LE.to.ET {bigleaf}

Conversion between Latent Heat Flux and Evapotranspiration

Description

converts evaporative water flux from mass (ET=evapotranspiration) to energy (LE=latent heat flux) units, or vice versa.

Usage

LE.to.ET(LE, Tair)

ET.to.LE(ET, Tair)

Arguments

LE

Latent heat flux (W m-2)

Tair

Air temperature (deg C)

ET

Evapotranspiration (kg m-2 s-1)

Details

The conversions are given by:

ET = LE/\lambda

LE = \lambda ET

where \lambda is the latent heat of vaporization (J kg-1) as calculated by latent.heat.vaporization.

Examples

# LE of 200 Wm-2 and air temperature of 25degC
LE.to.ET(200,25)
