We assess and compare four sequential data assimilation methods developed for HYCOM in an identical twin experiment framework. The methods considered are Multi-variate Optimal Interpolation (MVOI), Ensemble Optimal Interpolation (EnOI), the fixed bas

The empirical relationship between salinity and temperature in the South Atlantic is quantified with the aid of local regression. To capture the spatial character of the TS relationship, models are fitted to data for each point on a three-dimensional

Some applications in remote sensing require estimating a field containing a discontinuity whose exact location is a priori unknown. Such fields of interest include sea surface temperature in oceanography and soil moisture in hydrology. For the former

he ocean is changing vigorously on a wide range of time and space scales. This variability leads to substantial problems in observing and modeling (simulating) the rapidly changing flow field, the ocean's temperature distribution, and more generally

Mean sea-surface temperatures were computed within 127 6°×4° longitude-by-latitude cells comprising most of the North Atlantic for 171 three-month seasons from 1950 to 1992, the mean seasonal cycle was removed, and cells with correlated seasonal a

Seeking an index characterizing the best-determined mode of variability leads to a natural generalization of principal-component analysis with an explicit metric characterizing the uncertainties of the data. This formalism, which distinguishes betwee

If indices are to be used as the variables predicted by linear statistical models, it is important to be able to recover as much local information as possible from the values forecast for the indices. Here it is shown that the indices that encapsulat

A broad partnership of institutions is collaborating in developing and demonstrating the performance and application of eddy-resolving, real-time global and basin-scale ocean prediction systems using the HYbrid Coordinate Ocean Model (HYCOM). These s

The purpose of this note is to point out that Hasselmann's optimal fingerprints for detecting climatic change follow from the geometrical interpretation of covariance as an inner product.

The long-term goal is to develop data-assimilating capability for HYCOM, the hybrid version of University of Miami s Isopycnic Coordinate Ocean Model. This project is one component of the NOPP consortium for developing a data-assimilating ocean model
