spectroradiometer (MODIS) measurements, reaching the lowestvalues in the satellite era. Surprisingly, aerosol concentrations increased significantly (50–70%)...
Elsewhere in India, the impacts of lockdown have been identified in both chemical and biological water quality parameters within groundwater samples from the city of Thoothukudi (Tuticorin) (Selvam et al., 2020). However, to our knowledge, analyses of the impacts of the COVID-19 lockdown on...
