Characteristics of Aerosol WSI With High‐Time‐Resolution Observation Over Arctic Ocean
Abstract In the current study, the characteristics of aerosol water‐soluble ions (WSI) were investigated via high‐time‐resolution observations as part of the nineth Chinese National Arctic Research Expedition (CHINARE) in 2018. WSI, including Cl−, SO42−, NO3−, NO2−, F−, Br−, Na+, NH4+, K+, Ca2+, Mg2...

Sea salt ions (Na+ and Cl−) were observed to be the most dominant compounds, accounting for 53.5% of the total WSI, followed by the secondary ions (SO42−, NH4+, and NO3−), which accounted for 36.0%. Furthermore, similar spatial distributions of MSA− and SO42− were observed during the measurement period. High levels of Na+ were observed in the areas close to the land and Central Arctic Ocean, attributed to wind speed. In the open ocean, NH4+ and NO3− concentrations were extremely low, however, high levels of NH4+ and NO3− were observed in the coastal area close to Alaska and Russia.
