Abstract：A case of long-distance transport of heavy dust pollution from west to east passing through Xinjiang, Qinghai, Gansu, Inner Mongolia, Ningxia, Shaanxi, Shanxi, Hebei, Beijing, Shandong, Jiangsu, Shanghai and Taiwan during March 28-April 2, 2007 was analyzed by using the lidar data onboard CALIPSO satellite. The optical parameters including back scattering coefficient, depolarization ratio, and color ratio were studied. Most large dust particles were near surface while relatively small ones stayed at middle and high altitude and had an even distribution. The lidar data from CALIPSO could reflect the vertical distributions of optical properties of dust aerosols as well as the features of particle size and irregularity varying with altitude during long-distance transport of heavy dust pollution.
