Description:Much of the energy exchange between the air and the sea and within the marine planetary boundary layer is accomplished by turbulent fluxes of momentum, sensible heat and water vapor (latent heat). During the GARP Atlantic Tropical Experiment (GATE), the NOAA DC-6 equipped with a Gust Probe Turbulence System flew datagathering missions over the tropical Atlantic Ocean west of Africa. Flights were made on thirty days within the period from June to September 1974. The collected data are direct measurements of all three eddy fluxes at altitudes of 15 m to 3 km. This report contains basic results of statistical and spectral analysis of the fluxes from 440 samples of various durations. More specifically, this report includes the following: a descriptive log and data inventory with details of all flight paths, altitudes, and durations, and the corresponding weather; tabulations of calculated statistics for each flight leg, including the MoninObukhov length, means of water vapor density, temperature and the winds, mean vertical fluxes and flux variances, and the variance and frequency of the peak of each power spectra for each key parameter and corresponding flux; examples of the time series and power spectra; a case-study analysis to illustrate some of the utility of the various calculations; and calculations of overall mean sensible and latent heat fluxes for each phase of GATE.
