Short summary
Severe haze events, with high particulate nitrate (pNO3) burden, frequently prevail in Beijing. In this study, we demonstrate a mutual-promotion effect between aerosol water uptake and pNO3 formation backed up by theoretical calculations and field observations throughout a typical pNO3-dominated haze event in Beijing wintertime. This self-amplified mutual-promotion effect between aerosol water content and particulate nitrate can rapidly deteriorate air quality and degrade visibility.
