Supporting data for "Damage development on Antarctic ice shelves sensitive to climate warming"

This repository contains supporting data for 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 in Nature Climate Change, 2025.<br>This repository is meant to help transparency and reproducibility. Included in this repository are (as discussed in the manuscript): (i) a list of all individually processed relative orbits of Sentinel-1 data to generate annual damage maps, (ii) annual ice shelf polygons used to clip the damage maps, (iii) aggregated damage values per ice shelf for all assessed years (1997, 2000; 2015-2021), (iv) the trained Random Forest model that was used to produce damage projections and (v) the projected damage values as presented in the article, obtained from the trained Random Forest regression model applied to ice sheet model data from models participating in the ISMIP-6 project (Seroussi et al, 2020)<br>Code used to process and analyse the data as discussed in the article, are provided on github.com/mizeboud/antarctic-damage-change/. The full dataset of annual Antarctic damage maps can be found at the other, linked, 4TU data repository.<br>More details are included in the README<br><br>

本仓库为M. Izeboud、S. Lhermitte、S. de Roda Husman与B. Wouters合著的2025年投稿于《自然·气候变化》待审论文《对气候变暖敏感的南极冰架损伤演化》提供配套数据集。
本仓库旨在提升研究的透明度与可复现性。仓库内含论文提及的以下内容：(i) 用于生成年度损伤地图的所有经单独处理的哨兵1号（Sentinel-1）数据相对轨道列表；(ii) 用于裁剪损伤地图的年度冰架多边形数据集；(iii) 所有评估年份（1997年、2000年、2015-2021年）内各冰架的聚合损伤值；(iv) 用于生成损伤预测的经训练的随机森林（Random Forest）模型；(v) 本文中展示的预测损伤值，该结果通过将训练好的随机森林回归模型应用于参与冰盖模型比对项目第六阶段（ISMIP-6）项目的冰盖模型数据（Seroussi等，2020）得到。
用于处理与分析本文所述数据的代码已发布于github.com/mizeboud/antarctic-damage-change/。完整的南极年度损伤地图数据集可在本仓库关联的另一4TU数据仓储中获取。
