摘要：

冰盖物质平衡状态对全球海平面具有重大影响, 是预测海平面上升的最大不确定性来源。近20年来随着卫星遥感技术的快速发展, 冰盖物质平衡研究取得巨大进展。研究系统介绍了近20年来冰盖物质平衡估算方法以及相应卫星数据的发展, 归纳和总结了国内外利用测高法、重力测量法、通量法和融合法进行南极和格陵兰冰盖物质平衡评估的结果, 详细分析了每种方法的不确定性和误差来源, 为未来冰盖物质平衡研究提供参考。冰盖物质平衡仍将是全球变化研究未来的重点, 提升卫星性能以降低观测数据的不确定性, 创新估算方法以降低估算结果的不确定性, 加强地面观测验证是研究热点。

Abstract:

Ice sheet mass balance is the biggest source of uncertainty in predicting sea level rise and has a large impact on global sea level. With the rapid development of satellite remote sensing, great progress has been made in ice sheet mass balance studies. This paper discusses the methods of estimating ice sheet mass balance and the development of satellite data, with detailed analysis of the uncertainty and sources of error for each method, and provides references for future ice sheet mass balance studies. The results of satellite altimetry, satellite gravimetry techniques, the input and output method, and the reconciled estimate method are also discussed. Ice sheet mass balance will remain a focus of global change research. Moreover, improving satellite performance to reduce the uncertainty of observation data, innovating estimation methods to reduce the uncertainty of results, and strengthening ground observation verification are expected to be future research hotpots.
