Antarctic Ice Sheet and Radar Altimetry: A Review [PDF]
Remote Sensing, 2009 Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSatellite altimetry has revolutionized river monitoring, particularly for hydrologists working on river flow monitoring in sparsely or ungauged areas. Despite this, there is a lack of a comprehensive evaluation of radar and LiDAR altimeters with varying ...

Evaluation of historic and operational satellite radar altimetry missions for constructing consistent long-term lake water level records [PDF]
Hydrology and Earth System Sciences, 2021 A total of 13 satellite missions have been launched since 1985, with different types of radar altimeters on board. This study intends to make a comprehensive evaluation of historic and currently operational satellite radar altimetry missions for lake ...

Joint analysis of coastal altimetry and high-frequency (HF) radar data: observability of seasonal and mesoscale ocean dynamics in the Bay of Biscay [PDF]
Ocean Science, 2018 Land-based coastal high-frequency (HF) radar systems provide operational measurements of coastal surface currents (within 1–3 m depth) with high spatial (300 m–10 km) and temporal ( ≤ 1 h) sampling resolutions, while the ...

Satellite radar altimetry for monitoring small rivers and lakes in Indonesia [PDF]
Hydrology and Earth System Sciences, 2015 Remote sensing and satellite geodetic observations are capable of hydrologic monitoring of freshwater resources. Although satellite radar altimetry has been used in monitoring water level or discharge, its use is often limited to monitoring large rivers (

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).
