Data underlying the publication: Global Glacier Mass Loss During the GRACE Satellite Mission (2002-2016)

This collection contains mass changes for 17 glacier regions between 2002 and 2016 as time series and annual mass balances as published in: Wouters B, Gardner AS and Moholdt G (2019) Global Glacier Mass Loss During the GRACE Satellite Mission (2002-2016). Front. Earth Sci. 7:96. doi: 10.3389/feart.2019.00096 *** Time serie files GRACE_no_GIA_err.zip (= time series with GIA correction applied and cumulative GIA uncertainties INCLUDED in total uncertainties) and GRACE_no_GIA_noerr.zip ( = time series with GIA correction applied but cumulative GIA uncertainties NOT INCLUDED in total uncertainties): First column: files contain data (decimal years) Second column: mass anomaly w.r.t. arbitrary reference [Gigatonnes] Third column: uncertainty estimate [Gigatonnes] *** The annual mass balance files contain mass change between Mar 31 and Apr 1 and Sep 30 - Oct 1, respectively, for the 17 RGI regions defined in our Frontiers paper. Two files are provided, as total mass balance and specific mass balance.

本数据集收录了2002年至2016年间17个冰川区域的时间序列质量变化数据，以及年度质量平衡数据，相关成果已发表于：Wouters B、Gardner AS与Moholdt G（2019）《GRACE卫星任务期间（2002-2016）全球冰川质量损失》，刊载于Front. Earth Sci. 7:96，DOI: 10.3389/feart.2019.00096。

本次提供两类时间序列压缩包：GRACE_no_GIA_err.zip（已应用冰川均衡调整（GIA, Glacial Isostatic Adjustment）校正，且总不确定度已包含累积GIA不确定度）与GRACE_no_GIA_noerr.zip（已应用GIA校正，但总不确定度未纳入累积GIA不确定度）。两类文件的列格式统一如下：第一列为十进制年份数据；第二列为相对于任意参考基准的质量异常值，单位为吉吨；第三列为不确定度估值，单位为吉吨。

年度质量平衡文件对应前述《Frontiers》论文中定义的17个兰多夫冰川目录（RGI, Randolph Glacier Inventory）区域，其时间窗口分别为3月31日至4月1日，以及9月30日至10月1日。本次提供两类文件：总质量平衡文件与比质量平衡文件。
