The change of turbulent kinetic energy and temperature dissipation rate within surface boundary layer

The experiments were conducted in the Air-Sea Interaction Saltwater Tank (ASIST) at the University of Miami, which was equipped with a turbulence generating grid and a heating grid. In our laboratory experiment, the internal decaying turbulence, the grid turbulence, was created by passing water through a solid grid. The friction between the moving water surface and the stationary air generated stress acting on the water surface. Here we call the value of the stressing wind velocity as "apparent wind velocity", which in turn equals the mean water flow velocity. We assume that the apparent wind velocity generated downstream propagating waves. In this experiment, free surface convection was found to be another source of near-surface turbulence. The velocity of the flow was measured with a current meter (Infinity-EM, Model AEM-USB), and the vertical microstructure profiler (VMP) was used to measure the turbulent kinetic energy dissipation rate and temperature dissipation rate. The VMP had two shear sensors and one temperature and one conductivity sensor. The data were collected on 2017-11-25, 2019-06-11 and 2019-06-12, and includes raw and processed current meter and VMP data and a selection of run conditions and parameter and unit explanations for each measurement. The related dataset on turbulent energy dissipation rates and wave decay of periodic non-breaking gravity waves is available under GRIIDC Unique Dataset Identifier (UDI) R6.x806.000:0035 (DOI: 10.7266/STH6HY6X).
