Optical, Physical and Chemical Properties of Aerosols around Japan Based on the R/V Shirase Shipboard Measurements

[ABSTRACT] In order to investigate the optical, physical and chemical properties of marine boundar layer aerosols and its relation to the origin of aerosols for estimating the direct radiative effect of aerosols in East Asia, shipboard aerosol measurements were carried out around Japan. The instrumented Research Vessel Shirase made counterclockwise coastal cruises from Yokosuka via the Western-North Pacific, the Sea of Japan, and the East China Sea in early autumns of 2002, 2003, and 2004. This paper includes results not only from optical measurements using an Optical Particle Counter, an Integrating Nephelometer, and a Particle Soot/Absorption Photometer but also chemical analysis of aerosols collected by an impactor-filter system. Water-insoluble aerosols were measured with a Coulter Counter. It was found that different features of optical, physical and chemical properties of aerosols in the marine boundary layer around Japan were strongly related to the origin and history of air mass.
