calc_stem_wp_response(stem_wp, wp_s50, c3)#

Calculates the restriction for NHL transpiration due to the hydrodynamic effects of xylem water potential. From eqn 2 of Mirfenderesgi et al 2016

Parameters:

  • stem_wp (float) – Stem water potential (function of z and time) [Pa]

  • wp_s50 (float) – Empirical shape parameter describing the inflection point of the leaf stem water potential response curve [Pa]

  • c3 (float) – Shape parameter for stomatal response

Returns:

wp_response – restriction for NHL transpiration

Return type:

float
