Abstract

This paper studied the marine-type aerosol distribution characteristics with the Wide-range Particle Spectrometer (WPS) obsevations boared on ”Shen Kuo” ship, over the South China Sea from June 21 to July 2, 2019. Particle spectral distributions at different time, fitted by the log-normal distribution method, and compared with the fine particle measurements in Hefei. Results show that the particle distributions over the South China Sea mainly show peaks around 95nm and 480nm respectively, while peaks around 26nm and 100nm in Hefei. The maximum concentration of fine particles in Hefei can reach 13×10³ /cm³ , which is much higher than that over the South China Sea with a peak concentration of 6×10³ /cm³ .
