Short summary
In this work, we developed a new approach to simulate BC mixing state based on an emissions inventory and back-trajectory analysis. The model tracks the evolution of BC aging degree during atmospheric transport. Our simulations identified the important roles of extensive emission regions in the BC aging process during atmospheric transport, which provided more clues for improving air pollution and climate change.
