| 摘 要： | 利用GRACE时变重力场反演了2005年1～11月的中国及周边地区的水储量月变化,并对结果进行了分析。研究表明,利用GRACE时变重力场可以很好的对水储量进行监测,其监测能力足以揭示几个厘米的等效水高,为全球水循环及其气候变化提供了可靠的资料。 |
| 关 键 词： | 重力恢复与气候实验 重力场 水储量 |

| Abstract: | Based on the time-variable gravity field data of GRACE,we inversed the stock fluctuation of the water in China and its surrounding area between January and November in 2005.In the view of the fluctuation,we found the data of GRACE could be an effective monitoring on the stock fluctuation of the water,which have an accuracy of several centimeters as the equivalent water height.It is proved that the research of GRACE timely variable gravity field can provide credibility evidence for the study of global hydrological cycle observation and its effect on the climate alteration. |
