Urban heat islands

This dataset corresponds to urban heat islands. It 's made of a raster image with each pixel corresponding to a standardised Wet Bulb Globe Temperature (WBGT) indicator value from 0 to 100. This indicator measures heat stress based on temperature, humidity, wind, exposure to solar radiation and cloud cover for a typical hot summer day (i.e. 24 August 2016).本数据集围绕城市热岛（urban heat islands）效应构建，由一幅栅格图像（raster image）组成，图像内每个像素对应取值范围为0至100的标准化湿球黑球温度（Wet Bulb Globe Temperature, WBGT）指标值。该指标以气温、湿度、风速、太阳辐射暴露量及云量为计算依据，针对典型炎热夏日（即2016年8月24日）评估热应激水平。
