Wind-wave conditions of laboratory experiments in University of Hamburg's (Germany) wind-wave tank. A total of 20 wind-wave conditions were examined with varying wind speeds and three different surfactants deployed on the water surface. Experiments 1–5 were performed on a slick-free surface (no surfactant), experiments 6–10 with oleyl alcohol (OLA), experiments 11–15 with palmitic acid methyl ester (PME), and experiments 16–20 with toluol (TOLG). For each of the 20 experiment runs, the dataset lists the friction velocity and the 10 m extrapolated wind speed, together with wave parameters derived from the wire-gauge elevation time series under linear wave theory: wavelength, peak wave frequency, wave amplitude, wave age, dimensionless roughness length, and wave steepness.
