Relative performance of future altimeter systems and tide gauges in constraining a model of North Sea high-frequency barotropic dynamics

, 2006
14 pages, 13 figures, 1 tableWe evaluate in this paper the ability of several altimeter systems, considered separately as well as together with tide gauges, to control the time evolution of a barotropic model of the North Sea shelf.

Multi-Source Satellite Altimetry for Monitoring Storm Wave Footprints in the English Channel’s Coastal Areas

Remote Sensing
Climate wave data, derived from significant wave height (SWH) altimetry, provide accurate information towards nearshore and coastal areas. Their use is crucial to enhance our capabilities of observing, understanding, and forecasting storm waves, even in ...

Altimeter Calibrations in the Preliminary Four Years’ Operation of Wanshan Calibration Site

Remote Sensing
In order to accomplish the calibration and validation (Cal/Val) of altimeters, the Wanshan calibration site (WSCS) has been used as a calibration site for satellite altimeters since its completion in August 2019. In this paper, we introduced the WSCS and

First In-Orbit Validation of Interferometric GNSS-R Altimetry: Mission Overview and Initial Results

Remote Sensing
Sea surface height (SSH) serves as a fundamental geophysical parameter in oceanographic research. In 2023, China successfully launched the world’s first spaceborne interferometric GNSS-R (iGNSS-R) altimeter, which features dual-frequency multi-beam ...

Airborne radar altimeter return waveform computations

, 2009
Radar altimeter experiments have shown the need for expanding the downward-looking, single-beam system into a multiple beam radar altimeter employing off-nadir altimetry so that information from a wider swath can be obtained from a single overflight ...

GNSS-R altimeter based on Doppler multi-looking

, 2014
Measuring ocean mesoscale variability is one of the main objectives of next generation satellite altimeters. Current radar altimeters make observations only at the nadir sub-satellite ground track, which is not sufficient to sample the ocean surface with
