Short summary
It is a must to disentangle the contributions of stable meteorology from the effects of the COVID-19 lockdown. A 59 % decline in PM2.5 related to the COVID-19 pandemic was found in North China. The COVID-19 quarantine measures decreased the PM2.5 in the Yangtze River Delta by 72 %. In Hubei Province where most pneumonia cases were confirmed, the impact of the total emission reduction (72 %) evidently exceeded the rising percentage of PM2.5 driven by meteorology (13 %).
