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.

当前绝大多数冰川因气候变化加速而处于消退状态。本数据集提供了伴随论文中所呈现的、基于雷达测高法得到的冰川表面高程变化速率。本数据集涵盖了《兰多夫冰川名录（Randolph Glacier Inventory, RGI）7.0版》中收录的所有北极地区冰川。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公里的冰川观测。对于无观测数据的区域，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运动变化规律，以及区域乃至北极全域的冰川变化趋势。<br>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。
