public class ReferenceETPriestleyTaylor extends net.simplace.sim.model.FWSimComponent
Calculates reference evapotranspiration ET0 according to the Priestley-Taylor method, using solar radiation and temperature.

Priestley-Taylor (1972)

Uses the equation developed by Priestley and Taylor (1972) for ET0 calculation from temperature and solar radiation.

"The Priestley-Taylor equation was developed as a substitute to the Penman-Monteith equation to remove dependence on observations. For Priestley-Taylor, only radiation (irradiance) observations are required. This is done by removing the aerodynamic terms from the Penman-Monteith equation and adding an empirically derived constant factor, \alpha. (source: Wikipedia)
