The mean radiant temperature (MRT) and the Universal Thermal Climate Index (UTCI) are widely used as human biometeorology parameters to assess the linkages between outdoor environment and human well-being. Historically computed from meteorological station measurements, we here present ERA5-HEAT (Human thErmAl comforT), the first historical dataset of MRT and UTCI as spatially gridded records at the global scale. Derived using climate variables from ERA5, a quality-controlled reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) within the Copernicus Climate Change Service (C3S), ERA5-HEAT consists of hourly gridded maps of MRT and UTCI at 0.25° × 0.25° spatial resolution. It currently spans from 1979 to present, and it will be extended in time as updates of ERA5 are made available. ERA5-HEAT provides two streams, a consolidated and an intermediate one, that are released at 2 or 3 months and 5 days behind real time, respectively. Data are publicly and freely available for download at the Climate Data Store which has been developed as part of C3S. Being the only existing global historical gridded time series of MRT and UTCI to date, ERA5-HEAT is aimed at a wide range of end users, from scientists to policymakers, with an interest in environment–health applications at any spatial and temporal scale.

ERA5-HEAT：来自气候再分析的人类热舒适指数的全球网格历史数据集

平均辐射温度 (MRT) 和通用热气候指数 (UTCI) 被广泛用作人类生物气象学参数，以评估室外环境与人类福祉之间的联系。根据气象站测量的历史计算，我们在这里展示了 ERA5-HEAT（人类热舒适度），这是 MRT 和 UTCI 的第一个历史数据集，作为全球范围内的空间网格记录。ERA5-HEAT 使用来自 ERA5 的气候变量得出，这是由哥白尼气候变化服务 (C3S) 内的欧洲中期天气预报中心 (ECMWF) 制作的质量控制再分析，ERA5-HEAT 由 MRT 和 UTCI 在 0.25 的每小时网格图组成° × 0.25° 空间分辨率。它目前从 1979 年到现在，随着 ERA5 的更新可用，它将及时扩展。ERA5-HEAT 提供两个流，合并版和中间版，分别在实时发布后 2 或 3 个月和 5 天发布。数据可在作为 C3S 一部分开发的气候数据存储中公开和免费下载。作为迄今为止唯一存在的 MRT 和 UTCI 全球历史网格时间序列，ERA5-HEAT 面向广泛的最终用户，从科学家到决策者，对任何空间和时间尺度的环境-健康应用感兴趣。
