Xinjiang,far from the sea,is located in the middle of the Eurasian continent and sensitive to global change. In this paper,GRACE gravity satellites data were used to recovery the water storage variation of the Xinjiang. Based on the water storage variations,the water storage deficits were obtained and used to characterize the drought of Xinjiang during August,2002 and July,2013. The results showed that the drought characteristics of GRACE - based were consistent with the results of SPI. There were seven drought events in Xinjiang during August, 2002 and July,2013,and the drought event occurred in April 2008 and December 2009,was the worst one. GRACE provides for a new approach to drought monitoring,with good prospects.
