| 摘 要： | 基于CSR发布的GRACE时变重力场模型RL05数据，在频域上计算得到2002~2014年喜马拉雅山冰川质量变化。扣除GIA和水文模型影响后，喜马拉雅地区的冰川质量变化整体上呈现加速消融的趋势，消融速率约为-8.26±4.61 Gt/a，加速度约为-3.54±1.25 Gt/a2。

| Abstract: | The gravity recovery and climate experiment (GRACE) RL05 data from CSR is used to estimate glacier mass changes in the Himlayas from 2002 to 2014 based on mascon data in the spectral domain. The results show that the seasonal ice mass changes and long term ice mass changes can be determined from GRACE measurements in the Himalayas. During 2002-2014, after removing the impact of GIA and Hydrology, the mass change was -8.26 Gt/a, with an acceleration of -3.54 Gt/a2. |
