GlacioBasis Zackenberg - Near surface weather - AWS-Zack-M

Near surface weather at station Zack-M Near surface weather:Near surface weather 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站近地表气象 格拉克奥贝西斯(GlacioBasis)扎科恩观测场近地表气象：自2008年起，格拉克奥贝西斯项目便持续监测A.P.奥尔森冰盖(A.P. Olsen Ice Cap)的冰川表面物质平衡及其对气候强迫的响应。格陵兰的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，其贡献占格陵兰地区海平面总上升量的14%~20%。作为世界气象组织(WMO)核心冰冻圈网络(GCW CryoNet)站点的冰川学组成部分，并通过世界冰川监测服务(WGMS)纳入全球冰川监测网络(GTN-G)，格拉克奥贝西斯数据集补充了扎科恩观测场的现有监测工作，有助于基于过程理解冰川融水径流驱动的下游陆地与海洋生态系统物理过程，同时可为北极监测与评估计划(AMAP)及政府间气候变化专门委员会(IPCC)开展的区域与全球评估提供支撑。格拉克奥贝西斯项目在三处站点开展A.P.奥尔森冰盖近地表气象的全年自动监测，布设了覆盖全海拔范围的消融桩监测网，并开展地面（雷达测雪深）与航空（激光雷达测地表高程、雷达测冰厚）地球物理勘测工作。格拉克奥贝西斯的数据采集工作会进行自适应更新，以支撑冰冻圈关键非线性过程的相关研究，包括融水留存与反照率反馈机制。作为格陵兰东北部典型冰盖，格拉克奥贝西斯项目获取的A.P.奥尔森冰盖观测数据，可向国内外遥感与气候建模领域的科研人员开放，用于校准、验证与尺度提升工作。
