Supporting Environmental Data, Aggregate Results, and Code for Match-time Heat Exposure and Team Locomotor Output Across the 2025 Club World Cup and 2026 World Cup

The public archive includes a 167-match environmental and eligibility register, match-level exposure summaries, venue metadata, frozen aggregate results, selected analysis and figure-source code, environment information, provenance and rights documentation, and file hashes.</p><p><br></p><p dir="ltr">The main 2025 sample comprises 39 matches, 78 team-match records and 29 teams; the 2026 sample comprises 42 matches, 84 records and 39 teams.

Hybrid station observations pair with 39/39 and 34/42 main-sample matches, respectively. The confidence intervals for the 2026 primary slope and the tournament-by-exposure interaction both include zero.</p><p><br></p><p dir="ltr">The archive does not redistribute FIFA-derived team-match physical or tactical records, original official event files, exact PCA parameter matrices, or original hourly meteorological inputs. It therefore supports inspection of the reported aggregate results and selected methods, but cannot by itself reproduce the complete raw-input-to-model analysis.
