Global Climate WBGT 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 four main indicators: Wet-Bulb Globe Temperature (WBGT): number of days exceeding sport-relevant heat-stress thresholds, computed separately for morning, afternoon, and evening conditions. WBGT is used to assess thermal stress combining air temperature, humidity, radiation, and wind-related assumptions relevant to outdoor sport exposure. 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.
