A complex study was performed of the disturbances in geophysics parameters that were observed during a short-term period of earthquake preparation. On 4 March 2024, an M6.1 earthquake (N 42.93, E 76.966) occurred with the epicenter 12.2 km apart from the

Modeling the topside ionosphere by means of electron density values as recorded by the Swarm constellation [PDF]
The topside part of the ionosphere lies above the ionospheric F2 layer peak and extends up to the plasmasphere. Since it contains a considerable part of the ionospheric plasma, its modeling is important for telecommunication’s purposes.

Coupling of the solar wind, magnetosphere and ionosphere by MHD waves
The solar wind, magnetosphere and ionosphere are coupled by magnetohydrodynamic waves, and this gives rise to new and often unexpected behaviours that cannot be produced by a single, isolated part of the system.

IntroductionWe quantify temporal variations of geoid heights (ΔN) across Kazakhstan during 2019–2024 using satellite gravimetry, and relate these changes to recent extreme hydrological and seismic events.MethodsMonthly ΔN fields were derived from GRACE ...

Dependence of the open-closed field line boundary in Saturn's ionosphere on both the IMF and solar wind dynamic pressure : comparison with the UV auroral oval observed by the HST [PDF]
We model the open magnetic field region in Saturn's southern polar ionosphere during two compression regions observed by the Cassini spacecraft upstream of Saturn in January 2004, and compare these with the auroral ovals observed simultaneously in ...

Improved Ionospheric Correction for Dual Frequency and Differential GPS Positioning Methods [PDF]
A new three dimensional (3-D) electron density model has been developed that can give a very accurate description of the real ionospheric variation; latitudinally,longitudinally and altitudinally.
