Multisurface Retracker for Swath Processing of Interferometric Radar Altimetry [PDF]

IEEE Geoscience and Remote Sensing Letters, 2019
Swath mode processing of CryoSat-2 Synthetic Aperture Radar Interferometric (SARIn) mode has been used to monitor elevation of areas with complex topography such as over ice sheet and ice cap margins. Swath processing relies on an accurate measure of the angle of arrival of the measured echo and, therefore, requires custom strategies in order to ...

The Potential for Leveraging SWOT‐Mapped Uneven Water Surface Elevations to Enhance ICESat‐2–Derived Lake Levels

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Satellite altimetry is advantageous for measuring water surface elevations (WSE) globally. However, biases of time series can be caused by uneven water surfaces, as nadir pointing measurements are often collected at different locations across a lake.

Revealing Coastal Storm‐Wave Transformations From SWOT HR Observation: The English Channel Case Study

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.

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

, 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 ...

From Lotic to Lentic: SWOT Characterizes Seasonal Hydrodynamics in the Lake‐River Continuum

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The interface between rivers and lakes forms a unique hydraulic continuum, in which lotic and lentic regimes dynamically interact and transition between each other. A common expression of this lake‐river continuum (LARIC) is reservoir backwater, where water surface gradually rises from the reservoir pool upstream to the free‐flowing river ...

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

, 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 ...

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.

Coincident cloud observations by altimetry and radiometry [PDF]

, 2004
There are many different sensors that can be used for studies of clouds or rain. However, it is only with Envisat that a dual-frequency altimeter has been comanifested with a high-precision infra-red radiometer. This paper is the first to demonstrate the

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.
