Evapotranspiration and Carbon Flux
Evapotranspiration is the rate of transport of water vapor from the earth’s surface into the atmosphere. Evapotranspiration can be computed as reference, potential, or actual evapotranspiration. Reference evapotranspiration is that from a grass surface that is well-watered. Potential evapotranspiration is that from a surface that has unlimited water (such as a lake).
