Evaluation of selected methods for extracting digital terrain models from satellite born digital surface models in urban areas

, 2011
For the generation of 3D city models from satellite stereo imagery beyond the generation of digital surface models (DSM) from stereo data the next crucial step is the separation of urban 3D objects from ground.

APPLICABILITY OF 10Hz SATELLITE ALTIMETRY DATA TO THE ANTARCTIC MARGIN

, 1997
P(論文)Since the declassification of the Geosat Geodetic Mission (Geosat/GM), cross-track resolution of satellite altimeter profiles has improved remarkably. Consequently, the cross-track resolution somewhat exceeds the along-track resolution.

AltiMaP: altimetry mapping procedure for hydrography data [PDF]

Earth System Science Data
Satellite altimetry data are useful for monitoring water surface dynamics, evaluating and calibrating hydrodynamic models, and enhancing river-related variables through optimization or assimilation approaches.

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

Hidden Fine‐Scale Transport Pathways and Biological Connectivity Revealed by SWOT

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Oceanic currents redistribute nutrients, phytoplankton, and other biogenic materials, fundamentally shaping marine biodiversity and ecosystem functioning. Yet, the topology of fine‐scale material transport remains poorly resolved due to limitations in high‐resolution flow observations.

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]

, 2010
The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Large Drifter Experiment in the Western Mediterranean Sea Reveals Dynamical Versus Noise Contributions in SWOT‐KaRIn Sea Level

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The wide‐swath altimeter Surface Water and Ocean Topography (SWOT) provides unprecedented two‐dimensional sea‐level observations, whose ability to capture upper‐ocean dynamics requires assessment. The dynamically balanced signal and noise contributions in SWOT‐KaRIn Level‐3 (L3) sea level products are here originally quantified and contrasted ...

Distinct Vertical Structures of Global Eddy Heat and Salt Transports Revealed by Altimetry and Argo Observations

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Mesoscale eddies play a key role in redistributing oceanic heat and salt, yet their global three‐dimensional (3D) transport structures remain poorly understood. Here, we estimate global meridional eddy heat and salt transports in the upper 1,800 m from satellite altimeter and Argo observations, revealing distinct vertical structures. Eddy heat
