Diurnal and temporal changes in air pollution during COVID-19 strict lockdown over different regions of India.

ABSTRACT: Lockdown measures to contain COVID-19 pandemic has resulted in a considerable change in air pollution worldwide. We estimate the temporal and diurnal changes of the six criteria air pollutants, including particulate matter (PM_2.5 and PM₁₀) and gaseous pollutants (NO₂, O₃, CO, and SO₂) during lockdown (25^th March - 3^rd May 2020) across regions of India using the observations from 134 real-time monitoring sites of Central Pollution Control Board (CPCB). Significant reduction in PM_2.5, PM₁₀, NO_2, and CO has been found in all the regions during the lockdown. SO₂ showed mixed behavior, with a slight increase at some sites but a comparatively significant decrease at other loca
