evapotranspiration

noun

Etymology: Blend of evapo(ration) + transpiration.

1. The transfer of water from the surface of the earth to the atmosphere by evaporation, sublimation and transpiration.

   “Calculated evapotranspirations are climatological values, namely the long-term average of the evapotranspirations.”

   “In many environments, evapotranspiration makes up a larger proportion of the catchment water balance than the stream discharge. Thus, for longer periods of rainfall–runoff simulation, it will generally be necessary to estimate actual evapotranspiration losses from a catchment in order to have an adequate representation of the antecedent state of the catchment prior to each rainfall event.”
