An implementation of the coupled photosynthesis - stomatal conductance model, using the Tuzet et al. (2003) model of stomatal conductance. Accepts all arguments of Photosyn (except gsmodel, of course).
PhotosynTuzet(g1 = 8, Ca = 400, psis = 0, kl = 2, sf = 3, psif = -2, ...)
| g1 | The slope parameter. Note that the default value should be much higher than that used in the Medlyn et al. (2011) model to give comparable predictions. |
|---|---|
| Ca | Atmospheric CO2 concentration. |
| psis | Soil water potential (MPa). Note that soil-to-root hydraulic conductance is not implemented. |
| kl | Leaf-specific hydraulic conductance (mmol m-2 s-1 MPa-1) |
| sf | Shape parameter (-) of sigmoidal function of leaf water potential (see Tuzet et al. 2003) |
| psif | Leaf water potential at which stomatal conductance is 50% of maximum (MPa). |
