The Japan-China Joint Studies on Origin and Transport of Aeolian Dust and its Impact on Climate (ADEC) has started since April 2000. The purpose of ADEC is to figure out the mechanism of mineral dust outbreaks from arid regions into the atmosphere and to evaluate its annual variability. As a part of ADEC, a newly developed lidar has been operated since 2001 at the Aksu Water-Balance Station of Xinjiang Institute of Ecology and Geography, CAS, China. The present paper shows the vertical structure of the dust layer and high- and middle-level clouds over the Taklamakan Desert, using the lidar observations at Aksu during the spring in 2002 and 2003.
