In-situ measurements for atmospheric DMS, its oxidative products, and aerosol size distribution at the King Sejong station in 2018–2020

To investigate the aerosolization process of DMS-induced particle, comprehensive in-situ atmospheric measurement (e.g., atmospheric DMS and aerosol properties) was conducted at King Sejong station during the productive summer period in 2018-2020. The atmospheric DMS mixing ratios were observed by using a custom-made trapping and desorption system equipped with pulsed flame photometric detector. The aerosol size distributions were measured by regular-SMPS (Scanning Mobility Particle Sizer). PM2.5 samples were collected by using a high volume sampler, and than the concentration of major ions (e.g., non-sea salt sulfate, methanesulfonic acid, and sodium) in PM2.5 particles were detected by ion chromatography.
