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.

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

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

Sea state bias in altimeter sea level estimates determined by combining wave model and satellite data [PDF]
, 2010 This study documents a method for increasing the precision of satellite-derived sea level measurements. Results are achieved using an enhanced three-dimensional (3-D) sea state bias (SSB) correction model derived from both Jason-1 altimeter ocean ...

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.

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

Satellite mapping of the Antarctic gravity field
Annals of Geophysics, 1999 The production and analysis of the Antarctic digital magnetic anomaly map will be greatly aided by complementary gravity data. They help to constrain thickness variations of the crust and related magnetic effects that may be used for correcting long ...
