Local mass fluxes at the stomata (g_v,w,eff) as a function of the distance from the leading edge (x/L) at an air speed of 2 m s⁻¹ (Re_b = 1369) for different surface CRs: (A) this mass flux is scaled with the surface-averaged value over the leaf for a CR of 100 % (g_{v,w,avg,100 %}); (B) this mass flux is scaled with the local mass flux of each leaf segment of 0·1 mm for a CR of 100 % (g_{v,w,100 %}). BL (boundary layer) indicates the relative viscous sub-layer thickness distribution (δ_VSL/δ_VSL,avg) over the surface.
