Liquid‐filled canyons on Titan [PDF]

open access: yesGeophysical Research Letters, 2016
In May 2013 the Cassini RADAR altimeter observed channels in Vid Flumina, a drainage network connected to Titan's second largest hydrocarbon sea, Ligeia Mare.

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]

open access: yes, 2017
A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Quantifying Surface‐Height Change Over a Periglacial Environment With ICESat‐2 Laser Altimetry

open access: yesEarth and Space Science, 2021
We use Ice, Cloud, and land Elevation Satellite 2 (ICESat‐2) laser altimetry crossovers and repeat tracks collected over the North Slope of Alaska to estimate ground surface‐height change due to the seasonal freezing and thawing of the active layer.

Improved Determination of Europa's Long‐Wavelength Topography Using Stellar Occultations

open access: yesEarth and Space Science, 2021
Europa Clipper will arrive at Jupiter at the end of this decade and will explore Europa through a series of flybys. One of its many goals is to characterize Europa's topography and global shape using the Europa Imaging System and Radar for Europa ...

Satellite altimetry and operational oceanography: from Jason-1 to SWOT [PDF]

open access: yesOcean Science
The development and evolution of satellite altimetry and operational oceanography are very closely linked. By providing all weather, global, and real-time observations of sea level, a key variable to constrain ocean analysis and forecasting systems ...

Eddy Dynamics From Satellite Altimetry [PDF]

open access: yesOceanography, 2010
Most of the kinetic energy of ocean circulation is contained in ubiquitous mesoscale eddies. Their prominent signatures in sea surface height have rendered satellite altimetry highly effective in observing global ocean eddies. Our knowledge of ocean eddy dynamics has grown by leaps and bounds since the advent of satellite altimetry in the early 1980s ...

Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]

open access: yes, 2010
Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform

Current state of art of satellite altimetry

open access: yesGeodesy and Cartography, 2017
One of the fundamental problems of modern geodesy is precise defi nition of the gravitational fi eld and its changes in time. This is essential in positioning and navigation, geophysics, geodynamics, oceanography and other sciences related to the climate

Relating Agulhas leakage to the Agulhas Current retroflection location [PDF]

open access: yes, 2009
The relation between the Agulhas Current retroflection location and the magnitude of Agulhas leakage, the transport of water from the Indian to the Atlantic Ocean, is investigated in a high-resolution numerical ocean model.

Data-Driven Calibration Algorithm and Pre-Launch Performance Simulations for the SWOT Mission

open access: yesRemote Sensing, 2022
The Surface Water and Ocean Topography (SWOT) mission will be affected by various sources of systematic errors, which are correlated in space and in time. Their amplitude before calibration might be as large as tens of centimeters, i.e., able to dominate
