Comparison of GPS slant wet delays acquired by different techniques [PDF]

, 2012
This paper discusses the quality of slant wet delays (SWD) computed from GPS measurements. The SWDs are generally used as input data for GPS tomography, which allows the three-dimensional reconstruction of water vapour distribution in the atmosphere ...

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...

From pixel to mesh: accurate and straightforward 3D documentation of cultural heritage from the Cres/Lošinj archipelago [PDF]

, 2015
Most people like 3D visualizations. Whether it is in movies, holograms or games, 3D (literally) adds an extra dimension to conventional pictures. However, 3D data and their visualizations can also have scientic archaeological benets: they are crucial in ...

Stress Transfer From Slow Slip Events to Earthquake Swarms as a Cycle in the Southernmost Ryukyu Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Relatively Intense Daytime GNSS Amplitude Scintillations at Middle Latitude Linked With Multi‐Layered Strong Es Structures

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Intense Global Navigation Satellite System (GNSS) amplitude scintillations usually occur in nighttime at low latitudes due to ionospheric plasma bubble irregularities. During daytime at middle latitudes, previous studies found that the sporadic E (Es) layer could lead to GNSS amplitude scintillations, which however, is relatively weak, for ...

GNSS Meteorology in Luxembourg

, 2012
Atmospheric water vapour is a primary greenhouse gas and plays an important role in weather forecasting and climate monitoring. Global Navigation Satellite System (GNSS) signals experience a propagation delay, which is related to the amount of water vapour in the lower atmosphere.

Spatiotemporal Variations in the Interplate Slip Rate Around Kodiak Island, Alaska

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Monitoring spatiotemporal variations in the interplate slip rate during the interseismic period, such as transient strain release by slow slip events (SSEs), is crucial for characterizing the physical properties of faults. We analyze 10 years of Global Navigation Satellite System (GNSS) data in the region of Kodiak Island, Alaska.

Influence of Ionospheric Irregularities on GNSS Remote Sensing

Advances in Meteorology, 2015
We have used numerical simulation to study the effects of ionospheric irregularities on accuracy of global navigation satellite system (GNSS) measurements, using ionosphere-free (in atmospheric research) and geometry-free (in ionospheric research) dual ...

Electron density extrapolation above F2 peak by the linear Vary-Chap model supporting new Global Navigation Satellite Systems-LEO occultation missions [PDF]

, 2017
The new radio-occultation (RO) instrument on board the future EUMETSAT Polar System-Second Generation (EPS-SG) satellites, flying at a height of 820 km, is primarily focusing on neutral atmospheric profiling.
