PET equations

[stefano GECOs]

Is it possible to have more details concerning the equations beyond the evaluation of PET (Potential Evapotranspiration) made by different hydrological model?
Many Thanks !!!

The different evapotranspiration used by the different models is described in: Greuell, W., et al. “Evaluation of five hydrological models across Europe and their suitability for making projections under of climate change.” Hydrol Earth Syst Sci Discuss 12 (2015): 10289-10330.

To find out more about how the individual models have calibrated and/or validated evap you can then go into the publications behind each model. For E-HYPE the reference is Donnelly et al 2016 http://www.tandfonline.com/doi/abs/10.1080/02626667.2015.1027710#.V0wNaGd-PRY

E-HYPE and Lisflood are estimating evapotranspiration with the equation of Hargreaves and Samani (1985). In this equation radiation is
set equal to extraterrestrial radiation multiplied by a term representing atmospheric radiative transfer, which is parameterised as a function of daily maximum and minimum temperature

For VIC Evapotranspiration is calculated based on the Penman-Monteith equation
