Physiological Equivalent Temperature (PET) and Wet-Bulb Globe Temperature (WBGT) index data from the Gothenburg half marathon.

Aim: To identify the thermal index that best predicts exertional heat incidence risk during a city half-marathon. Data: Eight years (2010-2017) of meteorological and ambulance transport data, including medical records, from Gothenburg’s half-marathon were used to analyze associations between WBGT, PET and UTCI and the rates of ambulance-required assistances (ARAs) and collapses. For more information, see the attached document "Data description". Meteorological data consisted of hourly averages of air temperature, wind speed, relative humidity, mean sea-level pressure, and incoming shortwave radiation. Thermal comfort indices are wet bulb globe temperature index (WBGT), Physiological equivalent temperature index (PET), and Universal thermal comfort index (UTCI).
