GlacioBasis Zackenberg - Glacier ice - AWS-Zack-M

Ice temperature profile at station Zack-M Glacier ice:Glacier ice GlacioBasis Zackenberg:Since 2008, the GlacioBasis programme has been monitoring the glacier surface mass balance at the A.P. Olsen Ice Cap and its response to climate forcing. Greenland’s glaciers and Ice Caps are losing mass at a rate more than double of the Ice Sheet when adjusted for size, accounting for 14-20 % of the total sea level rise contribution from Greenland. As the glaciological component of a core WMO GCW CryoNet site and a contributor to the GTN-G through WGMS, the GlacioBasis datasets complement the ongoing monitoring based at Zackenberg, enable process-based understanding of physical processes driven by glacier melt water run-off in the downstream terrestrial and marine ecosystems, and can inform regional and global assessments under AMAP and IPCC. GlacioBasis operates the year-round automatic monitoring of A.P. Olsen Ice Cap near-surface weather at three stations, a network of ablation stakes covering the entire altitude range, and geophysical survey campaigns on the ground (radar snow depth) and airborne (surface elevation from lidar, ice thickness from radar). GlacioBasis data collection is adaptively updated to support research in processes emerging as key sources of nonlinearity in the cryosphere, including melt water retention and albedo feedbacks. As a representative Northeast Greenland Ice Cap, A.P. Olsen observations delivered by GlacioBasis are available to the national and international remote sensing and climate modelling communities for calibration, validation and upscaling purposes.

扎克-M冰川站冰温廓线：格洛西奥拜西斯（GlacioBasis）扎科本基地冰川冰。自2008年起，GlacioBasis计划一直在监测A.P.奥尔森冰盖（A.P. Olsen Ice Cap）的冰川表面质量平衡及其对气候强迫的响应。格陵兰冰川与冰盖经面积校正后的质量损失速率是格陵兰冰盖的两倍以上，贡献了格陵兰总海平面上升贡献量的14%~20%。作为世界气象组织全球冰冻圈观测网络（WMO GCW CryoNet）核心站点的冰川学组成部分，同时通过世界冰川监测服务（WGMS）成为全球冰川监测网络（GTN-G）的贡献方，GlacioBasis数据集补充了扎科本基地的现有监测工作，助力基于过程的研究以解析下游陆地与海洋生态系统中由冰川融水径流驱动的物理过程，并可为北极监测与评估计划（AMAP）和政府间气候变化专门委员会（IPCC）开展的区域及全球评估提供科学依据。GlacioBasis 对A.P.奥尔森冰盖开展全年自动监测工作，包括布设3个近地表气象站、搭建覆盖全海拔范围的消融桩监测网，以及开展地面地球物理调查（雷达测雪深）与航空地球物理调查（激光雷达（lidar）测地表高程、雷达测冰厚）。GlacioBasis 的数据采集工作会进行适应性更新，以支撑冰冻圈关键非线性过程的相关研究，包括融水滞留与反照率反馈机制。作为东北格陵兰冰盖的典型代表，GlacioBasis 提供的A.P.奥尔森冰盖观测数据可面向国内外遥感与气候建模社区，用于校准、验证与尺度放大（upscaling）工作。
