Abstract

The near-field effect on flux calculation was examined using two approaches: (1) The performance of a Lagrangian two-layer canopy model was compared with a K-theory two-layer canopy model and a K-theory single-layer canopy model; and (2) the near-field resistance was placed in series with aerodynamic resistance in the Canadian Land Surface Scheme (CLASS). The first approach was tested using flux data measured from a boreal aspen forest because it had a thick understorey canopy. The second approach was tested using the aspen forest and a Douglas fir forest. Results from both approaches confirmed that the difference between simulations from K-theory and the Lagrangian evaporation models was small due to the strong control by stomatal conductance. Furthermore, the two-layer canopy models were inferior to the single canopy model in the calculation of the sensible and latent heat fluxes above the forest.
