Common Sensor Platform Project

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract EarthScope Consortium's Common Sensor Platform (CSP) project is a unified, modular, and scalable design approach for geophysical instrumentation deployments. Developed through cross disciplinary collaboration of National Science Foundation's GAGE and SAGE facilities, the platform outlines core station subsystems that have the flexibility to be

A Variational Approach for Modeling the Inductive Response of Earth's Mantle to Time‐Varying External Geomagnetic Source

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract A mathematical and numerical framework is developed for modeling Earth's magnetic field and optimizing the trajectory of the whole system using geomagnetic observations. The conventional approach is adopted to model Earth's magnetic field in the source‐free region via the Gauss coefficient, for which the fast dynamical component for the mantle‐

Equatorial Ionospheric VTEC Perturbations During the 21 June 2020 Solar Eclipse

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The annular solar eclipse of 21 June 2020, provided a valuable opportunity to examine the ionospheric response to celestial events. This study analyzes variations in Vertical Total electron content (VTEC) over the equatorial region using data from the UQRG Global Ionospheric Map (GIM), ground‐based GPS‐TEC measurements, and equatorial ...

Evidence for Subtropical Dynamical Changes in Reunion Ozone Trends (1998–2021)

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract We provide trend estimates for total, stratospheric, and tropospheric ozone columns over Reunion (21.1°S, 55.5°E) from 1998 to 2021, using only Système d’Analyze par Observation Zénithale and Southern Hemisphere Additional OZonesonde observations.

Analysis of South Atlantic Anomaly Influence on Low‐Earth Orbit Lightning Observations

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The low‐Earth orbit Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) instruments, spanning 1995–2023, have spatiotemporal patterns within their metadata that are consistent with the South Atlantic Anomaly (SAA). While the SAA had a known influence on these instruments, this study details new variability and impacts.

Seasonally Dependent Formation of Sulfates in the Basque Lakes, British Columbia, as Analogous to “Cold and Wet” and “Warm and Wet” Mars

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Saline lakes are expected to have been extensively present on ancient Mars, particularly as the planet dried or cooled. Such lakes likely deposited sulfate salts, as these salts have been widely identified from orbital and in situ Mars data. However, the relationship between martian sulfates and the environmental conditions that formed them ...

Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...

Abiotic Siliceous Botryoids on Iron Oxyhydroxide Filaments From Hydrothermal Vents in the Southwest Indian Ocean

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Fe‐oxidizing microorganisms in deep‐sea hydrothermal vent environments are often used as analogs for primordial life on Earth. In fact, Earth's oldest purported microfossils are preserved as hematite filaments in a jasper rock dated between 4,160 and 4,280 million years and are thought to have originated in a seafloor hydrothermal environment.

Viscosity‐Driven Dynamics of the Midnight Temperature Maximum in the Low‐Latitude Thermosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract This paper investigates the impact of viscosity on the dynamics of the Midnight Temperature Maximum (MTM) in the low‐latitude thermosphere. Our study utilizes simulations to examine how varying levels of viscosity influence neutral temperature patterns and horizontal wind behaviors, which, in turn, drive the MTM characterized by peak neutral ...
