EvapHeat: Evaporative heat exchange between a wet surface and the surrounding air

Description

Evaporative heat exchange between a surface and the surrounding air [kJ m-2 d-1]. This function is only intended for wet surfaces, i.e., it assumes the vapor density at the surface is the saturation vapor density

Usage

EvapHeat(surftemp, airtemp, relativehumidity=NULL, Tn=NULL, wind=2)

Arguments

surftemp

surface temperature [C]

airtemp

average daily air temperature [C]

relativehumidity

relative humidity, 0-1 [-]

Tn

minimum dailiy air temperature, assumed to be dew point temperature if relativehumidity unknown [C]

wind

average daily windspeed [m/s]
