[ABSTRACT]We investigated particle size and shapes using in-situ observation and ground-based remote sensing data to characterize the Asian aerosols during Kosa events in particular. In this study, we analyzed the data observed in Fukue-jima island (32.6°N, 128.8°E) from 2003 to 2004. We estimated the particle size and sphericity using OPC and LIDAR observation data, respectively. We made a detailed match-up analysis based on the report of Kosa event at Fukue-jima by Japan Meteorological Agency. As a result, we have a linear relationship between particle size and sphericity in Kosa events, which is clearly different from the other seasons statistically. We further confirmed that larger and nonspherical particles were not exclusively dominated in Kosa events, compared to the other seasons. This also suggests that smaller and spherical particles, such as sea salts from the surrounding ocean or air pollution materials from mega cities, were mixed with Kosa aerosols statistically. We will further discuss the results with other match-up analyses using skyradiometry, and will compare the results to regional transport model simulations so as to identify the Asian aerosols around this region in detail.
