Abstract:A total of 36 snow samples were collected and analyzed at 6 sites over the southeastern part of Qinghai Plateau. The results showed that the major color of the filters over these sites was yellow, indicating that the seasonal snow contained a large amount of dust. The BC concentration in the seasonal snow was (184±123)ng/g over the 6 sites. In addition, the BC concentration in surface snow ranged from 59ng/g to 238ng/g with an average of 152ng/g. Back trajectory clustering analysis, suggested that the air mass streams were mainly from South Asia and Tibet Plateau, and a small portion was from Taklimakan and Gobi desert.
