From ERA5-Land hourly data at 0.1° resolution
From ERA5 hourly data at 0.25° resolution
The 0.25° ERA5 data was bilinearly interpolated on ERA5-Land's 0.1°-grid. The spatial resolution is only used for uncertainty estimation. The closest grid point to the stadium is used.
For data and scripts used in Edouard et al. 2024, see /bjsm2024.
The universal thermal climate index (UTCI) is calculated with the polynomial approximation from the pythermalcomfort package. The 2m temperature and wind speed (=sqrt(u^2+v^) are directly used from ERA5-Land, the 2m dew point temperature is converted to relative humidity using the August-Roche-Magnus formula. The mean radiant temperature is calculated following Di Napoli, 2020 from surface solar and thermal radiation (net and downward) from ERA5-Land and ERA5.
