摘要

本文对GRACE (gravity Recovery And Climate Experiment，重力恢复与气候实验)双卫星的重力数据进行了初步分析。数据包括重力数据，从2002年7月29日开始到2010年8月25日结束，以米为单位的10天最高值为1°× 1°等效水高(EWH)。集中在格陵兰岛的结果显示，统计上显著的质量损失被解释为内陆冰在东南和西北方向的融化，其中西北方向的融化加速，东南方向的融化可能减速。此外，有强烈的迹象表明，从2004年中到2006年初，格陵兰岛的大规模损失正在发生转变。

Greenland inland ice melt-off: Analysis of global gravity data from the GRACE satellites

This paper gives an introductory analysis of gravity data from the GRACE (Gravity Recovery And Climate Experiment) twin satellites. The data consist of gravity data in the form of 10-day maximum values of 1° by 1° equivalent water height (EWH) in meters starting at 29 July 2002 and ending at 25 August 2010. Results focussing on Greenland show statistically significant mass loss interpreted as inland ice melt-off to the SE and NW with an acceleration in the melt-off occurring to the NW and a possible deceleration to the SE. Also, there are strong indications of a transition taking place in the mass loss in Greenland from mid-2004 to early 2006.
