Data accompanying the article "Atmospheric-river-induced foehn events drain glaciers on Novaya Zemlya"

The glacier volume of the High Russian Arctic ice cap on Novaya Zemlya has been declining since the Little Ice Age. However, in the recent period, the loss of glacial ice has accelerated. We studied the glacier mass loss drivers by comparing the output of the regional atmospheric model MAR with observations from CryoSat-2, GRACE/GRACE-FO, and ICESat, and reanalysis results from ERA5 and MERRA2. We found that additional moisture import marjorly drives the mass loss increase; with foehn winds steering the transported energy to the lee-slope glacier surface. Here, we publish time series of modeled surface mass fluxes and moisture transport from reanalysis from 1980 to 2022, glacier mass change time series from observational data for different periods between 2002 and 2022, and the CryoSat-2 derived glacier surface elevation trends from 2011 to 2022 at a 500-by-500 m resolution. This dataset contributes to the reproducibility of the results, and can be compared to future datasets or used for further research.<br>The source data of CryoSat-2 derived products were provided by the European Space Agency (ESA).

新地岛（Novaya Zemlya）上的俄罗斯高纬度北极冰盖的冰川体积自小冰期以来便持续缩减，但近期冰川冰量流失速率显著加快。本研究通过对比区域大气模型MAR的模拟结果与CryoSat-2、GRACE/GRACE-FO及ICESat的观测数据，同时结合ERA5与MERRA2再分析结果，探究了冰川质量流失的驱动因子。研究发现，额外的水汽输入是质量流失加剧的主要驱动因素；焚风（foehn winds）将输送的能量引导至背风坡冰川表面。本数据集公开了1980年至2022年再分析模拟得到的地表质量通量与水汽输送时间序列、2002年至2022年不同时段观测数据得到的冰川质量变化时间序列，以及2011年至2022年分辨率为500米×500米的CryoSat-2反演冰川表面高程变化趋势。本数据集可为研究结果的可重复性提供支撑，亦可与未来数据集进行对比或用于后续研究。
