The Eddy Dissipation Rate is an important metric for representing the intensity of atmospheric turbulence and is used as an input parameter for predicting the decay of aircraft wake vortices. In this study, the forecasts of eddy dissipation rates obtained from the current state-of-the-art mesoscale model are evaluated for terminal area applications. The Weather Research and Forecast mesoscale model is used to simulate the planetary boundary layer at high horizontal and vertical mesh resolutions. The Bougeault-Lacarrere and the Mellor-Yamada-Janjic schemes implemented in the Weather Research and Forecast model are evaluated against data collected during the National Aeronautics and Space Administration's Memphis Wake Vortex Field Experiment. Comparisons with other observations are included as well.
