Velocity and temperature fluctuations from multi-level measurements in the marine boundary layer were examined to determine the validity of present formulations and prediction techniques. Spectral distributions were analyzed using an analog analyzer as opposed to the digital computer methods previously utilized at the Naval Postgraduate School. In general, the height variations of the dissipation rate of turbulent kinetic energy, momentum flux, and the temperature structure parameter observed, in this study agree with the overland expressions developed by Wyngaard. Most deviations from expected results were attributed to apparent anomalies in spectral results. It has been shown that the analog spectral analysis performed in this study produced information which is as reliable as that from digital methods.
