资源简介:
The research project Short- and Long-Term Impacts of Climate Extremes (SLICE, 2019) entailed the provision of historical data and future projections of key hazard risk indicators for all project-relevant climate hazards in close collaboration with ISIMIP (www.isimip.org). In particular, the flood hazard indicators are of special interest for scientists and stakeholders and were applied in several risk assessments. The final report "UNDERSTANDING THE SHORT AND LONG-TERM IMPACTS OF CLIMATE EXTREMES" (Zimmer et al. 2023) summarizes project results and provides a detailed description of the flood data in its Technical Appendix.<br>The dataset entails historical simulations of annual river flood maxima (river discharge, flooded areas, flood depth), covering the time period 1971-2010, based on the input of climate reanalysis datasets (ISIMIP2a, Schewe et al. 2019) and future projections of annual river flood maxima (flooded areas, flood depth), covering the time period 2006-2100 complemented by simulations driven by historical GCM runs covering the time period 1860-2006 and pre-industrial control runs (ISIMIP2b, Frieler et al. 2017).<br>To derive spatially explicit flood hazard indicators, climate forcing data was processed by the ensemble of GHMs participating in ISIMIP2 harmonized with regard to their underlying river routing scheme by means of the global hydrodynamic model CaMa-Flood (v3.6.2 https://hydro.iis.u-tokyo.ac.jp/~yamadai/cama-flood/, Yamazaki et al., 2011). Data is provided assuming different levels of river flood protection including protection levels from the global database of FLOod PROtection Standards (FLOPROS, Scussolini et al. 2016).

气候极端事件短期与长期影响(Short- and Long-Term Impacts of Climate Extremes,缩写SLICE,2019年)研究项目,与跨部门影响模型比对项目(ISIMIP,www.isimip.org)紧密协作,为项目覆盖的各类气候灾害提供关键灾害风险指标的历史数据与未来预估数据。其中,洪涝灾害风险指标尤为受科研人员与利益相关方关注,并已被多项风险评估研究采用。最终报告《气候极端事件短期与长期影响解析》(Zimmer等,2023年)对项目研究成果进行了系统总结,并在其技术附录中详细阐释了本次发布的洪涝数据集细节。<br>本数据集包含两类模拟结果:一是基于气候再分析数据集(ISIMIP2a,Schewe等,2019年)驱动的1971-2010年年度河流洪涝极值(河流流量、淹没面积、淹没深度)历史模拟数据;二是2006-2100年年度河流洪涝极值(淹没面积、淹没深度)未来预估数据。此外,数据集还补充了由1860-2006年历史全球气候模式(Global Climate Model,GCM)试验数据驱动的模拟结果,以及工业前控制试验模拟结果(ISIMIP2b,Frieler等,2017年)。<br>为生成空间显式的洪涝灾害风险指标,研究团队借助全球水动力模型CaMa-Flood(v3.6.2,https://hydro.iis.u-tokyo.ac.jp/~yamadai/cama-flood/,Yamazaki等,2011年),对参与ISIMIP2的多模式集合全球水文模型(Global Hydrological Model,GHM)的河道汇流方案进行统一协调后,对气候强迫数据开展处理。本次发布的数据采用了不同等级的河流防洪标准,其中防洪等级数据取自全球防洪标准数据库(FLOPROS,Scussolini等,2016年)。

背景与挑战
背景概述
该数据集提供了基于ISIMIP2全球水文模型集合的全球河流洪水模拟,涵盖历史时期(1971-2010年)和未来预测(2006-2100年),包括河流流量、淹没面积和洪水深度等关键指标。数据使用CaMa-Flood水动力模型生成,并考虑了不同防洪保护水平,适用于气候极端事件的风险评估和研究。
