Use of Tropospheric Delay in GNSS-Based Climate Monitoring—A Review

Remote Sensing
The troposphere is a key component of the Earth’s climate system, modulating weather patterns and global temperatures through intricate interactions between water vapor, atmospheric pressure, and temperature.

Spatial Interpolation of GNSS Troposphere Wet Delay by a Newly Designed Artificial Neural Network Model

Applied Sciences, 2019
Global Navigation Satellite System (GNSS) signals arrive at the Earth in a nonlinear and slightly curved way due to the refraction effect caused by the troposphere. The troposphere delay of the GNSS signal consists of hydrostatic and wet parts.

Permafrost Detachment Slides: A Distinct High‐Magnitude Permafrost Mass Wasting Process

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Warming permafrost is destabilizing landscapes, intensifying thaw‐driven mass wasting and giving rise to novel landslide forms. We characterize two recent (2017 and 2018), deep‐seated translational failures that we term Permafrost Detachment Slides (PDSs), which rapidly translocated 4.5 and 18 × 106 m3 of frozen material into downstream ...

Wave Signals From Rapidly Intensifying Typhoons Mark Vortex Adjustment Rather Than Robust Ionospheric Coupling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Rapidly intensifying typhoons can generate atmospheric waves, but nearby neutral‐atmosphere and ionospheric anomalies need not form a robust cross‐layer coupling chain. We examine 75 western North Pacific rapid‐intensification events during 2018–2023.

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.

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Drivers of Precision Agriculture Adoption in Italian Viticulture

Applied Economic Perspectives and Policy, Volume 48, Issue 4, Page 1258-1271, September 2026.
ABSTRACT This study examines the main drivers influencing the adoption of two types of precision farming technologies in the viticultural sector: Decision Support Systems (DSSs) and Variable Rate Technologies (VRTs). We apply a partial proportional odds model and find that socio‐demographic characteristics are not significant determinants of adoption ...
