Vertical profiles of aerosol data and meteorological factor at Dunhunang in China were obtained by using observation instruments loaded in a remote-controlled airplane. The observations suggest that convective mixing of aerosols accumulated in the vicinity of the ground at nighttime is the main factor of diurnal variation of aerosol vertical distribution. Monthly-mean vertical distributions suggest that concentrations of fine particles and water vapor are higher in summer than in spring while those of coarse particles are lower in spring than in summer. During dust storms, number mixing ratio of coarse particles increased, while that of fine particles slightly decreased. The size distributions had two peaks. In the retreat periods of dust storms, the decreasing rates and speeds of number mixing ratios for the coarse and fine particles were different. These differences imply the different origins of the dust storms.
