Beyond Exact Repeat Missions: Embracing Geodetic Altimetry for Inland Water Monitoring and Modeling

Journal of Remote Sensing
Satellite radar altimetry has become an essential tool for hydrological research over the past 2 decades. Unlike imagery that quantifies the water dynamics from the horizontal dimension, altimetry observations deliver vertical information, which is ...

ALTIMETRY BY CASSINI RADAR: PROCESSING AND SIMULATION [PDF]

, 2009
The Cassini mission, that is a joint NASA/ESA/ASI effort, has recently offered the unique possibility of exploring Titan, the largest moon of Saturn, that is the only satellite in the solar system to host an appreciable atmosphere, which unfortunately made the surface below very difficult to be observed from the Earth with optical instruments. In fact,

Lake studies from satellite radar altimetry

Comptes Rendus. Géoscience, 2006
For more than 10 years, satellite radar altimetry has been a successful technique for monitoring the variation in elevation of continental surface water, such as inland seas, lakes, rivers, and more recently wetland zones. The surface water level is measured within a terrestrial reference frame with a repeatability varying from 10 ...

Along‐Track Marine Geoid Resolution Enhancement With SWOT

Earth and Space Science
Satellite altimetry has been the major data source for marine geoid determination·and gravity recovery in recent decades. In general, altimetry‐derived geoid and gravity anomaly models are typically released with a 1' × 1' gridding interval.

Slope Correction for Ocean SAR Altimetry

Earth and Space Science
Since the 2010 launch of Cryosat‐2, a new generation of altimeters, referred to as SAR altimetry, has emerged and partially replaced the previous conventional altimeters known as Low Resolution Mode (LRM) altimetry.
