Inter comparison of Tropical Indian Ocean features in different ocean reanalysis products

Climate Dynamics, 2018
This study makes an inter comparison of ocean state of the Tropical Indian Ocean (TIO) in different ocean reanalyses such as global ocean data assimilation system (GODAS), ensemble coupled data assimilation (ECDA), ocean reanalysis system 4 (ORAS4) and simple ocean data assimilation (SODA) with reference to the in-situ buoy observations, satellite ...

SODA4: A Mesoscale Ocean-Sea Ice Reanalysis

2023
This paper introduces the new eddy-resolving global Simple Ocean Data Assimilation version 4 (SODA4) ocean/sea ice reanalysis. As with its predecessor SODA3, sequential data assimilation is used to constrain the evolving temperature and salinity fields using World Ocean Database profiles, in-situ and satellite sea surface temperature observations, and ...

A global ocean reanalysis product in the China Ocean Reanalysis (CORA) project

Advances in Atmospheric Sciences, 2013
The first version of a global ocean reanalysis over multiple decades (1979–2008) has been completed by the National Marine Data and Information Service within the China Ocean Reanalysis (CORA) project. The global ocean model employed is based upon the ocean general circulation model of the Massachusetts Institute of Technology.

Assessment of intraseasonal variabilities in China Ocean Reanalysis (CORA)

Acta Oceanologica Sinica, 2016
A regional reanalysis product—China Ocean Reanalysis (CORA)—has been developed for the China’s seas and the adjacent areas. In this study, the intraseasonal variabilities (ISVs) in CORA are assessed by comparing with observations and two other reanalysis products (ECCO2 and SODA).

Ocean reanalysis skill during the S-MODE pilot campaign

2022
An altimeter and glider assimilating ocean model was recently used to support NASA’s S-MODE pilot campaign: a science project designed to quantify mesoscale to submesoscale processes off the San Francisco Bay. There are several goals we intend to reach. The first is to demonstrate ocean prediction is limited by present observations.

An ocean data assimilation system and reanalysis of the World Ocean hydrophysical fields

Izvestiya, Atmospheric and Oceanic Physics, 2016
A new version of the ocean data assimilation system (ODAS) developed at the Hydrometcentre of Russia is presented. The assimilation is performed following the sequential scheme analysis–forecast–analysis. The main components of the ODAS are procedures for operational observation data processing, a variational analysis scheme, and an ocean general ...

Water Masses Analysis Based on Ocean Thermohaline Reanalysis Data

2020 12th International Conference on Measuring Technology and Mechatronics Automation (ICMTMA), 2020
The water masses are relatively stable at large scales. The spatial structure characteristics of water masses can be used as the basis of the data evalution standards demonstration. In this paper, water mass analysis methods such as cluster analysis and discriminant analysis are used, and the basic characteristics of water mass in the demonstration ...

Comparison of EnOI and EnKF regional ocean reanalysis systems

Ocean Modelling, 2015
Abstract This study compares two regional eddy resolving ocean reanalysis systems, based on the ensemble Kalman filter (EnKF) and ensemble optimal interpolation (EnOI), focusing on data assimilation aspects. Both systems are configured for the Tasman Sea using the same ocean model with 0.1° resolution and commonly available observations of satellite ...

Constraining Reanalysis Snowfall Over the Arctic Ocean Using CloudSat Observations

Geophysical Research Letters, 2020
In the absence of widespread snowfall observations over the Arctic Ocean, reanalysis products provide a wide range of estimates of time‐evolving snowfall rates over Arctic sea ice, and it can be difficult to determine which product is most representative.
