%X Recent studies have revealed a significant influx of anthropogenic aerosolfrom South Asia to the Himalayas and Tibetan Plateau (TP) during pre-monsoonperiod. In order to characterize the chemical composition, sources, andtransport processes of aerosol in this area, we carried out a field studyduring June 2015 by deploying a suite of online instruments including anAerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-AMS)and a multi-angle absorption photometer (MAAP) at Nam Co station(90 <sup>∘</sup> 57 <sup>′</sup>  E, 30 <sup>∘</sup> 46 <sup>′</sup>  N; 4730 m a.s.l.) at thecentral of the TP. The measurements were made at a period when the transitionfrom pre-monsoon to monsoon occurred. The average ambient mass concentrationof submicron particulate matter (PM <sub>1</sub>) over the whole campaign was ∼  2.0  µ g m <sup>−3</sup> , with organics accounting for 68 %,followed by sulfate (15 %), black carbon (8 %), ammonium (7&amp;t...
