Quantifying Land–Sea Connectivity Through Remotely Sensed River Plumes
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Coastal ecosystems are highly influenced by riverine freshwater inputs, but the nature of these influences is dynamic and hard to characterize. Here we present a method that leverages remote sensing data of river plumes to quantify land–sea connectivity.

Analysis of Low-Oversampled Staggered SAR Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 The combination of SCan-On-REceive with continuous variation of the pulse repetition interval during transmission (staggered operation) is a viable option for the acquisition of high-resolution synthetic aperture radar (SAR) data over wide areas.

BridgeSAR: Measuring Bridge‐Water Clearance From Space Using SAR Multipath Signatures
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Bridge‐water clearance controls safe vessel passage and reflects local water‐level changes, but direct measurements are unavailable at many bridges. We present BridgeSAR, a geometry‐guided method that estimates clearance from multipath scattering stripes in synthetic aperture radar (SAR) amplitude images.

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.
