Overview of thermofeel

thermofeel is a thermal indices library, with the aim of allowing these indices to be integrated in numerical weather prediction systems. It was developed and is maintained by ECMWF (European Centre for Medium-Range Weather Forecasts).

It contains in total 16 methods including 11 thermal indices:

  • Relative Humidity (as water vapour pressure and percentage)

  • Solar Zenith Angle (Instantaneous and Integrated)

  • Mean Radiant Temperature (From radiation and Wet Bulb Globe Temperature)

  • Universal Thermal Climate Index (UTCI)

  • Wet Bulb Temperature

  • Globe Temperature from Mean Radiant Temperature

  • Wet Bulb Globe Temperature

  • Wet Bulb Globe Temperature Simple

  • Heat Index (Simplified and Adjusted)

  • Humidex

  • Net Effective Temperature

  • Apparent Temperature

  • Wind Chill
