utci: Universal Thermal Climate Index

In ClimInd: Climate Indices

Description

The Universal Thermal Climate is defined as the air temperature of the reference condition causing the same model response as actual conditions. The deviation of UTCI from air temperature, depends on the values of air and mean radiant temperature), wind speed and humidity.

Usage

utci(
  taverage,
  rh,
  w,
  tmrt,
  data_names = NULL,
  time.scale = YEAR,
  na.rm = FALSE
)

Arguments

taverage	daily mean temperature, Celsius
rh	relative humidity, percentage
w	average wind, m/s
tmrt	radiation temperature, Celsius
data_names	names of each period of time
time.scale	month, season or year
na.rm	logical. Should missing values (including NaN) be removed?

Value

index value
