According to the radiative transfer characteristics and spatial distribution characteristics of dust particles, the occurrence, scope and strength of dust weather can be monitored effectively by using meteorological satellite data, and the quantitative information can be calculated. Generally, monitoring methods include the monitoring method based on the characteristics of satellite bands and the monitoring method based on satellite image visual interpretation. The dust monitoring module of the Satellite Monitoring Analysis and Remote Sensing Application Toolkit (SMART) can be used to achieve the annual statistics of dust monitoring results. The statistical data show that there are three high frequency dust weather areas which are xinjiang region; western Inner Mongolia and hexi corridor region; central and eastern Inner Mongolia, northeast and north China region. The cumulative coverage of dust areas monitored by satellite in 2007, 2010, 2012 and 2015 is larger, reaching over 5 million square kilometers. FY-4A, one of the new generation of stationary meteorological satellites, has exhibited its huge potential in dust monitoring. This will be beneficial to satellite image interpretation of dust weather.
