Satellite-derived velocity maps for Larsen C Ice Shelf, Antarctica, between November 2017-April 2019

Velocity maps were derived, for regions of Larsen C ice shelf, from satellite imagery spanning the period November 2017 to April 2019. This period was selected to monitor any change in the velocity field of Larsen C, in the months following the calving of iceberg A68 from the front of the ice shelf. The archive contains two sets of maps. The first are derived from Sentinel-1 satellite data, and span the complete ice shelf for the full 18-month epoch. The second are derived from TerraSAR-X data, and show high-resolution velocity trends between 2017 and 2018, covering the frontal region of Larsen C ice shelf. The maps were produced by Professor Adrian Luckman, Swansea University. The data is part of the NERC RACE project, NE/R012334/1.

本数据集针对拉森C冰架（Larsen C Ice Shelf）的相关区域，基于2017年11月至2019年4月时段的卫星影像提取得到速度图。选取该观测时段，旨在监测冰山A68从冰架前缘崩解后的数月内，拉森C冰架速度场的变化情况。本数据集存档包含两类速度图：第一类基于Sentinel-1卫星数据生成，覆盖整个冰架，涵盖完整的18个月观测周期；第二类基于TerraSAR-X数据生成，展示了2017年至2018年间拉森C冰架前缘区域的高分辨率速度变化趋势。上述速度图由斯旺西大学的阿德里安·拉克曼（Adrian Luckman）教授制作。本数据隶属于NERC RACE项目（项目编号：NE/R012334/1）。
