Antarctic Peninsula glacier front positions and ice-flow velocities

AntP_speed_geotiffs - geotiffs of ice flow velocity of 5 marine terminating outlet glaciers on the Antarctic Peninsula (Crane, Jorum, Hektoria, Drygalski and Cayley) between October 2016 and April 2018, derived from feature and speckle tracking of Sentinel 1a and 1b images. Front_positions - ice front positions for the same 5 marine terminating glaciers, mapped using the tool GEEDiT in Google Earth Engine. This analysis used cloud free Landsat 8 and Sentinel 1 and 2 imagery. Based on the paper by Tuckett, P.A., Ely, J.C., Sole, A.J., Livingstone, S.J., Davison, B.J., van Wessem, J.M., Howard, J. 2019.

AntP_speed_geotiffs：南极半岛5座海洋终结型外流冰川（Crane、Jorum、Hektoria、Drygalski及Cayley）在2016年10月至2018年4月期间的冰流速度GeoTIFF（GeoTIFF）数据，该数据集通过对Sentinel-1a与Sentinel-1b影像开展特征追踪与斑点追踪处理得到。Front_positions：针对上述5座海洋终结型冰川的冰前缘位置数据，通过谷歌地球引擎（Google Earth Engine）中的GEEDiT工具绘制生成，本次分析采用了无云的Landsat 8、Sentinel-1及Sentinel-2影像。本数据集基于Tuckett P.A.、Ely J.C.、Sole A.J.、Livingstone S.J.、Davison B.J.、van Wessem J.M.、Howard J.于2019年的研究成果，其论文题为《南极半岛外流冰川受表面融水驱动的快速加速》（原英文标题：Rapid accelerations of Antarctic Peninsula outlet glaciers driven by surface melt），将发表于《自然·通讯》（Nature Communications），目前处于待刊状态。
