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

Most glaciers currently decline because of the rapid climate change. This dataset aims to aid glacier research by providing glacier surface elevation estimates from radar altimetry. 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快速气候变化而处于消退态势。本数据集旨在通过雷达测高（radar altimetry）获取的冰川表面高程估算值，为冰川研究提供支撑。数据集涵盖北极地区所有已被收录于第7.0版兰多夫冰川目录（Randolph Glacier Inventory, RGI）的冰川。数据源自欧洲空间局（European Space Agency, ESA）的CryoSat-2卫星任务，该任务最适配面积达数平方公里的冰川观测。针对无有效观测数据的区域，我们采用统计方法完成插值补全。本数据集可用于解析单条冰川的动态变化特征，同时支持分析区域乃至北极全域的冰川变化趋势。
原始数据由欧洲空间局（ESA）提供。本数据集基于版本号为0.2.2的等效冰面测幅（cryoswath）流程生成。
