Determination of the Radius of the Ring Current in the Earth’s Core According to the Data of the INTERMAGNET Network Observatories

Applied Sciences
The geomagnetic dynamo is currently considered the most likely source of the Earth’s main dipole field. However, the radius of the current ring located in the Earth’s core is not reliably known.

Long-Term Changes and Trends in the F2 Layer Critical Frequency over Alma-Ata (Kazakhstan)

Atmosphere
The long-term variability and trends in the F2 layer critical frequency variations over Alma-Ata [43.25 N, 77.92 E] for the period 07.1957–04.2018 are studied using near-midday, near-midnight, and hourly median foF2 values.

Quiet time F2-layer disturbances: seasonal variations of the occurrence in the daytime sector [PDF]

Annales Geophysicae, 2009
Earlier revealed seasonal/latitudinal variations of the occurrence for positive and negative F2-layer Q-disturbances have been interpreted in the framework of the present-day concept of the thermosphere-ionosphere interaction. The basic process is the

Airborne Ground Penetrating Radar, Field Test

Remote Sensing, 2021
Deployment of a ground penetrating radar (GPR) on a flying machine allows one to substantially extend the application area of this geophysical method and to simplify carrying out large surveys of dangerous and hard-to-reach terrain, where usual ground ...

The domination of Saturn’s low-latitude ionosphere by ring ‘rain’ [PDF]

Nature, 2013
Saturn’s ionosphere is produced when the otherwise neutral atmosphere is exposed to a flow of energetic charged particles or solar radiation. At low latitudes the solar radiation should result in a weak planet-wide glow in the infrared, corresponding to ...

Development of a Long Short-Term Memory (LSTM)-Based Statistical Model for Earthquake Forecasting in Central Asia

IEEE Access
Earthquake forecasting using traditional methods remains a complex task due to the inherent nonlinearity and stochastic nature of seismic activity. Therefore, this study examines the application of deep learning methods, particularly a hybrid model ...

Influence of the hypermagnetic field noise on the baryon asymmetry generation in the symmetric phase of the early universe

European Physical Journal C: Particles and Fields, 2021
We study a matter turbulence caused by strong random hypermagnetic fields (HMFs) that influence the baryon asymmetry evolution due to the Abelian anomalies in the symmetric phase in the early Universe.
