Interpretive Summary:

Technical Abstract: All measurements have random error associated with them. With fluxes in an eddy covariance system, measurement error can been modelled in several ways, often involving a statistical description of turbulence at its core. Using a field experiment with four towers, we generated four replicates of measurements at any given time. This study will give insight into the uncertainty of sensible and latent heat fluxes using the variability among the observations and simulations derived from the observations. Ultimately, the modeled uncertainty will be used to improve the evapotranspiration estimate relative to values from the field's large weighing lysimeter.
