20211005· Realtime composition of nonrefractory PM 1 particles (NRPM 1) was measured using an Aerodyne aerosol mass spectrometer (AMS) at a time resolution of min. The operational details on the AMS measurements have been given elsewhere (Xu et al., 2019). In addition, the measurements of gaseous species such as O 3, CO, NO, NO 2, and SO 2 were performed using gas analysers. The …
