摘要

•A global observational analysis of air quality changes due to COVID-19 is presented.•NO2 decreased with heterogeneous changes in O3 and PM2.5 showing complex signals.•Urban oxidant was driven by primary NO2 and by regional inputs at background sites.•Meteorology, chemistry, emissions, climate and socioeconomics all affect air quality.•More ambitious regional regulation is needed to meet WHO air quality guidelines.
