Short summary
Many Chinese cities now are suffering the high loadings of fine particular matters, which can bring a lot of negative impacts on air quality, human health, and the climate system. The Chinese government generally focuses on the control of the emissions from vehicles and industry. Our results evidently show that the burning of biomass materials such as wood and agricultural residues can lead to the urban air pollution in China. The characteristic of haze covering China is distinct from regions.
