  l,
  PHI_p,
  Dm_v,
  lambda_p,
  THETA_v_l,
  THETA_v_sat_l
)

Arguments

tau

soil tortuosity (taken as 2)

l

is the dry soil layer thickness (taken as the first soil layer thickness) (m)

PHI_p

is soil porosity

Dm_v

the vapor diffusion coefficient in air (24.7 10-6 m2 s-1)

lambda_p

the soil pore-size distribution index from the Brooks-Corey equation.

THETA_v_l

volumetric soil water content (m-3 m-3) of the first soil layer

THETA_v_sat_l

saturated soil water content (m3 m-3) of the first soil layer

Value

A vector for the soil surface resistance (s m-1)
