    • Global High Resolution Daily Extreme Urban Heat Exposure (UHE-Daily), 1983-2016

    Metadata Updated: August 23, 2025

    The Global High Resolution Daily Extreme Urban Heat Exposure (UHE-Daily), 1983-2016 data set contains a high-resolution, longitudinal global record of geolocated urban extreme heat events and urban population exposure estimates for more than 10,000 urban settlements worldwide for 1983-2016. Urban extreme heat events and urban population exposure are identified for each urban settlement in the data record for five combined temperature-humidity thresholds: two-day or longer periods where the daily maximum Heat Index (HImax) > 40.6 �C; one-day or longer periods where HImax > 46.1 �C; and one day or longer periods where the daily maximum Wet Bulb Globe Temperature (WBGTmax) > 28 �C, 30 �C, and 32 �C. The WBGTmax thresholds follow the International Standards Organization (ISO) criteria for risk of occupational heat related heat illness, whereas the HImax thresholds follow the U.S. National Weather Services' definition for an excessive heat warning. For each criteria, across urban settlements worldwide, the data set also contains the duration, intensity, and severity of each urban extreme heat event.
