TOPEX/POSEIDON is the first space mission specifically designed and conducted for
studying the circulation of the world's oceans. The mission is jointly conducted by the United …

We present PEGASE-HR, a new stellar population synthesis program generating high
resolution spectra () over the optical range= 400–680 nm. It links the spectro-photometric …

This paper deals with a new data assimilation algorithm, called Back and Forth Nudging.
The standard nudging technique consists in adding to the equations of the model a …

The sea surface elevation relative to the geoid, a dynamic boundary condition for the three-
dimensional oceanic pressure field, is being determined over the global ocean every 10 …

The ocean plays a key role in determining the global climate and its time evolution. To
understand this role and subsequently develop techniques for predicting future climate, one …

During the past 25 years, altimetric observations of the ocean surface from space have been
mapped to provide two dimensional sea surface height (SSH) fields that are crucial for …

抄録 Methods used to estimate the state of the ocean and its temporal variations with special
focus on the mesoscale (the eddy scale) are examined and illustrated. There are two broad …

Sea surface slopes from the altimetric satellites Geosat and TOPEX/POSEIDON are used to
calculate eddy kinetic energy of the North Atlantic subpolar gyre (40–65° N, 60°–5° W) …

In this paper, different types of new data sets (hydrography, Lagrangian and Eulerian current
measurements) and Quasi-Geostrophic model results, obtained after altimetric data …

We develop, analyze, and test an approximate, global data assimilation/synchronization
algorithm based on purely local observations for the two-dimensional Navier--Stokes …
