In order to investigate the characteristic of optical properties of Asian dust particles, the atmospheric aerosol vertical profile was measured with the multi-wavelength LIDAR system, at the Gosan super site (33 degrees 17'N, 126 degrees 10'E) in Jeju Island, Korea, during the ACE-Asia intensive observation period, 11 March-4 May 2001. An air mass backward trajectory analysis, using Hysplit-4, was carried out to track the aerosol plume, with high mass loading, from the Chinese desert regions during the period of Asian dust storm events. Vertical atmospheric aerosol profiles on three major Asian dust storm event days, 22 March and 13 and 26 April 2001, have been analyzed. The LIDAR-derived aerosol optical depth values were compared with those measured by a collocated sunphotometer.
为了研究亚洲沙尘颗粒的光学特性，在2001年3月11日至5月4日亚洲沙尘气溶胶强化观测期内，利用多波长激光雷达系统在韩国济州岛的戈山超级观测站（北纬33度17分，东经126度10分）测量了大气气溶胶垂直剖面。利用Hysplit - 4进行气团后向轨迹分析，以追踪亚洲沙尘暴事件期间来自中国沙漠地区的高负荷气溶胶羽流。对2001年3月22日、4月13日和26日这三个主要亚洲沙尘暴事件日的垂直大气气溶胶剖面进行了分析。将激光雷达反演的气溶胶光学厚度值与并置的太阳光度计测量值进行了比较。
