The impact of COVID-19 on urban PM_2.5 -taking Hubei Province as an example.

ABSTRACT: In January 2020, China implemented strict lockdown measures due to the invasion of the new coronavirus, which led to a sharp decline in the contribution of anthropogenic fine particulate matter (PM_2.5). The special period of COVID-19, especially in Hubei where the epidemic was the most severe, provides excellent research conditions for studying the contribution of anthropogenic activities to PM_2.5 concentrations. We used an optimized deep learning model to predict PM_2.5 concentration during the epidemic period in the cities of Hubei Province. The contributions of local anthropogenic activities to PM_2.5 pollution were obtained by contrasting the predicted results with actual site observations. However, a strange phenomenon was revealed that Yichan
