ISIMIP3b population input data

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 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 national and gridded historical population data for ISIMIP3b. Estimates are available for total as well as urban and rural population counts.

跨部门影响模型比对项目（Inter-Sectoral Impact Model Intercomparison Project，缩写ISIMIP）提供了跨部门、跨尺度整合一致气候影响数据的研究框架，同时为基于统一情景开展跨部门气候变化影响相互作用研究提供了独特契机。
第三模拟轮次中的ISIMIP3b部分，旨在量化不同全球增暖水平与社会经济变化情境下的气候相关风险。ISIMIP3b第一组模拟试验以耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，缩写CMIP6）模拟的历史气候变化，结合观测得到的历史社会经济强迫为基础；ISIMIP3b第二组模拟试验采用CMIP6给出的未来气候变化预估，同时将社会经济强迫固定于2015年水平；ISIMIP3b第三组模拟试验则额外纳入了社会经济强迫的未来变化。
本数据集包含ISIMIP3b所需的国家级与网格化历史人口数据，可提供总人口、城镇人口与乡村人口的数量统计估算值。
