 TT11 Global Multidecadal Ocean Reanalyses from the Estimating the Circulation and Climate of the Ocean (ECCO) Consortium
[03-Mar-2022] This tutorial focuses on global multidecadal ocean state estimation: the challenge of reconstructing the three-dimensional, full-depth time-evolving ocean state by combining diverse satellite and in-situ ocean and marine ice data with numerical models in a rigorous and quantitative framework.

Challenges and recent progress in the field will be reviewed, with salient examples drawn from diverse projects from the "Estimating the Circulation and Climate of the Ocean" (ECCO) Consortium. By design, ECCO state estimates conserve heat, salt, and volume, which enable closed-budget analyses, a virtue that is critical for analyzing causal mechanisms of circulation changes on climate timescales.
Attendees will be shown how to obtain the latest ECCO ocean state estimates from NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) and provided resources for calculating closed heat, salt, and volume budget analyses, comparing the state estimates against observational data, and for re-running the open-source ECCO model for additional custom investigations. Open-source Python computational libraries and tutorials that facilitate ECCO analyses will be also introduced.
Finally, diverse climate science applications of ECCO ocean state estimates and its adjoint will be described with salient examples drawn from the recent literature.
