Short summary
Recently, haze pollution has frequently occurred in North China. Therefore, we conducted synchronous measurements of PM2.5 for 1 year to investigate the haze formation mechanism, sources, and influences of regional transport. The results revealed that secondary aerosols, coal combustion, and motor vehicle exhaust exerted significant impacts on urban haze formation. The mitigation strategy of reducing gaseous precursors emitted from fossil fuel combustion was suggested.
