Global One-Eighth Degree Urban Land Extent Projection and Base Year Grids by SSP Scenarios, 2000-2100

The Global One-Eighth Degree Urban Land Extent Projection and Base Year Grids by SSP Scenarios, 2000-2100 consists of global SSP-consistent spatial urban land fraction data for the base year 2000 and projections at ten-year intervals for 2010-2100 at a resolution of one-eighth degree (7.5 arc-minutes). Spatial urban land 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. This data set presents a set of global, spatially explicit urban land scenarios that are consistent with the Shared Socioeconomic Pathways (SSPs) to produce an empirically-grounded set of urban land spatial distributions over the 21st century. A data-science approach is used exploiting 15 diverse data sets, including a newly available 40-year global time series of fine-spatial-resolution remote sensing observations from the Landsat satellite series. The SSPs are developed to support future climate and global change research, the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6), along with Special Reports.

本数据集《基于共享社会经济路径（SSP）情景的全球八分之一度城市土地利用范围预测及基准年网格，2000-2100》包含全球基准年为2000年的SSP一致城市土地利用空间分数数据，以及以十年为间隔的2010-2100年预测数据，分辨率为八分之一度（7.5弧分）。空间城市土地利用预测是土地利用分析、能源消耗和排放分析的关键输入，也是评估气候变化脆弱性、影响及适应策略的重要依据。该数据集呈现了一组与SSP情景相一致的全局空间城市土地利用情景，旨在为21世纪的城市土地利用空间分布提供实证基础。数据科学方法被采用，利用包括来自Landsat卫星系列新近获得的40年全球高分辨率遥感观测数据在内的15个多样化的数据集。SSP情景的开发旨在支持未来的气候和全球变化研究，以及政府间气候变化专门委员会（IPCC）第六次评估报告（AR6）及特别报告。
