%X An intensive field measurement was conducted at a remote, background,high-altitude site (Qomolangma Station, QOMS, 4276 m a.s.l.) in thenorthern Himalayas, using an Aerodyne high-resolution time-of-flight aerosolmass spectrometer (HR-ToF-AMS) along with other collocated instruments. Thefield measurement was performed from 12 April to 12 May 2016 to chemicallycharacterize the high time-resolved submicron particulate matter (PM<sub>1</sub>)and obtain the dynamic processes (emissions, transport, and chemicalevolution) of biomass burning (BB), frequently transported from South Asia tothe Himalayas during pre-monsoon season. Overall, the average(±1 σ ) PM<sub>1</sub> mass concentration was4.44 (±4.54) µg m<sup>−3</sup> for the entire study, which is comparable withthose observed at other remote sites worldwide. Organic aerosol (OA) was thedominant PM<sub>1</sub> species (accounting for 54.3 % of total PM<sub>1</sub> on average) followed by black carbon (BC) (25.0 %), sulfate (9.3 %),ammonium (5.8 %), nitrate (5.1 ...
