Geoscience Data Journal, Volume 13, Issue 3, July 2026.ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.

An Information Geometry‐Based Method to Study Atmospheric and Seismic Phenomena With VLF Signals
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract We propose to employ the framework of information geometry to detect anomalies in Very Low Frequency (VLF) and Low Frequency (LF) signal propagation, measured globally across amplitude and phase channels. Using a sliding‐window approach, the probability distributions of signal data are compared over adjacent intervals, defining a statistical ...

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Auroral transport models (ATMs) play an important role in quantitative studies of optical auroras, their driving mechanisms, and their effects on the ionosphere and thermosphere. TREx‐ATM was initially developed as the support model for the Transition Region Explorer (TREx) mission, and has gained increasing applications in the community in ...

Performance Investigation of Four Ionospheric Models in Estimating hmF2 in High‐Latitude Regions
Space Weather, Volume 24, Issue 7, July 2026.Abstract As a critical parameter characterizing the vertical structure of the ionosphere, the peak height of the F2 layer (hmF2) plays an essential role in frequency selection and signal propagation in high‐frequency (HF) communication systems. Accurate prediction of hmF2 is particularly important in high‐latitude regions.

Wavelet analysis of geomagnetic jerks
, 2013 Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Journal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

A coordinated ground-based and IMAGE satellite study of quiet-time plasmaspheric density profiles [PDF]
, 2003 Cold plasma mass density profiles in the plasmasphere have been determined for the geomagnetically quiet day of 19th August 2000 using the cross-phase technique applied to ground-based magnetometer data from the SAMNET, IMAGE and BGS magnetometer arrays.
