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

Tropical Pacific spatial trend patterns in observed sea level: internal variability and/or anthropogenic signature? [PDF]
, 2012 In this study we focus on the sea level trend pattern observed by satellite altimetry in the tropical Pacific over the 1993–2009 time span (i.e. 17 yr).

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

Comparison between Eulerian diagnostics and finite-size Lyapunov exponents computed from altimetry in the Algerian basin [PDF]
, 2008 Transport and mixing properties of surface currents can be detected from altimetric data by both Eulerian and Lagrangian diagnostics. In contrast with Eulerian diagnostics, Lagrangian tools like the local Lyapunov exponents have the advantage of ...

Comparison of Integrating GF-7 and ICESat-2 Laser Altimetry Data with High-resolution Stereo Images for Stereo Mapping [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesCurrently, two types of satellite laser altimetry systems are in operation: the full waveform linear system and the single-photon-counting system, which exhibit significant differences in both data format and processing methodologies.

Jets and Topography: Jet Transitions and the Impact on Transport in the Antarctic Circumpolar Current [PDF]
, 2012 The Southern Ocean’s Antarctic Circumpolar Current (ACC) naturally lends itself to interpretations using a zonally averaged framework. Yet, navigation around steep and complicated bathymetric obstacles suggests that local dynamics may be far removed from

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

Sentinel-3A SRAL Global Statistical Assessment and Cross-Calibration with Jason-3
Remote Sensing, 2019 The Sentinel-3A satellite, equipped with Synthetic Aperture Radar (SAR) Altimeter (SRAL) instrument to derive sea surface height, significant wave height and surface wind speed over the global ocean, was launched on 16 February 2016.

Geophysical Research Letters, 2023 The fastest projected rates of sea level rise appear in models which include “the marine ice cliff instability (MICI),” a hypothesized but mostly unobserved process defined by rapid fracture and wastage of terminal ice cliffs that outpaces viscous ...

Validation of airborne and satellite altimetry data by Arctic Trucks citizen science
GEUS Bulletin, 2021 The elevation of ice sheets changes due to climate change, and satellite altimetry is the preferred tool for measuring ice sheet-wide height changes. In situ validation is needed to ensure the quality of the observed elevation changes, but the cost often
