资源简介:
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.<br>The ISIMIP3a part of the third simulation round is dedicated to i) impact model evaluation and improvement and ii) detection and attribution of observed impacts according to the framework of IPCC Working Group II AR5 Chapter 18 and AR6 chapter 16. To this end all simulations are driven by observed socio-economic information combined with either observed (factual) climate data or a detrended (counterfactual) version of the observed climate allowing for the generation of a "no climate change" impact baseline.<br>We provide four factual climate input datasets for ISIMIP3a: GSWP3-W5E5, 20CRv3-W5E5, 20CRv3-ERA5, and 20CRv3. All of them have daily temporal and 0.5° spatial resolution. Their temporal coverage varies, with GSWP3-W5E5 and 20CRv3-W5E5 covering 1901-2019, while 20CRv3-ERA5 and 20CRv3 cover 1901-2021 and 1901-2015, respectively. For every factual dataset (obsclim) we provide an associated counterfactual dataset (counterclim) covering the same time period, 100 years worth of climate data to be used for model spin-up (spinclim), and 50 years worth of climate data for the transition from spinclim to counterclim or obsclim (transclim).<br>Version 1.1 fixes missing values in GSWP3-W5E5 snow fall input data (see https://data.isimip.org/caveats/26/).
跨部门影响模型比对项目(Inter-Sectoral Impact Model Intercomparison Project,ISIMIP)构建了一套跨部门、跨尺度的标准化气候影响数据整合框架,同时为通过统一情景探究跨部门气候变化影响的交互机制提供了独特的研究契机。
第三轮模拟中的ISIMIP3a模块主要聚焦两项核心任务:其一为影响模型的评估与优化;其二为依据政府间气候变化专门委员会(Intergovernmental Panel on Climate Change,IPCC)第二工作组第五次评估报告(AR5)第18章及第六次评估报告(AR6)第16章的框架,对已观测到的气候影响开展检测与归因研究。为此,所有模拟均以观测获取的社会经济信息作为驱动因子,并结合两类气候数据:一是观测得到的事实性气候数据(factual climate data),二是经去趋势处理的观测气候数据(反事实气候数据,counterfactual climate data),借此可生成“无气候变化”情景下的影响基准线。
本次为ISIMIP3a提供四套事实性气候输入数据集:GSWP3-W5E5、20CRv3-W5E5、20CRv3-ERA5及20CRv3。所有数据集均具备每日时间分辨率与0.5°空间分辨率。各数据集的时间覆盖范围存在差异:GSWP3-W5E5与20CRv3-W5E5的覆盖时段为1901—2019年,20CRv3-ERA5与20CRv3的覆盖时段则分别为1901—2021年与1901—2015年。针对每套事实性气候数据集(obsclim),我们同步提供了与之对应时段的反事实气候数据集(counterclim)、用于模型自旋初始化的百年时长气候数据(spinclim),以及用于实现从spinclim到counterclim或obsclim过渡的五十年时长气候数据(transclim)。
版本1.1修复了GSWP3-W5E5降雪输入数据中的缺失值问题(详见https://data.isimip.org/caveats/26/)。

背景概述
该数据集是ISIMIP3a项目的大气气候输入数据,主要用于气候影响模型的评估和改进,以及观测影响的检测和归因。它包含四种事实气候数据集(如GSWP3-W5E5和20CRv3-W5E5),均具有每日时间和0.5°空间分辨率,覆盖1901年起的长期序列,并配套提供反事实、启动和过渡气候数据,以支持'无气候变化'基线分析。数据集采用CC0 1.0许可,便于开放使用。
