River monitoring from satellite radar altimetry in the Zambezi River basin [PDF]

open access: yes, 2012
Satellite radar altimetry can be used to monitor surface water levels from space. While current and past altimetry missions were designed to study oceans, retracking the waveforms returned over land allows data to be retrieved for smaller water bodies or

Satellite Altimetry and Current-Meter Velocities in the Malvinas Current at 41°S: Comparisons and Modes of Variations [PDF]

open access: yes, 2017
Three year long current-meter arrays were deployed in the Malvinas Current at 418S below a satellite altimeter track at about 10 years intervals. Surface geostrophic velocities (SGV) derived from satel- lite altimetric data are compared with the in situ ...

Ocean Currents Reconstruction from a Combination of Altimeter and Ocean Colour Data: A Feasibility Study

open access: yesRemote Sensing, 2021
Measuring the ocean surface currents at high spatio-temporal resolutions is crucial for scientific and socio-economic applications. Since the early 1990s, the synoptic and global-scale monitoring of the ocean surface currents has been provided by ...

Eddy Dynamics From Satellite Altimetry [PDF]

open access: yesOceanography, 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 ...

Satellite altimetry and operational oceanography: from Jason-1 to SWOT [PDF]

open access: yesOcean Science
The development and evolution of satellite altimetry and operational oceanography are very closely linked. By providing all weather, global, and real-time observations of sea level, a key variable to constrain ocean analysis and forecasting systems ...

Impact of Ocean Domain Definition on Sea Level Budget

open access: yesRemote Sensing, 2021
Total sea level changes from space radar altimetry are mainly decomposed into two contributions of mass addition and volume expansion of oceans, measured by GRACE space gravimeter and Argo float array, respectively.

Combining in situ measurements and altimetry to estimate volume [PDF]

open access: yes, 2013
From 1994 to 2011, instruments measuring ocean currents (Acoustic Doppler Current Profilers; ADCPs) have been moored on a section crossing the Faroe–Shetland Channel.

Current state of art of satellite altimetry

open access: yesGeodesy and Cartography, 2017
One of the fundamental problems of modern geodesy is precise defi nition of the gravitational fi eld and its changes in time. This is essential in positioning and navigation, geophysics, geodynamics, oceanography and other sciences related to the climate

Quantifying Surface‐Height Change Over a Periglacial Environment With ICESat‐2 Laser Altimetry

open access: yesEarth and Space Science, 2021
We use Ice, Cloud, and land Elevation Satellite 2 (ICESat‐2) laser altimetry crossovers and repeat tracks collected over the North Slope of Alaska to estimate ground surface‐height change due to the seasonal freezing and thawing of the active layer.
