Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), Downscaled 1-km Grids, 2010-2100

The Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), Downscaled 1-km Grids, 2010-2100 consists of global spatial population projections at a resolution of one kilometer for urban, rural, and total population, consistent both quantitatively and qualitatively, with the Shared Socioeconomic Pathways (SSPs) at ten-year intervals for 2010-2100. Spatial demographic projections are key inputs for the analysis of land use, energy use, and emissions, as well as for the assessment of climate change vulnerability, impacts, and adaptation. The SSPs are developed to support future climate and global change research and the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). This data set includes a downscaled set of global spatial population projections at a resolution of 1-km (about 30 arc-seconds) for urban, rural and total population, and is distributed in GeoTIFF and netCDF formats.

基于共享社会经济路径（Shared Socioeconomic Pathways, SSPs）的降尺度1公里网格全球人口预测数据集（2010-2100年）包含分辨率为1公里的全球空间人口预测数据，涵盖城镇、乡村及总人口三类，在数量与质量层面均与2010至2100年每十年更新的共享社会经济路径（SSPs）保持一致。空间人口预测是土地利用、能源消费、碳排放分析，以及气候变化脆弱性、影响与适应措施评估的核心输入数据。共享社会经济路径（SSPs）的构建旨在支撑未来气候与全球变化研究，以及政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第六次评估报告（AR6）的相关工作。本数据集包含一套降尺度后的全球空间人口预测数据，分辨率为1公里（约30角秒），涵盖城镇、乡村及总人口三类，以GeoTIFF与netCDF格式发布。
