The accuracy and applications of satellite altimetry [PDF]

Geophysical Journal International, 1995
Summary The recently launched TOPEX/POSEIDON altimeter mission is achieving an unprecedented accuracy in the measurement of the absolute sea-level, demonstrating that satellite radar altimetry has evolved into one of the fundamental instruments for providing synoptic observations of the global oceans with a temporal sampling of a few days to a month ...

An Action Plan Towards Fiducial Reference Measurements for Satellite Altimetry

Remote Sensing, 2019
Satellite altimeters have been producing, as of 1992, an amazing and historic record of sea level changes. As Europe moves into full operational altimetry, it has become imperative that the quality of these monitoring signals with their uncertainties ...

Analysis of Precise Orbit Determination for the HY2D Satellite Using Onboard GPS/BDS Observations

Remote Sensing, 2022
High-precision orbits of Low Earth Orbit (LEO) satellites are essential for many scientific applications, such as assessing the change in current global mean sea level, estimating the coefficients of gravity field, and so on.

Arctic Sea-Ice Surface Elevation Distribution from NASA’s Operation IceBridge ATM Data

Remote Sensing, 2022
In this paper, we characterize the sea-ice elevation distribution by using NASA’s Operation IceBridge (OIB) Airborne Topographic Mapper (ATM) L1B data over the Arctic Ocean during 94 Spring campaigns between 2009 and 2019.

MESI: A Multiparameter Eddy Significance Index

Earth and Space Science, 2023
In this study, we introduce the Multiparameter Eddy Significance Index (MESI) for use in conjunction with mesoscale eddy tracking to estimate the impact of mesoscale eddies on the upper ocean and marine ecosystems.

ICESAT-2 LASER ALTIMETRY DATA-GUIDED HIGH-ACCURACY POSITIONING OF SATELLITE STEREO IMAGES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Positioning accuracy is a key indicator that restricts the accuracy of satellite image mapping. Laser altimetry acquires surface height in decimeters or higher accuracy, providing high-accuracy topographic information for satellite photogrammetry.

Eddy Dynamics From Satellite Altimetry [PDF]

Oceanography, 2010
Most of the kinetic energy of ocean circulation is contained in ubiquitous mesoscale eddies. Their prominent signatures in sea surface height have rendered satellite altimetry highly effective in observing global ocean eddies. Our knowledge of ocean eddy dynamics has grown by leaps and bounds since the advent of satellite altimetry in the early 1980s ...
