Tropical Pacific Ocean State Estimation (TPOSE)
TPOSE is a synthesis of observations of the tropical Pacific. It is produced by constraining a regional setup of the MIT general circulation model (MITgcm)
to fit data from Argo floats, moorings, and satellites through the adjoint method (4D-Var), resulting
in a physically-realistic estimate of the ocean state. For more information see

Results
TPOSE.6
A new higher-resolution state estimate is being produced. It has 1/6 degree horizontal resolution and 66 vertical levels, with 2 m thickness in the upper layers.
- Validation: model-observations comparison
TPOSE-bgc
- 1) the state estimate is coupled to a biogeochimal model (N-BLING). Validation: model-observations comparison
2) a 15-year forward model run. Validation: model-observations comparison. Data: monthly averages.
TPOSE.3
We have produced a state estimate at 1/3 degree resolution for the period 2010-2019. The output is publicly available (please cite appropriately). Some fields can be obtained by clicking on the links below; for additional diagnostics, please do not hesitate to contact us directly.
