Cover Story: Reductions in air pollution in Sydney under lockdown, though modest, were in striking contrast to the smoke-filled skies experienced during bushfires just months before. The drama of such changes was enhanced in iconic false-colour satellite images. Decreased use of transport and low electricity demand kept primary pollutant emissions low. People surveyed in Australia believed air pollution improved after lockdown, and searches on Google using terms such as air quality and haze were more frequent during the bushfires than under lockdown. Although changes in air pollutants during COVID-19 have been subtle, perceptions suggest dramatic improvements to air quality. View this paper
