Abstract

Dust profiles have been observed by a laser Ceilometer (MEISEI CT25K) at Shapatou, China which is located at the edge of the Tengger Desert. The observation was conducted throughout one year of 2004 successfully and showed the behaviors of the atmospheric dust profile from near the surface to about the 1000-m height. The results of the observation were compared with several other meteorological data, such as surface, radio sonde and sky radiometer measurements. In particular, the dust profiles observed on calm and fair weather days were analyzed and compared with other meteorological data. The dust profile at the calm and fare weather day in the desert area is mainly influenced by thermal convection due to strong surface heating in the warm season. The dust amount lower than the 500-m height decreases in the daytime and recovers in the nighttime. The data of the sky radiometer shows that the total amount of the dust at the same calm and fair-weather days is almost constant during the daytime. The observational evidence was explained in the paper.
