tmp_wet_bulb: Temperature, wet bulb

In WDNR-Water-Use/CSLSevap: Evapo(transpi)ration Calculations

Description

Calculates the wet bulb temperature as a function of actual vapour pressure, dew point temperature, and air temperature based on McJannet et al. (2008) Equation 25 as presented in McMahon et al. (2013) Equation S2.2

Usage

tmp_wet_bulb(atmp, RH)

Arguments

atmp	air temperature (degrees C). When dt is "daily" or larger, argument should be a list with elements "min" and "max" for daily min and max temperatures. When dt is "hourly", argument should be a vector with hourly recorded temperatures.
RH	relative humidity (percent). When dt is "daily" or larger, argument should be a list with elements "min" and "max" for daily min and max relative humidities. When dt is "hourly", argument should be a vector with hourly recorded relative humidities.

Value

wbtmp

the wet bulb temperature (degrees C)
