We are conducting  a pilot study to evaluate methods for the estimations of aerodynamic roughness parameters (i.e., roughness length (z0), zero plane displacement height (d)) from single-level eddy covariance measurements. Results will guide development for future AmeriFlux and FLUXNET datasets.  Thanks to the flux community, most required variables are available through the AmeriFlux database (e.g., wind speed (WS),… More
