High-Rate Altimetry in SNR-Based GNSS-R: Proof-of-Concept of a Synthetic Vertical Array
(2021-01-01)
Global Navigation Satellite System Reflectometry (GNSS-R) has emerged as a promising remote sensing technique for coastal sea level monitoring. GNSS-R based on signal-to-noise ratio (SNR) observations employs a single ...
Improved Sea Surface Height from Satellite Altimetry in Coastal Zones: A Case Study in Southern Patagonia
(Institute of Electrical and Electronics Engineers, 2017-08)
High-resolution 20-Hz Jason-2 satellite altimetry data obtained from crossing tracks numbered 52 and 189 in San Matias Gulf, Argentina, are compared with a 22-month-long time series of sea level measured by a bottom pressure ...
Validation of satellite altimetry by kinematic GNSS in central East Antarctica
(Copernicus Group, 2017-05)
Ice-surface elevation profiles of more than 30 000 km in total length are derived from kinematic GNSS (GPS and the Russian GLONASS) observations on sledge convoy vehicles along traverses between Vostok Station and the East ...
Malvinas Current variability from Argo floats and satellite altimetry
(Blackwell Publishing Ltd, 2016-07)
The Malvinas Current (MC) is an offshoot of the Antarctic Circumpolar Current (ACC). Downstream of Drake Passage, the northern fronts of the ACC veer northward, cross over the North Scotia Ridge (NSR) and the Malvinas ...
Coastal applications from nadir altimetry: Example of the X-TRACK regional products
(Elsevier, 2017-02)
In the coastal ocean zones, satellite altimetry data processing and interpretation poses specific difficulties, due to the interaction of the radar signal with land topography, inaccuracies in some of the geophysical ...
A comparison of the annual cycle of sea level in coastal areas from gridded satellite altimetry and tide gauges
(Elsevier, 2015-01)
In this work we compare the annual component of sea level variations derived from 478 worldwide- distributed tide gauges with the annual component computed from a weekly gridded multi-mission altimeter product. Gridded ...
Volume Transport Variability on the Northern Argentine Continental Shelf from In Situ and Satellite Altimetry Data
(Blackwell Publishing, 2021-02)
Direct current observations and satellite altimetry data over the northern portion of the Argentine continental shelf are used to produce an 11-month long hourly time series and a 25-year long daily time series of along-shore ...
Airborne laser altimetry survey of Glaciar Tyndall, Patagonia
(ELSEVIER SCIENCE BV, 2007-10)
The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November
of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin ...
Coastal currents in the Eastern Gulf of Tehuantepec from coastal altimetry
(Advances in Space Research, 2018-06-02)
we study the seasonal and interannual variability of the coastal currents along the eastern shelf of the Gulf of Tehuantepec. We use sea level from coastal altimetry distributed by the Centre de Topographie des Oceans et ...
