cal_soilSurfaceToMeanCanopyFlow {simET}

Calculating soil surface to mean canopy flow

Description

the resistance between the soil surface and the mean canopy flow (s m-1)

Usage

cal_soilSurfaceToMeanCanopyFlow(h, nK, Kh, zs0, z0, d)

Arguments

h

the plant height(m)

nK

the eddy diffusivity extinction coefficient (taken as 2)

Kh

eddy diffusivity at the canopy top(m2/s)

zs0

is the soil surface roughnesslength (m). Note: for flat, tilled land, zs0 can be taken as 0.004 m.

z0

the crop roughness length (m)

d

zero plane displacement height (m)

Value

A vector for aerodynamic resistancessoil surface to mean canopy flow (s m-1)
