Evaluating SODA for Indo-Pacific Ocean decadal climate variability studies
(Journal of Geophysical Research: Oceans, 2014-10-31)
Estimates of changes in upper ocean temperature, heat content, and sea level are dependent on the coverage of subsurface observations in space and time. Historically, these data are sparse, which has limited our understanding ...
Decadal Characterization of Indo-Pacific Ocean Subsurface Temperature Modes in SODA Reanalysis
(American Meteorological Society, 2015-04-29)
Studies of decadal-to-multidecadal ocean subsurface temperature variability are fundamental to improving the understanding of low-frequency climate signals. The present study uses the Simple Ocean Data Assimilation (SODA) ...
Oceanic data assimilation study in northern Chile: use of a 3DVAR methodAsimilación de datos oceánicos en el norte de Chile: uso de un método 3DVAR

Change in El Niño flavours over 1958-2008: Implications for the long-term trend of the upwelling off Peru
(Elsevier, 2012)
The tropical Pacific variability has experienced changes in its characteristics over the last decades. In particular, there is some evidence of an increased occurrence of El Niño events in the central Pacific (a.k.a. ...
A sequential data assimilation method based on the properties of a diffusion-type process
(2009)
Data assimilation method, as commonly used in numerical ocean and atmospheric circulation models, produces an estimation of state variables in terms of stochastic processes. This estimation is based on limit properties of ...
Slow westward movement of salinity anomalies across the tropical South Indian Ocean
(American Geophysical Union, 2015-08-06)
Decadal salinity variability is an important characteristic of the ocean. It characterizes differences in evaporative and precipitation fluxes at the surface, and in the subsurface it contributes to steric sea level change ...
Quantifying Antarctic deep waters in SODA reanalysis product
(Brasília, 2012)
The Antarctic intermediate and deep water masses present in the Atlantic sector of the Southern Ocean were quantified through the inverse method known as Optimum Multiparameter (OMP) analysis. The method was applied to the ...
Assessment of the structure and variability ofWeddell Sea water masses in distinct ocean reanalysis products
(2014)
We assessed and evaluated the performance of five ocean reanalysis products in reproducing essential hydrographic properties and their associated temporal variability for the Weddell Sea, Antarctica. The products used in ...
Estimation of the functional form of subgrid-scale schemes using ensemble-based data assimilation: a simple model experiment
(Wiley, 2016-10-02)
Oceanic and atmospheric global numerical models represent explicitly the large‐scale dynamics while the smaller‐scale processes are not resolved, so that their effects in the large‐scale dynamics are included through ...
