MONTHLY WATER DISTRIBUTION IN CHINA AND ITS ADJACENT AREA FROM TIME-VARIABLE GRAVITY FIELD OF GRACE
利用GRACE时变重力场监测中国及其周边地区的水储量月变化

On the basis of the time-variable gravity field data of GRACE,the monthly variation of the stock fluctuation of the water in China and its surrounding area is inversed between January and November in 2005.The results show that the stock fluctuation of the water can be monitored,with the accuracy of several centimeters of equivalent water height.It is proved that the timely variable gravity field of GRACE could provide credibility evidence for the study of global hydrological cycle and the climate alteration.
