[MGI28-01] Analyzing the ocean with the latest ECCO Ocean State Estimate
Keywords:Ocean Circulation, Sea Level, Climate Change, Data Assimilation, Ocean Modeling
The new analysis has improved agreements with observations than before, allowing a more accurate accounting of processes contributing to their variation. In particular, the ECCO analysis is characterized by its physical consistency in the sense of the estimate’s temporal evolution being accounted for explicitly in terms of physical processes resolved by the model. The estimation’s infrastructure (e.g., model adjoint) allows analyses that cannot be easily performed from observations or models alone.
The new estimate and its infrastructure will be presented with a focus on sea level variations and associated changes in ocean heat and mass. Regional and vertical distribution of the variable heat and mass fields will be explored and the nature of their evolution will be examined in relation to the ocean circulation.
