This work captured the changes in black carbon (BC) emissions from tightened pollution controls in a city cluster in eastern China through a top-down approach that incorporated available ground observations, chemistry transport model and multiple regression model. The uncertainty from a priori emission input and wet deposition was evaluated to be moderate. More ground measurements with better spatiotemporal coverage were recommended for constraining BC emissions effectively.
