摘要 利用GRACE重力卫星提供的时变重力场反演了南极大陆冰雪质量变化。由于GRACE提供的C20项不准确,本文考虑利用SLR测得的C20项替换,反演结果显示南极西部冰雪在消融,东部基本保持平衡,整个南极以(-0.689±0.172)cm/a的速率在消融。 Using measurements of time-variable gravity field from the Gravity Recovery and Climate Experiment（GRACE） satellite, mass variations of the Antarctic ice and snow are estimated. Because C20 of GRACE is not accurate enough, C20 harmonic from Satellite Laser Ranging （SLR） is adopted instead. The results show that mass loses in West Antarctica, and mass is in balance in East Antarctica. And the rate of Antarctic mass loss is - 0. 689 ± 0. 172cm/a.
