With its 36 bands, Terra/MODIS has been widely used in atmosphere, water and land field monitoring. This paper deals with the operational method and technological process of sandstorm monitoring. It is pointed out that the addition of the analytical means based on two band bounds limits can be used as the operational method and that the technological process includes data preprocessing, information selection, grade classification, and comprehensive analysis. On the basis of the technological process and the method, sandstorm monitoring from April 8 to 11 in 2003 were carried out. The comparison between the result from NOAA-16 and that from FY-1C reveals its good effect. This research enriches the means of sandstorm monitoring and provides another data source and method for such monitoring, and hence the result obtained has operational potential.
