Results from a magnetic survey and geomagnetic depth sounding in the post-eruption phase of the Barren Island volcano [PDF]
The Geological Survey of India conducted a magnetic survey and geological studies in 1993 around Barren Island in the Andaman Sea on board the RV Samudra Manthan. Five ocean bottom magnetometers were deployed by the Indian Institute of Geomagnetism as a part of this cruise. The Curie isotherm profiles prepared from the seasurface magnetic data indicate

WACCM‐X Simulation of the Atmosphere From 1950 Through 2024 at an Hourly Resolution
Abstract Modeling of the upper atmosphere, namely the thermosphere and ionosphere, is becoming important for applications such as orbital propagation (including satellite collision avoidance), radio propagation for communications, radar and position, navigation and timing.

Exploring Enceladus's Interior Structure Using Electromagnetic Induction
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

Abstract Total Electron Content (TEC) is influenced by local and global scale factors: localized effects causing fine‐grained differences in small areas, and global‐scale effects driving synchronized variations across all over the world. This underscores the necessity of modeling both global and local features for high‐performance TEC prediction.

How Does the Definition of a Geomagnetic Storm Affect the Contents of the Resulting Storm List?
Abstract A geomagnetic storm is a significant and prolonged disturbance of the Earth's magnetic field caused by an enhancement of the ring current. Storms are typically identified using magnetic field measurements from multiple ground‐based magnetometers, and the corresponding dates and times of multiple storms can be collated to form a storm list ...

Smartphone Carrier Phase TEC: A Study Across Ionospheric Spatio‐Temporal Scales
Abstract This study explores the potential of dual‐frequency smartphones as accessible tools for citizen science in ionospheric research. While prior work by Smith et al. (2024, https://doi.org/10.1038/s41586‐024‐08072‐x) demonstrated global ionospheric monitoring using aggregated pseudorange Total Electron Content (TEC) data from millions of Android ...

AMPERE Observations of the Asymmetry Toward Stronger Birkeland Currents in the Northern Hemisphere
Abstract We quantify the asymmetry between the Birkeland currents (also known as field‐aligned currents) in the Northern and Southern Hemispheres. We use data from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) in 2010–2024 inclusive for both hemispheres, compute the observed asymmetry, and then subtract the modeled

Joint inversion of satellite-detected tidal and magnetospheric signals constrains electrical conductivity and water content of the upper mantle and transition zone [PDF]
We present a new global electrical conductivity model of Earths mantle. The model was derived by using a novel methodology, which is based on inverting satellite magnetic field measurements from different sources simultaneously.
