Dataset of Coastline Positions for Sandy Beaches of England and Wales Derived Using Remote Sensing

open access: yesGeoscience Data Journal, Volume 13, Issue 4, October 2026.
Two decades (1999–2020) of annual coastline position dataset were generated using COASTSAT toolkit for sandy beaches of England and Wales. The dataset consists of annual coastline position coordinates in the format of GeoJSON and Tabular files. ABSTRACT This article presents a dataset of coastline positions, comprising annual sandy coastline detections

Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 778-803, October/December 2026.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

A new vertical reduction model for enhancing the interpolation accuracy of VMF1/VMF3 tropospheric delay products [PDF]

open access: yesGeoscientific Model Development
Grid-wise Vienna Mapping Functions 1 (VMF1) and Vienna Mapping Functions 3 (VMF3) tropospheric products are widely used to interpolate the a priori zenith hydrostatic delay (ZHD) and zenith wet delay (ZWD) over GNSS (Global Navigation Satellite Systems ...

Ionospheric Scintillation Induced by Hot Flow Anomalies via Particle Precipitation

open access: yesAGU Advances, Volume 7, Issue 7, October 2026.
Abstract Ionospheric scintillation disrupts trans‐ionospheric radio signals and represents significant challenges for critical communication and navigation systems. Here we document that hot flow anomalies (HFAs), transient disturbances formed near Earth's bow shock, can contribute to scintillation near the cusp.

Impact of Two Radio Occultation Constellations on Numerical Weather Prediction: Polar‐Orbits Only and Mixed Polar‐Equatorial Orbits

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study explores the relative impact of two orbital configurations for Global Navigation Satellite System radio occultation (RO) observations in numerical weather prediction using observing system simulation experiments (OSSE). Three experiments are carried out: a Control experiment with no RO observations and two experiments with 14,000 RO

Coupled Thermosphere–Ionosphere Dynamics During the 17 January 2013 Storm: GITM–TIDAS Comparison With Millstone Hill ISR Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This article analyzes a weak geomagnetic storm on January 17–18, 2013, using a first‐principles model (Global Ionosphere Thermosphere Model (GITM) with an empirical assimilative ionospheric model (TIDAS), evaluated against observations in the form of Millstone Hill (MH) incoherent scatter radar (ISR) altitude profiles and global navigation ...

Microgravity Measurements Spanning 2019–2022 Indicate No Change in Magma Supply or Storage During Kīlauea's Reawakening

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract After more than 2 years of quiescence following its major 2018 flank lava effusion and summit caldera collapse, Kīlauea, Hawaiʻi, returned to frequent eruptive activity in late 2020. Microgravity measurements from the summit region in 2019 and 2022 span this reawakening and indicate a gravity increase of up to hundreds of microgals near the ...
