Short summary
This study focus on coal-combustion-dominated aerosol in urban areas in northwestern China and combines the results of optical measurement and chemical analysis to deduce the evolution of these characteristics in the atmosphere, which has previously been unknown. The results provide insights into the effects of atmospheric processes and emissions on brown carbon properties.
