Evapotranspiration (ET)
is the sum of evaporation and plant transpiration from
the Earth's land and Ocean surface to the atmosphere.
Evaporation accounts for the movement of water to the air
from sources such as the soil, canopy
interception,
and waterbodies.
Transpiration accounts for the movement of water within a plant and
the subsequent loss of water as vapor through stomata in
its leaves.
Evapotranspiration is an important part of the water
cycle.
An element (such as a tree) that contributes to
evapotranspiration can be called an evapotranspirator. |
