| 摘 要： | 为了研究南极冰盖消融对全球海平面变化的影响,利用2003年1月—2016年6月的重力恢复与气候实验时变重力场数据反演该地区冰盖质量变化,并采用去相关滤波P3M6加上300 km Fan滤波的组合算法削弱条带误差等影响,扣除冰后回弹和泄露误差影响.结果表明:南极地区冰盖质量变化整体表现为加速消融趋势,其质量变化率为(-101.27±7.02)Gt/a,其中西南极和南极半岛呈现质量消融,其质量变化率分别为(-148.35±6.78)Gt/a和(-22.01±1.44)Gt/a,而东南极表现为质量积累,其质量变化率为(69.09±2.64)Gt/a.

| Abstract: | In order to research the impact of mass change in the Antarctic ice sheet on global sea level change, ice sheet melting in this region are inverted by using the time-various gravity field data of Gravity Recovery and Climate Explorer from January 2003 to June 2016, and the combination algorithm of de-correlation filter P3M6 and 300km Fan filter is adopted to weaken the influence of stripe error,etc, then the ice rebound and leakage error are deducted. The results show that mass changes of the Antarctic ice sheet shows a trend of accelerated mlting, its mass changes rate is -101.27±7.02. Among them, The mass melting have appeared in Southwest Antarctic and Antarctic Peninsula,which are respectively -148.35±6.78 and -22.01±1.44, but mass accumulation, with mass changes rate 69.09±2.64, has appeared in Southeast Antarctic. |
