Glacier surface elevation change rate dataset accompanying the article "Monthly surface elevation data of arctic mountain glaciers"

Most glaciers currently decline because of the rapid climate change. This dataset provides the glacier surface elevation change rates from radar altimetry presented in the accompanied article. The dataset includes all glaciers in the Arctic that are index in the Randolph Glacier Inventory (RGI) version 7.0. The data are derived from the European Space Agency's (ESA) mission CryoSat-2, which is best suited for glaciers covering several square kilometers. Where no observations were available we interpolated using statistical methods. The present dataset allows insights into dynamics of single glaciers, as well as into regional or Arctic-wide trends.<br>The source data were provided by the European Space Agency (ESA).The dataset was produced with cryoswath equivalent to version 0.2.2.

当前多数冰川因气候快速变化而呈现消退态势。本数据集提供了随附论文中基于雷达测高技术获取的冰川表面高程变化速率数据，涵盖北极地区所有被收录于第7.0版兰道夫冰川目录（Randolph Glacier Inventory, RGI）的冰川。该数据源自欧洲空间局（European Space Agency, ESA）的CryoSat-2卫星任务，该任务最适配覆盖面积达数平方千米的冰川观测。对于无有效观测数据的区域，我们采用统计方法进行插值补全。本数据集可用于解析单条冰川的动态变化特征，同时可支撑区域乃至北极全域的冰川变化趋势研究。原始数据由欧洲空间局（ESA）提供。本数据集基于版本0.2.2的CryoSwath工具生成。
