Apparatus for Atmospheric Surface Layer Measurements over Waves

This paper describes an apparatus developed for simultaneously measuring water elevation and static and dynamic pressure, momentum, and heat fluxes above waves close to the interface. The apparatus was used successfully at the Lake Ontario wave research tower of the Canada Centre for Inland Waters. The principle and purpose of the various sensors used, calibration procedures, and data-gathering processes are described. Simultaneous measurements of the atmospheric surface layer’s physical quantities are presented. All the quantities necessary to close the kinetic energy budget in the atmospheric surface layer have been measured.
