Urban Heat Island Morning Traverse

This dataset contains data points along designated routes and captured near-surface air temperature on the morning (6-7am CST) on July 27, 2024. Traverse points were gathered by community volunteers and distributed by CAPA Strategies to support the National Oceanic and Atmospheric Administration’s Urban Heat Island Mapping Campaign. t_f = temperature in Fahrenheit rh = relative humidity hi_f = heat index* in Fahrenheit *Heat index is an approximation of the heat felt when the presence of humidity is felt in combination with temperature. For this project, the heat index was calculated by combining the temperature with the corresponding relative humidity measurement using the same equations as advised by the National Weather Service (CAPA Strategies, 9/2024)本数据集包含沿指定路线采集的近地表气温测点数据，采集时段为2024年7月27日上午（美国中部标准时间6至7时）。本次巡测点位由社区志愿者采集，经CAPA Strategies分发，用于支持美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration）的城市热岛测绘行动。 字段定义如下：t_f 代表华氏度单位的气温，rh 代表相对湿度，hi_f 代表华氏度单位的热指数（heat index）*。 *热指数是对湿度与温度共同作用下人体感知热度的近似估算值。本项目中，热指数通过结合实测气温与对应相对湿度数据计算得到，所采用的计算公式参考了美国国家气象局（National Weather Service）的指导方案（CAPA Strategies，2024年9月）。
