GNSS Profile from the Greenland Korth Expeditions in the Context of Satellite Data

open access: yesApplied Sciences, 2021
Over the last two decades, a small group of researchers repeatedly crossed the Greenland interior skiing along a 700-km long route from east to west, acquiring precise GNSS measurements at exactly the same locations.

Definition of ICESat Selection Criteria for their Use as Height References for TanDEM-X [PDF]

open access: yes, 2010
The TanDEM X satellite synthetic aperture radar (SAR) mission has the goal to deliver a high-precision global digital elevation model (DEM). The X band SAR interferometry (InSAR)-derived DEMs contain absolute and relative height errors that have to be ...

Reconsidering the Relationship Between Gulf Stream Transport and Dynamic Sea Level at U.S. East Coast

open access: yesGeophysical Research Letters, 2023
The relationship between Gulf Stream (GS) transport and coastal sea level is investigated using monthly GS transport between 1993 and 2019 at Florida Straits and 10 altimeter tracks. The results show that GS transport decorrelates quickly along its path,

Combining in situ measurements and altimetry to estimate volume, heat and salt transport variability through the Faroe–Shetland Channel [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.

Comparison of Integrating GF-7 and ICESat-2 Laser Altimetry Data with High-resolution Stereo Images for Stereo Mapping [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Currently, two types of satellite laser altimetry systems are in operation: the full waveform linear system and the single-photon-counting system, which exhibit significant differences in both data format and processing methodologies.

Observing and Modelling the HighWater Level from Satellite Radar Altimetry During Tropical Cyclones [PDF]

open access: yes, 2015
This paper investigates the capability of observing tropical cyclones using satellite radar altimetry. Two representative cyclones Yasi (February 2011) and Larry (March 2006) in the northeast Australian coastal area are selected based also on available ...

On the resolutions of ocean altimetry maps [PDF]

open access: yesOcean Science, 2019
Abstract. The DUACS system produces sea level global and regional maps that serve oceanographic applications, climate forecasting centers, geophysics and biology communities. These maps are constructed from optimal interpolation of altimeter observations and are provided on a global 1/4° × 1/4° (longitude × latitude) and daily grid resolution framework
