Annual damage maps of Antarctic Ice Shelves

This repository contains Annual Damage Maps of Antarctic Ice Shelves, obtained from processing remote sensing observations with the NormalisEd Radon Transform Damage (NeRD) Detection method. We detect damage on Antarctic ice shelves from SAR imagery for the years 1997, 2000, 2015, 2016, 2017, 2018, 2019, 2020, 2021; obtained from SAR data from the RadarSat mission (1997 and 2000) and Sentinel-1 EW GRD observations (2015-2021).<br>This repository provides the annual damage maps in two formats: netCDF and geotiff, organised in smaller spatial subsets for easier memory handling during data processing.<br>The damage maps are discussed in the the article "Damage development on Antarctic ice shelves sensitive to climate warming" by M. Izeboud, S.Lhermitte, S. de Roda Husman and B.Wouters, in review at Nature Climate Change, 2025. <br>The NeRD method is discussed in the article "Damage detection on antarctic ice shelves using the Normalised Radon Transform" by M. Izeboud and S. Lhermitte, Remote Sensing of Environment (doi: https://doi.org/10.1016/j.rse.2022.113359); available at github.com/mizeboud/NormalisedRadonTransform <br>More detail is included in the README file.<br><br>

本仓库包含南极冰架年度损伤地图，此类地图通过归一化拉东变换损伤（NormalisEd Radon Transform Damage, NeRD）检测方法处理遥感观测数据生成。我们基于合成孔径雷达（Synthetic Aperture Radar, SAR）影像，对1997、2000、2015、2016、2017、2018、2019、2020、2021年的南极冰架损伤开展检测；所用SAR数据分别来自Radarsat任务（1997年与2000年）以及Sentinel-1 EW GRD观测数据集（2015-2021年）。<br>本仓库提供两种格式的年度损伤地图：netCDF与地理标记图像文件格式（GeoTIFF），并按空间子集进行组织，以简化数据处理过程中的内存管理。<br>上述损伤地图相关研究成果为M. Izeboud、S. Lhermitte、S. de Roda Husman与B. Wouters撰写的《南极对气候变暖敏感的冰架损伤演化》，目前已投稿至《Nature Climate Change》（2025年），处于审稿阶段。<br>NeRD方法的相关细节见于M. Izeboud与S. Lhermitte发表于《Remote Sensing of Environment》的论文《基于归一化拉东变换的南极冰架损伤检测》（DOI: https://doi.org/10.1016/j.rse.2022.113359），配套代码可于github.com/mizeboud/NormalisedRadonTransform获取。<br>更多详细信息请参阅仓库内的README文件。
