Yellow Sand Dust Event on 13 April 2003 over Western Kyushu, Japan

Abstract

A yellow sand dust (Asian dust; Kosa) event, which took place over Western Kyushu, Japan on 13 April 2003, was investigated using multiple observational data sets such as optical particle counters, sky radiometer, Mie-scattering lidar and intensive airplane observational equipments. The results of the present study show that the three-dimensional structure and the manner of transportation of dust particles on this day was very complicated especially in the vertical direction, and suggest that the spatial distribution of atmospheric aerosols over East Asia is occasionally very heterogeneous both in the horizontal and vertical directions.
