Evapotranspiration

As plants take in carbon dioxide for photosynthesis, they release water through evapotranspiration from their leaf pores, which helps them cool down in the hot sun.

Evapotranspiration is the sum of all processes by which water moves from the land surface to the atmosphere via evaporation 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.
