Micrometeorological techniques have proven to be a very useful tool for making surface flux measurements because they provide near continuous, direct measurements without disturbing the surface. However, the underlying theory behind these techniques typically require that a site be horizontally homogeneous and fairly large (i.e., adequate fetch). In many circumstances where flux measurements are needed, these requirements cannot be met and few alternatives exist. In these situations it would be helpful to have a better understanding of the "practical" limitations of micrometeorological techniques because it may be possible to apply these methods to non-ideal surfaces yet still achieve acceptable results. Therefore, the goal of this study was to characterize the surface boundary layer of a non-homogeneous, fetch-limited surface by 1) calculating the roughness length and displacement height from measurements taken at different heights above the surface, 2) modeling the source area footprint of flux measurements, and 3) evaluating the impact of advection. Measurements were taken at a commercial cattle feedlot in central Kansas using Eddy Covariance techniques. This allowed us to determine the feasibility of Eddy Covariance and other micrometeorological techniques for flux measurements at cattle feedlots, and has implications for other non-homogeneous, fetch-limited surfaces.
