Altimetry-Gravimetry Problem: An Example
1990The topographic surface of the sea can be determined by subtracting the geoid from the geometric height of the stationary sea surface. This latter can be obtained from altimetry measurements; the former can be derived from marine gravity measurements, treated in the form of gravity disturbances.

A next generation compact, Ku-band, pulse compression radar altimeter (RA) measures sea surface topography to a few centimeters accuracy and provides scientific data for assessing ocean circulation, mean sea-level change and other ocean features. The integrated RA is comprised of a basic altimeter, a water vapor radiometer (WVR) for correcting RA range

Altimetry in the Cassini Mission
1995 International Geoscience and Remote Sensing Symposium, IGARSS '95. Quantitative Remote Sensing for Science and Applications, 2002The main purpose of the Cassini Mission is the investigation of the geomorphologic structure of Titan, the most interesting moon of the Saturnian system. Titan is completely covered by a dense atmosphere that prevents optical observation. A spacecraft will be launched toward Saturn in 1997. The spacecraft will be equipped with microwave instruments.

ICESat Full-Waveform Altimetry Compared to Airborne Laser Scanning Altimetry Over The Netherlands
IEEE Transactions on Geoscience and Remote Sensing, 2009Since 2003, the full-waveform laser altimetry system onboard NASA's Ice, Cloud and land Elevation Satellite (ICESat) has acquired a worldwide elevation database. ICESat data are widely applied for change detection of ice sheet mass balance, forest structure estimation, and digital terrain model generation of remote areas.

Sea Modeling by Microwave Altimetry
2006In this note the applications of altimeter data to the monitoring of the sea surface height and, in particular, to the evaluation of large-scale oceanic currents are reviewed. The general problem of the altimeter measurement, with a special reference to the TOPEX/POSEIDON mission, is discussed.

NOTES ON TERRESTRIAL ALTIMETRY
Survey Review, 1961AbstractThe determination of height differences from readings of the atmospheric pressure involves the conversion of pressure readings into linear units, with temperature as the principal variable, and the application of corrections for the pressure change with time and with distance (two components) from the initial base reading.
