Priestley and Taylor approach

The Priestley and Taylor approach is a simplification of Penman’s formulation of evapotranspiration ET, assuming that the equilibrium term λEeq is significantly larger than the aerodynamic term λEa. On the basis of this assumption, the Priestley–Taylor formulation for ET is expressed as λE = α λEeq where α is the so-called Priestley–Taylor coefficient.
