Yellow-sand events are the strongest natural signal of the long-range transport of air pollution. However, the state-of-art technology such as isentrophic trajectory models and satellite imaging techniques has limitations on the exact path or height of yellow-sand movement in the atmosphere. In this paper we are presenting the vertical profiles of the light extinction coefficient by the tropospheric aerosols measured by a micro pulse lidar, which clearly shows the height and thickness of yellow-sand movement. Aerosol size distributions and chemical compositions are also analyzed with an optical particle counter, a cascade impactor, ion chromatography, and an atomic absorption spectrometer.
