Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Estimating Zenith Tropospheric Delay Based on GPT2w Model

IEEE Access, 2019
To precisely and conveniently estimate zenith tropospheric delay (ZTD), troposphere refractivity is deduced through global pressure and temperature 2w (GPT2w) model and surface meteorology devices, ZTD is estimated based on integration of refractivity in

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

GNSS meteorologija i istraživanje parametara troposfere : GNSS meteorology and tropospheric paramteres investigation

, 2015
Troposfera igra značajnu ulogu za geodetsku zajednicu, što se prije svega ogleda u njenom utjecaju na GNSS opažanja. Istovremeno, u troposferi se dešavaju skoro sve hirdometeorološke pojave, koje utječu na našu svakodnevnicu.

Gravity Wave Influences on MSTID Climatology Over CONUS: WACCM‐X Year‐Long Simulation and GNSS Long‐Term Observation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Can Android Smartphones Contribute to GNSS Meteorology?

The Global Navigation Satellite System (GNSS) is an essential tool for tropospheric monitoring. Currently, GNSS meteorology relies mainly on the data collected from geodetic-grade receivers of global or regional networks. However, such stations are costly, and thus cannot be densely deployed, especially in less developed regions.
