This function calculates the Thermal Discomfort Index for a daily or hourly data series, based on the formula purposed by Thom(1959). Thom's index was created in 1959 at the U.S Weather Bureau in order to precise thermal discomfort levels. A chart containing the values and the discomfort level are presented on the link written at See Also section.

Calculates the Wind Chill index based on the NOAA's equation. Notice that this is an index to calculate how cold air feels on human skin. It is only effective for Wind Velocity values higher than 1.3 m/s and temperatures lower than 10 celsius
