EvapHeat: Evaporative heat exchange between a wet surface and the...

In EcoHydRology: A Community Modeling Foundation for EcoHydrology

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]

Note

This function will use the relative humidity to esimate air vapor density if the value passed is between 0-1. Otherwise, it will assume the minimum daily air temperature is approximately the dew point temp.
