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
