Short summary
Brown carbon (BrC), as an important component of aerosol, has attracted wide attention in recent years, yet very limited information on size differences is available. This paper reveals that BrC presented a bimodal pattern and was mainly derived from biomass burning in an interior city of China. Our results are very helpful for readers to comprehensively understand the features of brown carbon in China.
