Short summary
NMHCs were measured during wintertime in Beijing to recognize their pollution levels, variation characteristics, and sources. The difference of the diurnal variations in NMHCs between clear days and haze days indicated that the relative contribution of vehicular emissions to NMHCs depended on the pollution status. Both the correlation coefficients of hydrocarbon pairs and PMF analysis revealed that coal combustion was an important source for atmospheric NMHCs, especially on haze days.
