Modeling the GNSS Rural Radio Channel: Wave Propagation Effects caused by Trees and Alleys [PDF]
, 2009 Among the various physical influencing factors with the potential to degrade the overall performance of a global navigation satellite system (GNSS), the behavior of the radio wave propagation channel occupies doubtlessly a central role.

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.

Ecohydrology, Volume 19, Issue 7, October/November 2026.ABSTRACT Sea level rise is causing the rapid conversion of upland habitats to salt marshes in low‐sloping areas due to increasing groundwater salinity and soil saturation. Despite this being a widespread phenomenon, questions remain about the factors shaping groundwater hydrology and salinity in these transitioning systems, particularly in the US ...

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.Freeze–thaw processes, moisture, and sediment properties control riverbank erosion in boreal–subarctic rivers. Field measurements, geotechnical analyses and monitoring reveal continuous, seasonally driven erosion, while climate projections indicate reduced freezing, potentially increasing erosion risk under warming conditions.

A Data‐Driven Review of Geoscience Research Evolution Using SciBERT‐Based Topic and Network Analysis
Geoscience Data Journal, Volume 13, Issue 4, October 2026.This review synthesises the evolution of global geoscience research from 2004 to 2023 using large‐scale bibliometric evidence. By combining keyword co‐occurrence network analysis with SciBERT‐based topic modelling, it identifies major paradigm transitions from geology‐centred research to climate‐focused studies and recent data‐ and AI‐driven ...
