mphtoms(wvmph=9.4)Discomfort Index
Description
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.
Usage
di(temp, ur)
Arguments
temp |
Numerical Vector of Mean Air Temperature values in celsius |
ur |
Numerical Vector of Mean Air Temperature values in celsius |
Value
Numerical vectors containing the Discomfort Index Values
