A Hierarchical Bayesian Model for the Global Holocene Geomagnetic Field
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract We present a hierarchical Bayesian model of the global geomagnetic field for the last 8,000 years. The model is built solely with thermoremanent records, which include archeomagnetic and volcanic data. Building upon previous work, this model includes fewer approximations and treats model hyperparameters as probabilistic variables.

Space Weather, Volume 24, Issue 5, May 2026.Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Modeling the geomagnetic field over Croatia
Geofizika, 2011 During the last years investigation of the geomagnetic field in Croatia has started and an effort to establish the geomagnetic observatory has been made. Based on the total field measured over the northern eastern part of Croatia, the suitable position for installing the geomagnetic observatory is proposed.

Statistics of the geomagnetic secular variation for the past 5Ma [PDF]
A new statistical model is proposed for the geomagnetic secular variation over the past 5Ma. Unlike previous models, the model makes use of statistical characteristics of the present day geomagnetic field.

What happens when the geomagnetic field reverses?
, 2012 During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...

Storm‐Time Dst Forecast: An Innovative Approach
Space Weather, Volume 24, Issue 5, May 2026.Abstract One of the most persistent challenges in the space weather field is predicting the storm‐time response of the geospace without knowing the predicted drivers in the solar wind. Here, a new pattern recognition algorithm is developed to predict storm‐time Dst index from 1 hr to ∼4.5 days into the future. Storm‐time Dst patterns (or reference Dst)

Geomagnetic ground survey in Slovakia for the 2007.5 epoch
Contributions to Geophysics and Geodesy, 2009 New geomagnetic ground survey was carried out in years 2006–2008. The survey was accomplished under fair geomagnetic-activity conditions during the minimum phase of a solar activity cycle No. 23. The measurements of the geomagnetic field

Initial geomagnetic field model from MAGSAT [PDF]
Magsat data from magnetically quiet days were used to derive a thirteenth degree and order spherical harmonic geomagnetic field model, MGST(3/80). The model utilized both scalar and vector data and fit that data with standard deviations of 8, 52, 55 and ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract On 20 January 2024, a deep‐focus earthquake (Mw 6.6, depth 607 km) struck near Tarauacá, Brazil, within the subducted South America Nazca Plate. Although it produced no surface damage, the event generated clear co‐seismic ionospheric disturbances (CSIDs) detectable in GNSS‐based Total Electron Content (TEC) data from the Brazilian RBMC network.
