Short summary

When emission controls were implemented during APEC, we found that the reduction in BC light absorption was driven by simultaneously reducing the mass concentration and light-absorption capability of BC. The weakening of BC light-absorption capability could be attributed to less coating material on BC surfaces due to the decreased chemical production of secondary aerosols. Our results imply that a synergetic reduction in multiple-pollutant emissions could benefit both air quality and climate.
