Low-dimensional dynamical system model for observed coherent structures in ocean satellite data [PDF]

, 2000
The dynamics of coherent structures present in real-world environmental data is analyzed. The method developed in this Paper combines the power of the Proper Orthogonal Decomposition (POD) technique to identify these coherent structures in experimental ...

An Action Plan Towards Fiducial Reference Measurements for Satellite Altimetry

Remote Sensing, 2019
Satellite altimeters have been producing, as of 1992, an amazing and historic record of sea level changes. As Europe moves into full operational altimetry, it has become imperative that the quality of these monitoring signals with their uncertainties ...

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.

The Eddy Experiment: accurate GNSS-R ocean altimetry from low altitude aircraft

, 2004
During the Eddy Experiment, two synchronous GPS receivers were flown at 1 km altitude to collect L1 signals and their reflections from the sea surface for assessment of altimetric precision and accuracy.

Time-evolving mass loss of the Greenland Ice Sheet from satellite altimetry [PDF]

The Cryosphere, 2014
Mass changes of the Greenland Ice Sheet may be estimated by the input–output method (IOM), satellite gravimetry, or via surface elevation change rates (dH/dt).

Post‐Acquisition Image‐Based Localization for High Resolution Thermal and Visible/Shortwave Infrared Images With Application to the Lunar Trailblazer Mission

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Lunar Trailblazer mission aimed to assess the presence of water on the lunar surface using imaging spectroscopy in visible shortwave infrared (VSWIR) coupled with high‐resolution multispectral imaging in thermal midwave‐infrared (MWIR), captured simultaneously over the same target from orbit around the Moon with two different instruments ...

Preface to the Special Issue on Geodynamic and Climate-Change Processes over Tibet, Xinjiang and Siberia

Terrestrial, Atmospheric and Oceanic Sciences, 2011
Tibet, Xinjiang and Siberia (TibXS) are regions with active plate tectonics. Evidence from satellite gravimetry and altimetry shows the hydrological evolutions over these regions are sensitive to global climate change.

Shipboard Marine Gravimeters Operated on Vessels in the U.S. Academic Research Fleet: Capabilities and Data Quality

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Shipboard gravity anomaly data provide high‐resolution information for a wide range of Earth and ocean science research as well as ground‐truthing US national geodetic modeling. Motivated by the end of life‐cycle for legacy Bell aerospace marine Gravity Meter system (BGM‐3) gravimeters onboard vessels in the U.S. Academic Research Fleet, a new
