evapotranspiration

[i‚vap·ō‚tranz·pə′rā·shən]
(hydrology)
Discharge of water from the earth's surface to the atmosphere by evaporation from lakes, streams, and soil surfaces and by transpiration from plants. Also known as fly-off; total evaporation; water loss.

One of the advantages of the METRIC model compared to previous surface energy balance-based models for use in arid areas is that it utilizes reference evapotranspiration ([ET.sub.r]) for estimating actual evapotranspiration ([ET.sub.a]) at the cold pixel condition [10].

There were different model inputs including precipitation, seepage through irrigation system, return flow, recharge through water courses and evapotranspiration were distributed on all the cells of model grid according to their geographic location.
Irrigation was scheduled based on the crop evapotranspiration (ETc) calculated as follows:
