“…During the lockdown period, across the globe, emissions from the transportation and industrial sectors were remarkably lower leading to a significant reduction in the levels of environmental pollution ( Arora et al, 2020 ; Muhammad et al, 2020 ; Paital, 2020 ). Numerous researchers (e.g., Collivignarelli et al, 2020 ; Dantas et al, 2020 ; He et al, 2020 ; Kanniah et al, 2020 ; Chin et al, 2020 ) have analysed data on environmental pollution (mostly air pollution) of different parts of the globe and have reported improvement in the ambient air quality levels during the COVID-19 lockdown. For India, researchers have similarly quantified the impacts of the nation-wide lockdown on the ambient air quality, using observed data from the ambient air quality monitoring stations ( Mahato et al, 2020 ; Sharma et al, 2020 ) as well as satellite-derived/reanalysis products ( Gautam, 2020 ) or a combination of both ( Lokhandwala and Gautam, 2020 ; Mahato and Ghosh, 2020 ; Selvam et al, 2020 ).…”
