Sapflux Density Equation (\(J_s\))

\[ J_s = 119 x (\frac{{\Delta}V_{max}}{{\Delta}V} - 1)^{1.231} \]

Two options for calculating dTmax:

  1. the pre-dawn ΔTmax (pd), where zero-flow is assumed to occur each night
  2. the environmental-dependent method (ed) assuming that one can find zero-flow conditions based on environmental conditions (Oishi et al., 2016)
