Short summary
We used large-eddy simulations to test the sensitivity of roughness parameters to characteristics of canopy structure. We found that displacement height scaled with maximum canopy height, aerodynamic canopy height with maximum canopy height and leaf area index, and eddy-penetration depth with gap fraction. Using a decade of observations, we found that fixed parameterizations of roughness performed well but that empirical approaches that incorporated canopy structure preformed even better.
