Short summary
The light absorption of BC-containing particles strongly depends on their aging process in the atmosphere. Whether and how the aging degree and light absorption capability of BC-containing particles will change with air pollution development is still unclear. Our results reveal that under a more polluted environment, the BC-containing particles are characterized not only by higher BC mass concentrations but also by more coating materials on BC surfaces and thus higher light absorption capacity.
