Short summary
This study presents a year-long PM2.5 study at Waliguan Baseline Observatory in the northeast of the Tibetan Plateau to investigate the optical properties of water-soluble brown carbon and its source. Our findings highlight that organic matter, sulfate, and nitrate are the dominant contributors to PM2.5 mass concentrations. Notable seasonal variations in the light absorption capacity of water-soluble brown carbon, accompanied by a high degree of oxidation are also observed.
