Short summary
This study reveals an obvious decreasing trend in OC and EC concentrations in urban Beijing. Higher concentrations were related to air masses originating from the northeast sector at wind speeds of approximately 5 km h−1. The potential source regions of the carbonaceous aerosols stretched to broader areas in the northwestern and western regions where coal mining and coal-fired power generation activities are intensive, which is fairly consistent with the MEIC inventory for China.
