We present here 10 years of in-situ data collected at a surface mooring located at 20° S, 85° W. Data are surface meteorology, from which bulk air-sea fluxes are estimated, and oceanography (temperature, salinity, currents). This allows for the discussion of air-sea interaction processes occurring locally and the effect on SPESTMW and ESPIW. For each observed field an annual cycle is estimated by averaging the long time-series. Inter-annual anomalies related to ENSO, as well as possible climate trends and finally signals from mesoscale eddies are also discussed.
This dataset is also put into a regional context with the help of gridded datasets for air-sea fluxes (such as OA Flux) and hydrography (such as ARMOR, CARS) that use satellite sensing and lagrangian floats.
