The generation and evolution of eddies in the ocean are largely due to instabilities that are
unpredictable, even on short time-scales. As a result, eddy-resolving ocean reanalyses …

The GODAE OceanView systems use various data assimilation algorithms, including 3DVar,
EnOI, EnKF and the SEEK filter with a fixed basis, using different time windows. The main …

As part of the work of the GODAE OceanView Inter-comparison and Validation Task Team
(IV-TT), 6 global ocean forecasting systems spread across 5 operational oceanography …

The impact of the assimilation of HFR (high-frequency radar) observations in a high-
resolution regional model is evaluated, focusing on the improvement of the mesoscale …

Submesoscale dynamics are ubiquitous in the ocean and important in the variability of
physical, biological and chemical processes. Submesoscale resolving ocean models have …

We derive and apply a methodology for the initialization of velocity and transport fields in
complex multiply-connected regions with multiscale dynamics. The result is initial fields that …

In this study, we compare optimally interpolated monthly time series Tasman Sea XBT data
and a comprehensive set of ocean data assimilation models forced by atmospheric …

In comparison to the deep ocean, the upper mixed layer is a region typically characterized
by substantial vertical gradients in water properties. Within the Tropics, the rich variability in …

Seasonal prediction highly depends on its initialization scheme. Currently, the operational
utilization of advanced data assimilation methods in the oceanic initialization is still relatively …

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 …
