Short summary
Highly time resolved chemistry and sources of PM1 were measured by an Aerodyne HR-ToF-AMS at Waliguan Baseline Observatory, a high-altitude background station at the northeastern edge of Qinghai–Tibet Plateau (QTP), during summer 2017. Relatively higher mass concentration of PM1 and dominant sulfate contribution were observed in this site compared to those at other high-elevation sites in the southern or central QTP, indicating the different aerosol sources between them.
