Estimates of critical ground surface condition for Asian dust storm outbreak in Gobi desert region based on remotely sensed data

The Inland Asian dry land, such as Gobi and desert of Mongolian Plateau is the most important dust source region in the world. However, in recent years the dust storms were found to have been outbreak from the pastureland around the dry lakes, dry river channels and degraded pasturelands. Surrounding of dry lakes, dry river channels and degraded pastures are the main new sources of Asian Dust Storms (ADS). In this study, we measure of the Critical Ground Surface Condition (CGSC) (such as vegetation index (NDVI), soil moisture index, terrain roughness index, and soil particles) in ASD source region, with the influence on dust storm outbreak based on satellite data to evaluate the mechanism of ADS outbreak.
