Impact of COVID-19 restrictions on the concentration and source apportionment of atmospheric ammonia (NH₃) across India.

ABSTRACT: The wide spread of the coronavirus disease (COVID-19) has significantly influenced human activities around the world, providing a unique opportunity to investigate the response of air pollution to anthropogenic emission reduction. Compared with numerous studies on conventional air pollutants, atmospheric ammonia (NH₃) that has matched sources from both anthropogenic and natural emissions has been rarely investigated. Here we assess impacts of the COVID-19 lockdown on ambient NH₃ variation across India, one of the most severe NH₃ pollution region in the world. The role of meteorology in shaping emission contribution to NH₃ pollution and respective contribution of each emission source to ambient NH₃ before and after the COVID-19 outbreak
