OCARINA (Ocean coupled to the atmosphere: instrumented research on an auxiliary ship)
Résumé
Remote-controlled trimaran Ocarina (Océan couplé à l'atmosphère : recherche instrumentée sur navire annexe / Ocean coupled to the atmosphere: instrumented research on an auxiliary ship).The OCARINA platform (Ocean Coupled to the Atmosphere, Research on the Interface on the Annex Ship) is a surface naval drone specifically developed to measure turbulent and radiative exchanges at the ocean/atmosphere interface.Designed and produced at LATMOS in 2009, the initial version of OCARINA has evolved through campaigns and collaborations with DT-INSU, Ifremer, LOCEAN, and IRPHE.The onboard instruments are an inertial unit, a GPS, a sonic anemometer, a probe for measuring rising and falling radiative flows in the infrared and in visible wavelengths, a submerged probe of the CT type, and a meteorological station.The level 2 data provided are:the location, speed, heading and route followedthe height and significant period of waves longer than two metersthe water temperature (SST) at a depth of 30 cmsurface salinity (SSS)the meteorological variables (wind in modulus and direction, temperature, humidity and pressure) at one meter high.solar and infrared fluxes up and downturbulent bulk flows (u*, Hs and LE), and Monin-Obukhov's ratio (z/L)u* and Hsv (the turbulent buoyancy flux) estimated by the inertio dissipative methodu* and Hsv estimated by covariance method
