Abstract: Nowadays sand dust disaster and its effects on natural and social economic have attracted more and more attentions than ever before Since 1990s sand dust weather occurs more often in North China and strong sand dust storms bring more damage to the routine life of people in the local areas Meanwhile Asia dust can overpass the Pacific Ocean and transport to North America and pollute the air and environment of these regions Asia dust event becomes a hot spot in academic society of the world For the above reasons researches on sand dust have increased not only in world but also greatly in China Apart from traditional research method new technologies such as remote sensing have been used in the monitoring of sand dust disaster Since remote sensing technology can compensate the shortcomings in spatial and temporal resolution of conventional monitoring method Various satellite data with different spatial resolution, spectral resolution and temporal resolution can be used to monitor the sources of sand dust, the condition of land surface on its moving road and the climate background etcBut each sensor has its advantages and disadvantages so comprehensive research becomes more important and will be a new trend in sand dust research Quantitative information retrieval method of remote sensing will also be used in the research of sand dust disaster such as optical thickness of dust aerosol and characteristics of dust reflective and radiation Two of the most newly launched satellites are Terra and Aqua of NASA’s EOS plan The moderate resolution imaging spectroradiometer (MODIS) on board this two satellites have great potential in the study of sand dust disaster.

Key words: Remote sensing monitoring, Research progress, Sand-dust disaster
