Aerosol particles originating from the Qinghai-Tibet Plateau (QTP) readily reach free troposphere, potentially affecting global radiation and climate. Although new particle formation (NPF) is frequently observed at such high altitudes, its precursors their underlying chemistry remain poorly understood. This study presents direct observational evidence of anthropogenic influences on biogenic NPF southeastern QTP, near Himalayas. The mean nucleation rate (
