Envisat RA-2 Individual Echoes: A Unique Dataset for a Better Understanding of Inland Water Altimetry Potentialities

open access: yesRemote Sensing, 2017
The exploitation of synthetic aperture properties in nadir-looking radars is opening new scenarios in the framework of satellite radar altimetry. Both recent and upcoming missions including Cryosat-2, Sentinel-3, Sentinel-6 and SWOT take benefit from the

Understanding uncertainties in the satellite altimeter measurement of coastal sea level: insights from a round-robin analysis [PDF]

open access: yesOcean Science
The satellite radar altimetry record of sea level has now surpassed 30 years in length. These observations have greatly improved our knowledge of the open ocean and are now an essential component of many operational marine systems and climate studies ...

Antarctic ice shelf thickness from CryoSat‐2 radar altimetry [PDF]

open access: yesGeophysical Research Letters, 2015
AbstractIce shelf thickness for the whole of Antarctica is derived from 4 years (2011–2014) of CryoSat‐2 (CS2) radar altimetry measurements using the assumption that the shelves are in hydrostatic equilibrium. The satellite orbit and novel synthetic aperture radar interferometric mode of CS2 results in 92.3% data coverage over the ice shelves, with ...

Ocean Surface Topography Altimetry by Large Baseline Cross-Interferometry from Satellite Formation

open access: yesRemote Sensing, 2020
Imaging Radar Altimeter (IRA) is the current development tendency for ocean surface topography (OST) altimetry, which utilizes Synthetic Aperture Radar (SAR) and interferometry to improve the spatial resolution of OST to several kilometers or even better.

Antarctic Grounding Line Mapping From CryoSat‐2 Radar Altimetry [PDF]

open access: yesGeophysical Research Letters, 2017
AbstractWe present a new technique for mapping the grounding line of Antarctic ice shelves using a combination of CryoSat‐2 standard and swath elevation data. Our method is based on detecting the tidal signal in pseudo crossovers and is tested on the Siple Coast region of West Antarctica.

Satellite radar altimetry aids seafloor mapping

open access: yesEos, Transactions American Geophysical Union, 1991
The connection between gravity and oceanic water depth was realized more than a century ago. In 1859, J. H. Pratt derived a formula relating anomalous vertical deflection and sea level height on the coast of India to the depth of the adjacent Indian Ocean.

Multi-Satellite Altimeter Validation along the French Atlantic Coast in the Southern Bay of Biscay from ERS-2 to SARAL

open access: yesRemote Sensing, 2018
Monitoring changes in coastal sea levels is necessary given the impacts of climate change. Information on the sea level and its changes are important parameters in connection to climate change processes.

Effects of Interferometric Radar Altimeter Errors on Marine Gravity Field Inversion

open access: yesSensors, 2020
The traditional altimetry satellite, which is based on pulse-limited radar altimeter, only measures ocean surface heights along tracks; hence, leads to poorer accuracy in the east component of the vertical deflections compared to the north component ...
