“…However, there is still a significant gap between the PM 2.5 concentration in northern China and its latest recommendations on air quality guidelines (5 µg m −3 ) by the World Health Organization (https://apps.who.int/iris/bitstream/handle/10665/ 345329/9789240034228-eng.pdf, last access: 26 November 2018; p. 78). In addition, severe PM 2.5 pollution still frequently occurred in northern China during wintertime (Guo et al, 2021;. To figure out the causes behind the pollution and further improve air quality in northern China, it is essential to use online hightime-resolution source apportionment technology to understand the chemical composition and source contribution of PM 2.5 in those pollution events.…”
