    • United States Climate Reference Network (USCRN) Heat Indices

    Metadata Updated: September 19, 2023

    The U.S. Climate Reference Network (USCRN) was designed to monitor the climate of the United States using research quality instrumentation located within representative pristine environments. This heat index product is designed to provide heat index variables calculated hourly for each USCRN station location. Beyond the hourly average air temperature, relative humidity, and global solar radiation observed at the station, an hourly 10 meter wind speed average is estimated from station observations 1.5 meters above ground, and surface atmospheric pressure is extracted from either ERA5 reanalysis historically, or NCEP RUC in near real time. The file contains three heat exposure variables beyond air temperature: heat index (HI), apparent temperature (AT) and wet bulb globe temperature (WBGT). Air temperature and the three heat exposure indices have been provided in both metric (Degrees Celsius) and standard customary units (Degrees Fahrenheit) for convenience of the user.

    File names are structured at CRNHE0101-STATIONNAME.csv. HE stands for Heat Indices. The first two digits of the trailing integer indicate major version and the second two digits minor version of the product.

    Licence This dataset is available for only 114 station locations in the CONUS and stations in Alaska and Hawaii. In addition, conditions measured are representative of rural environments and not the conditions in urban centers.
    Lineage The dataset origin is internal to the U.S. Climate Reference Network Program at NCEI, taking quality controlled USCRN observations and using known formulae to calculate hourly air temperature, heat index, apparent temperature, and wet bulb globe temperature, for the purpose of understanding human heat exposure in outdoor rural environments.
