get.zo_and_d model get.zo_and_d Calculates roughness length for momentum and zero plane displacement from vegetation height and LAI

Usage

get.zo_and_d(inputLUT, constants, calc.heat, calc.rss_rbs)

Arguments

inputLUT

list. Canopy structure inputs (vegetation height, LAI, etc.) for the roughness-length calculation.

constants

list. Physical constants used in the aerodynamic roughness formulation.

calc.heat

logical. Whether to include the heat-flux-related roughness adjustment terms.

calc.rss_rbs

logical. Whether to also compute soil/boundary-layer resistance terms alongside roughness length and displacement height.

Value

zo_and_d: a list with roughness length for momentum and zero-plane displacement height.
