10 daily surface measurements over 90m transect, SSA, Density and Accumulation, from EastGRIP summer (May-August) of 2016-2019

Dataset containing surface snow measurements of snow specific surface area (SSA), snow density and snow accumulation. Surface samples were taken from the surface 2.5cm of snow. SSA measurements were determined using an Ice Cube measuring device (Zuanon, 2013). Snow density was measured from the SSA samples with a fixed volume. Snow accumulation describes the change in surface height at each sample site. All measured parameters have 10 daily samples taken at 10m intervals over a 90m transect. Sampling was carried out daily between May and August of 2016-2019, at approximately 24hr time intervals. All measurements were taken at the East Greenland Ice Core Project site (EastGRIP) situated in the accumulation zone of the Greenland Ice Sheet.

本数据集包含雪比表面积（Snow Specific Surface Area, SSA）、雪密度与积雪量的地表积雪实测数据。地表样本取自雪层表层2.5厘米的深度。雪比表面积的测量采用Ice Cube测量装置（Zuanon, 2013）完成。雪密度通过对SSA样本采用固定体积法进行测量。积雪量指各采样点的地表高度变化量。所有测量参数均在90米样带内以10米间隔采集样本，每日获取10组数据。采样工作于2016至2019年的5月至8月间每日开展，采样间隔约为24小时。所有测量均在位于格陵兰冰盖积雪积累区的东格陵兰冰芯项目站点（East Greenland Ice Core Project, EastGRIP）完成。
