HYPE give the option to exchange the default potential evaporation model for another model. Only the basic potential evaporation (<m>epot_base</m>) differs between models. Models 0-2 only use air temperature forcing. Models 3-5 want shortwave radiation and minimum and maximum daily air temperature, although if lacking approximations are made (see section [[start:hype_model_description:processes_above_ground#input_to_alternative_potential_evaporation_models|Input to alternative potential evaporation models]] below). In addition, model 5 wants relative humidity and wind speed if available. | HYPE give the option to exchange the default potential evaporation model for another model.
