Altimetry for the future: Building on 25 years of progress [PDF]

Advances in Space Research, 2021
In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more ...

Advances in GNSS-R altimetry

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Since the nadir 1-second altimetry precision was first estimated to be of 56 cm when the PARIS concept was developed back in 1993 (it was assumed the interferometric processing of GPS P-code signals and a 4×4 m×m receiving antenna at 700 km orbital altitude) [1], many detailed analyses and experiments have been conducted leading to far more optimistic ...

Airborne Lidar Altimetry in support of Radar Altimetry

2016
In a series of experiments between 2011 and 2016, in the Gulf of Mexico and off the coast of California, directional wave field and the sea surface height anomaly (SSHA) measurements were collected by the Scripps Modular Aerial Sensing System (MASS) waveform scanning lidar.

Basic Radar Altimetry Toolbox

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
A NEW SET OF TOOLS FOR ALL ALTIMETRY USERS The field of satellite radar altimetry has matured to a point where it is now time to encourage a multimission approach and conceive an "all-altimeter" toolbox including a tutorial. Such an integrated approach and view is vital not only for assessing the current status of what offers altimeter products but ...

SSALTO/DUACS and operational altimetry

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
The SSALTO/DUACS multiple altimeter processing system provides MERCATOR, GODAE, and climate forecasting centers with directly usable, high quality near real time altimeter data. Commercial applications for the fishery and offshore industries are also developed.

Satellite altimetry

Reviews of Geophysics, 1983
During the past four years satellite altimetry activities have been primarily concerned with analyses of the GEOS‐3 and Seasat data sets, and the justification and design of next generation altimetric missions and associated instrumentation.Since the last IUGG Quadrennial review of satellite altimetry [Stanley, 1979a], considerable documentation of ...

Satellite altimetry

Reviews of Geophysics, 1979
Since the last national report to the sixteenth General Assembly, research activities in the development of appropriate techniques and the direct application of altimeter data have moved rapidly from the launch of the SKYLAB S‐193 Experiment in 1973 through the GEOS‐3 launched in June 1975 to the SEASAT‐1 launched in June 1978.

A super-resolution laser altimetry concept

SPIE Proceedings, 2011
A super-resolution laser altimetry technique has been proposed to provide improved lidar altimetry from Cloud Aerosol Lidar and Infrared Pathfinder Satellite Observation(CALIPSO) lidar data, and it is applicable to other similar atmospheric profiling lidar with low-pass filters.

Altimetry-Gravimetry Problem: An Example

1990
The 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.

Spaceborne radar altimetry

Proceedings of SOUTHEASTCON '96, 2002
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
