Sea Surface Temperature (HYCOM Consortium/NOPP/GODEA, Daily)

Daily sea water temperature at a depth of 0m.

Water Temperature and Salinity are two products from the Hybrid Coordinate Ocean Model (HYCOM), created by the HYCOM Consortium, the National Ocean Partnership Program (NOPP), and the United States Global Ocean Data Assimilation Experiment (GODEA). HYCOM is a fully three dimensional, multivariate, variational ocean data assimilation system that produces simultaneous analyses of temperature, salinity, geopotential and vector velocity.

The analysis is run in real-time and updates daily. The data have been interpolated to a uniform 0.08 degree lat/long grid between 80.48°S and 80.48°N. The salinity, temperature, and velocity variables have been interpolated to 40 standard z-levels (vertical depth).

The high resolution makes HYCOM eddy resolving. Eddy-resolving models can more accurately simulate western boundary currents and the associated mesoscale variability and they better maintain more accurate and sharper ocean fronts. In particular, an eddy resolving ocean model allows upper ocean topographic coupling via flow instabilities. The coupling occurs when flow instabilities drive abyssal currents that in turn steer the pathways of upper ocean currents. In ocean prediction this coupling is important for ocean model dynamical interpolation skill in data assimilation/nowcasting and in ocean forecasting, which is feasible on time scales up to about a month.

Sea surface temperature (SST) retrievals are empiracally derived using stored regressions between cloud cleared satellite SST radiances and drifting buoy SSTs. The regressions are global, calculated once, and held constant.
