Improving Digital Mapping of Soil Organic Carbon and Total Nitrogen Through Integration of Sentinel‐1 Backscatter, InSAR Coherence, and Sentinel‐3 OLCI/SLSTR Observations

Land Degradation &Development, EarlyView.
ABSTRACT The potential of optical satellites for the spatial prediction of soil organic carbon (SOC) and total nitrogen (STN) has long been recognized. Owing to their balanced spatial–temporal resolution, multisource observational capabilities, and unprecedented availability of free data, Sentinel satellites offer unique opportunities for mapping soil ...

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

MSWD: A Hybrid Machine‐Learning Framework for Slant Wet Delay Modeling

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI) are limited by direction‐dependent tropospheric delays, with slant wet delay (SWD) being the most variable component and a major error source.

Interseismic Creep Along the Enriquillo–Plantain Garden Fault, Haiti, Estimated From InSAR

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Enriquillo–Plantain Garden fault zone (EPGFZ) is a major left‐lateral strike‐slip fault in southern Haiti hosting several recent destructive earthquakes, including the 2021 MW 7.1 Nippes event with primary thrust‐slip. To investigate how strain is accommodated in the vicinity of the 2021 event, we analyzed Sentinel‐1 interferometric ...

An interferometric technique for synthetic aperture ground-penetrating radar [PDF]

IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002
Many synthetic aperture radar (SAR) algorithms for ground-penetrating radar involve making measurements along a single path and using the collected data to form a two-dimensional image of the scattering object. In the calculation of these images, certain assumptions are made about the scattering objects; mainly, that the reflections are occurring ...

Consideration on Singular-Point Generating Mechanisms by Analyzing the Effect of Phase-and-Polarization Optimization in PolInSAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
We elucidate the generation mechanisms of singular points (SPs) by investigating the relationship between the phase distortion and the polarization-state changes in polarimetric interferometric synthetic aperture radar (PolInSAR). We find that there is a

Detecting peat‐like behaviour areas using European Ground Motion Service data

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
This study presents a scalable approach for detecting peat‐like behaviour areas (PBAs) using open‐access InSAR time series from the European Ground Motion Service. The method integrates unsupervised principal component analysis (PCA) and k‐means clustering to complement optical mapping and reveal peat‐like dynamics, supporting improved peatland ...
