Journal ArticleDOI
A mean dynamic topography computed over the world ocean from altimetry, in situ measurements, and a geoid model
TL;DR: In this paper, a mean dynamic topography (MDT) is computed by subtracting the geoid model EIGEN-2 from the Mean Sea Surface Height CLS01, determined from 7 years of altimetric data (TOPEX and ERS1,2) at spherical harmonic degree 30.
Journal ArticleDOI
New CNES‐CLS09 global mean dynamic topography computed from the combination of GRACE data, altimetry, and in situ measurements
TL;DR: In this article, a new global 1/4° resolution mean dynamic topography (MDT) was computed for the 1993-1999 time period with improved data and methodology compared to the previous RIO05 MDT field.
Journal ArticleDOI
Beyond GOCE for the ocean circulation estimate: Synergetic use of altimetry, gravimetry, and in situ data provides new insight into geostrophic and Ekman currents
TL;DR: In this paper, ocean surface currents are estimated at two levels (surface and 15'm depth) as the sum of the geostrophic and Ekman components, and a new, global 14° Mean Dynamic Topography (CNS-CLS13) has been calculated and is now available for use by the oceanographic community.
Journal ArticleDOI
Mean Dynamic Topography of the Ocean Derived from Satellite and Drifting Buoy Data Using Three Different Techniques
Nikolai Maximenko,Peter Niiler,Marie-Hélène Rio,Oleg Melnichenko,Luca Centurioni,Boris Galperin,Don P. Chambers,Victor Zlotnicki +7 more
TL;DR: In this paper, three mean dynamic topography maps derived with different methodologies are presented, combining sea level observed by the high-accuracy satellite radar altimetry with the geoid model of the Gravity Recovery and Climate Experiment (GRACE), which has recently measured the earth's gravity with unprecedented spatial resolution and accuracy.
Journal ArticleDOI
The new ESA satellite‐only gravity field model via the direct approach
Sean Bruinsma,Christoph Förste,O. Abrikosov,Jean-Charles Marty,Marie-Hélène Rio,Sandrine Mulet,Sylvain Bonvalot +6 more
TL;DR: In this article, a satellite-only gravity field model to degree 260 using the direct approach, named DIR-R4, is presented, which is more accurate at low to medium resolution thanks to GOCE and GRACE data.
