Global Climate Risks for Outdoor Sports Under CMIP6 Scenarios

This repository contains the processed climate indicators used in the study “Global Climate Risks for Outdoor Sports Under CMIP6 Scenarios: A Multi-Indicator Assessment Based on WBGT, Heat Index, Heavy Rainfall, and Heatwaves”. The dataset provides gridded, impact-oriented indicators designed to quantify climate-related constraints on outdoor sport under historical and future climate conditions. Indicators were computed from bias-corrected daily CMIP6 projections from the NASA NEX-GDDP-CMIP6 dataset at 0.25° spatial resolution. Results are provided for the historical baseline period 1991–2020 and two future 30-year periods, 2031–2060 and 2071–2100, under SSP2-4.5 and SSP5-8.5. The repository includes three main indicators: Heat Index (HI): number of dangerous heat days, defined as days with Heat Index greater than or equal to 40 °C. This indicator captures combined heat and humidity conditions associated with severe apparent-temperature stress. Heavy rainfall days (RR20mm): number of days with daily precipitation greater than or equal to 20 mm day⁻¹. This indicator is used to represent rainfall-related constraints on outdoor sport, including surface degradation, disruption of play, and increased risk of event cancellation or postponement. Heatwave days (HW): number of days belonging to heatwave events, defined as sequences of at least three consecutive days with daily maximum temperature greater than or equal to 35 °C. This indicator captures cumulative thermal stress and multi-day periods during which repeated training, competition, recovery, and event organisation may be constrained. The indicators are aggregated by season, with separate outputs for boreal summer (JJA) and austral summer (DJF), and by 30-year analysis period. The dataset also includes derived values used to construct the Sport Climate Risk Index (SCRI), where applicable. The SCRI combines the normalized multi-hazard indicators into a composite index ranging from 0 to 1, with higher values indicating stronger combined climatic constraints on outdoor sport. These processed files constitute the minimal dataset required to reproduce the main results, maps, summary statistics, and figures reported in the manuscript. The associated analysis scripts and workflow are archived separately as a Zenodo software release.本仓库包含用于《CMIP6情景下户外运动的全球气候风险：基于湿球黑球温度（WBGT）、热指数、强降雨与热浪的多指标评估》研究的经预处理气候指标数据集。 本数据集提供网格化、面向影响的气候指标，用于量化历史及未来气候条件下对户外运动的气候相关限制。上述指标基于美国国家航空航天局（NASA）NEX-GDDP-CMIP6数据集经过偏差校正的每日CMIP6预测结果计算得到，空间分辨率为0.25°。数据集覆盖历史基准期1991–2020年，以及SSP2-4.5与SSP5-8.5情景下的两个未来30年时段：2031–2060年与2071–2100年。 本仓库包含三类核心气候指标： 热指数（Heat Index，HI）：危险高温日数，定义为热指数大于等于40℃的日期。该指标可表征伴随严重表观温度胁迫的热湿复合环境条件。 强降雨日数（RR20mm）：日降水量大于等于20 mm·day⁻¹的日期总数。该指标用于表征降雨对户外运动的相关限制，包括场地表层退化、赛事中断，以及赛事取消或推迟风险上升。 热浪日数（HW）：属于热浪事件的日期总数，热浪事件定义为连续至少3天日最高气温大于等于35℃的时段。该指标可表征累积热胁迫以及持续多日的时段——在此类时段内，重复开展训练、赛事、恢复活动及赛事组织工作均可能受到限制。 上述指标按季节聚合，分别输出北半球夏季（JJA）与南半球夏季（DJF）的结果，并按30年分析时段进行分类。数据集还包含用于构建户外运动气候风险指数（Sport Climate Risk Index, SCRI）的衍生指标（如适用）。SCRI将归一化后的多灾种指标整合为取值范围0至1的综合指数，指数越高代表户外运动面临的综合气候限制越强。 上述经预处理的文件为复现论文中报告的核心结果、地图、汇总统计数据与图表提供了最小必要数据集。相关分析脚本与工作流已作为Zenodo软件发布包单独归档。
