A Graphical Model Approach for Efficient Geomagnetism-Pedometer Indoor Localization

, 2017
Geomagnetism is promising for indoor localization due to its pervasive presence, high signal stability and unnecessity of extra infrastructure support. It can be fused with a pedometer (step counter) to further improve accuracy. Traditional fusions based

Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...

Strong Westward Current Pulse at Auroral Latitudes Extending to Dawn‐Side Low‐Latitudes Due To Enhanced Density Within Kelvin‐Helmholtz Wave Vortex in Solar Wind

Geophysical Research Letters
A series of coronal mass ejections (CMEs) from the Sun, interacted with one another and formed a complex interplanetary‐CME (ICME) that impinged Earth's magnetosphere on 10 May 2024 and caused the strongest geomagnetic storm of the past two decades.

Satellite Traces: Ionogram Signatures of Bottom‐Side Upwelling Structures ‐ A Simulation Study

Geophysical Research Letters
Satellite Traces (STs) are the important ionogram signatures for the presence of upwellings in the bottom‐side ionosphere, which provide the necessary seed perturbation for the development of equatorial plasma bubbles (EPBs).

Metadata in geomagnetism : experiences of the World Data Centre for Geomagnetism, Edinburgh [PDF]

, 2011
Geomagnetic observatory data dates back more than 150 years. However, since the advent of digital recordings in the 1960s these data have become increasingly separated from their associated metadata.
