Short summary
In this study, we investigated the characteristics and changes in the sources of carbonaceous aerosols in northern Chinese cities using dual-carbon isotopes (13C and 14C) and levoglucosan during 2018 to 2019 and compared them with the research in previous decades. The results show that the contribution of fossil sources has decreased (6–16%) significantly, and non-fossil sources have become the main part of carbonaceous aerosols, which verified the effectiveness of air quality management.
