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

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.全球高分辨率每日极端城市热暴露（UHE-Daily）数据集，涵盖1983至2016年间全球范围内定位城市极端高温事件的纵向高分辨率记录，以及超过10,000个城市定居点的城市人口暴露估计。数据记录中针对每个城市定居点，根据五个综合温度-湿度阈值识别城市极端高温事件和城市人口暴露情况：连续两天或更长时间内每日最大体感温度（HImax）超过40.6°C；连续一天或更长时间内HImax超过46.1°C；以及连续一天或更长时间内每日最大湿球黑球温度（WBGTmax）超过28°C、30°C和32°C。WBGTmax阈值遵循国际标准化组织（ISO）关于职业热相关疾病的危险性标准，而HImax阈值则遵循美国国家气象服务部门关于极端高温预警的定义。对于每个标准，全球范围内各城市定居点的数据集还包含了每次城市极端高温事件的持续时间、强度和严重程度。
