calc_gb(uz, d=0.0015)#

Calculates the leaf boundary layer conductance and resistance, assuming laminar boundary layer.

Parameters:

  • uz (array-like) – wind speed at canopy height z [m s-1]

  • d (float) – characteristic leaf length [m]. By default 0.0015.

Returns:

  • gb (array-like) – leaf boundary layer conductance

  • rb (array_like) – leaf boundary layer resistance
