ISIpedia country masks

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 AR5 Working Group II Chapter 18. 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” baseline.<br>The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical climate change as simulated in CMIP6 combined with observed historical socio-economic forcing. ISIMIP3b group II simulations are based on climate change according to the CMIP6 future projections combined with socio-economic forcings fixed at 2015 levels. ISIMIP3b group III simulations additionally account for future changes in socio-economic forcing.<br>This dataset contains the country masks from the ISIpedia project. The masks are available as binary or fractional maps on a 0.5° x 0.5° latitude-longitude grid. More formats are available at https://github.com/ISI-MIP/isipedia-countries.

跨部门影响模型互比项目（Inter-Sectoral Impact Model Intercomparison Project，简称ISIMIP）构建了一个框架，旨在跨部门和不同尺度上收集一套一致性的气候影响数据。此外，该项目还提供了一个独特的视角，通过一致的情景分析，探讨气候变化对各部门影响之间的相互作用。<br>ISIMIP3a作为第三轮模拟的组成部分，致力于对影响模型进行评估与优化，以及根据《政府间气候变化专门委员会第五次评估报告（IPCC AR5）工作组II第18章》的框架，对观测到的气候变化影响进行检测与归因。为此，所有模拟均由观测到的社会经济信息驱动，并结合观测的（事实性）气候数据或去趋势（反事实性）的观测气候数据，以便生成“无气候变化”的基线。<br>ISIMIP3b作为第三轮模拟的另一个组成部分，致力于量化不同全球变暖和社会经济变化水平下的气候相关风险。ISIMIP3b组I的模拟基于CMIP6模拟的历史气候变化，并结合观测的历史社会经济强迫。ISIMIP3b组II的模拟基于CMIP6的未来气候预测，并结合固定在2015年水平的社会经济强迫。ISIMIP3b组III的模拟进一步考虑了未来社会经济强迫的变化。<br>本数据集包含来自ISIpedia项目的国家掩码。掩码以二进制或分数地图的形式提供，覆盖0.5° x 0.5°的经纬度网格。更多格式可在https://github.com/ISI-MIP/isipedia-countries获取。
