*UNWEIGHTED* Daily, County-Level Wet-Bulb Globe Temperature, Universal Thermal Climate Index, and Other Heat Metrics for the Contiguous United States, 2000-2020

This data set includes daily, <strong>unweighted</strong> mean values of various heat metrics for counties in the contiguous United States from 2000-2020. For applications involving human populations (e.g., public health), it is recommended to use the <em>population-weighted</em> data set instead. It has been accepted for publication at <em>Scientific Data</em>. Minimum, maximum, and mean ambient temperature, dew-point temperature, humidex, heat index, effective temperature, wet-bulb globe temperature, and Universal Thermal Climate Index are included. Note that Monroe County, Florida (FIPS: 12087) and Nantucket County, Massachusetts (FIPS 25019) are missing due to unavailability of ERA5-Land data for Key West, Florida and Nantucket, MA. <br> This data set is provided "as is," with no warranty whatsoever.
