Lakes Studies from Satellite Altimetry
2010Accurate and continuous monitoring of lakes and inland seas has been possible since 1993 thanks to the success of satellite altimetry missions: TOPEX/POSEIDON (T/P), GFO, JASON-1, and ENVISAT. Global processing of the data of these satellites can provide time series of lake surface heights over the entire Earth at different temporal and spatial scales ...

Satellite Altimetry Applications in the Caspian Sea
2010The Caspian Sea is the largest continental water body on the Earth. Owing to its size and geographical location, the sea is truly a large-scale climatic and ecological indicator. One of the most important parameters of the state of the Caspian Sea is significant interannual sea level changes that puzzle the scientists of many countries.

Satellite Altimetry - An Introduction
1981The altimetry papers presented at the symposium show that the basic hypotheses underlying the measurement of sea surface topography have considerable merit, but that much work in both science and spacecraft technology remains to be done before such measurements become routine.

What are the limitations of satellite altimetry?
The Leading Edge, 1998Radar altimeter measurements of the marine geoid collected during the Seasat altimeter mission gave geophysicists hope of uncovering the gravity field over all the ocean basins. However, because of insufficient track density, it has taken 16 years for the full potential of the satellite altimeter to be realized.

Ice Sheet And Satellite Altimetry
Surveys in Geophysics, 2001Since 1991, the altimeters of the ERS European Satellites allow the observation of 80% of the Antarctica ice sheet and the whole Greenland ice sheet: They thus offer for the first time a unique vision of polar ice caps. Indeed, surface topography is an essential data thanks to its capacity to highlight the physical processes which control the surface ...

Geophysical Applications of Satellite Altimetry
Reviews of Geophysics, 1991Publications related to geophysical applications of Seasat and Geosat altimetry are reviewed for the period 1987-1990. Problems discussed include geoid and gravity errors, regional geoid heights and gravity anomalies, local gravity field/flexure, plate tectonics, and gridded geoid heights/gravity anomalies.

The Marine Geoid and Satellite Altimetry
2010The marine geoid defines the hydrostatic equilibrium shape that sea level would take in the absence of tides, currents and winds. The geoid is not directly observable, but its height above a reference ellipsoid may be calculated from a model of the Earth’s gravity field.

Spectral Windows for Satellite Altimetry
2016A satellite altimeter’s waveform is a power spectral density (PSD) estimate obtained from discrete Fourier transforms (DFTs) applied to time series produced by the instrument’s analog-to-digital converter (ADC). All altimeters apply a DFT to the digital sample sequence obtained from each pulse echo to synthesize pulse compression; the PSD of the echo ...

Geodetic Application of Satellite Altimetry
2003Satellite altimetry has developed to an operational remote sensing technique with important applications to many geosciences. In the present paper we consider in particular geodetic applications of satellite altimetry. It is shown that this space technique not only allows mapping and monitoring a major part of the Earth surface, but also did contribute
