Abstract
The chemical compositions and size distribution of sea spray aerosols over West Pacific Ocean were determined by Signal particle aerosol mass spectrometer (SPAMS). The detection properties of sea salt aerosols using SPAMS were presented. The formation of sea salt aerosols and its impact factor were also investigated. The results show that the spatial distribution of sea salt particles was consistent with the total particles in the West Pacific Ocean, indicating that sea salt aerosols were the dominant sources of the aerosol particles in marine atmosphere. Sea salt aerosols were associated with the wind speed. High intensity signals of Mg+, Na+ and Ca+ were observed in the positive mass spectrum, which were considered to be derived from marine sources. HSO4? par-ticles were mainly concentrated on submicron size, accounting for more than 60% of the total particles. However, high Na relative fractions were observed both in small and large size. The size distribution of Ca+ particles was similar with the Cl? particles, which were mainly concentrated on large particles. The hit rate of sea salt aerosols was very different from the urban aerosol particles hit rate using the determination of SPAMS.
