Tropical Pacific State Estimation / Reanalysis

A regional setup of the MIT general circulation model (MITgcm) is constrained to fit data from the Tropical Pacific Observing System (TPOS; http://tpos2020.org). Data assimilation is accomplished iteratively through the adjoint method, resulting in a physically-realistic estimate of the ocean state. Tropical Pacific estimations are produced by Ariane Verdy, Matthew Mazloff, and Ganesh Gopalakrishnan. For more information see Vedy, Cornuelle, Mazloff, and Rudnick, 2017: Estimation of the Tropical Pacific Ocean State 2010-2013. J. Atmos. Oceanic Technol., 34, 1501-1517

The Tropical Pacific model domain is from 26S to 30N and 104E to 68W, with a resolution of 1/3 degree and 51 vertical levels.

Results from the 2010-2014 state estimate are available through this website or by contacting us directly.
