Data assimilation for oceanography

  • Control vector \(\underline x\):

    • 3D fields : temperature, salinity, currents.

    • 2D fields : altimetry

    • One million of grid points

  • Observation vector \(\underline y\):

    • Satellite data: sea surface temperature,

    • In-situ data: temperature, salinity, currents

    • Serveral thousands of observations

Operational oceanography is more recent than operational meteorology. It shares common data assimilation methods.
