Short summary
This paper presents a study on the severe air pollution in the winter of 2015 in China's Jing-Jin-Ji area. This triggered the first-ever red alert in the air pollution control history of Beijing, with an instantaneous PM2.5 concentration over 1 mg m−3. Analysis and modeling results show that the worsening meteorology conditions are the main reason behind this unusual increase in air pollutant concentrations.
