THE METHOD TO SOLVE DRIFT IN MAIN GEOMAGNETIC FIELD

Proceedings of the Mongolian Academy of Sciences, 2016
The method to solve the velocity of drift in MGF is written in this paper. This method is based on the dynamo theory for geomagnetic field. The velocity of drift in the main geomagnetic field is also solved from the condition that the power variation of ...

Oxygen Ion Percentage Inferred From the Cutoff Frequencies of Ionospheric ELF Hiss Emissions

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The lower cutoff frequency of hiss emissions observed in the ionosphere is controlled by local plasma composition and density. This study identifies 6,340 ionospheric hiss wave events based on observations from the China Seismo‐Electromagnetic Satellite (CSES‐01) from 1 August 2018 to 31 July 2020.

Statistical relationships between variations of the geomagnetic field, auroral electrojet, and geomagnetically induced currents

Solar-Terrestrial Physics, 2019
Using observations from the IMAGE magnetic observatories and the station for recording geomagnetically induced currents (GIC) in the electric transmission line in 2015, we examine relationships between geomagnetic field and GIC variations.

Magnetic Field Disturbance Induced by the Enhanced Suprathermal Ring Current in the Magnetosphere of Saturn

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.

A Compensation Method for the Geomagnetic Measurement Error of an Underwater Ship-Borne Magnetometer Based on Constrained Total Least Squares

Sensors
When magnetic matching aided navigation is applied to an underwater vehicle, the magnetometer must be installed inside the vehicle, considering the navigation safety and concealment of the underwater vehicle.

Long‐Term Trends in the Ionospheric Equivalent Slab Thickness as a Proxy of Climate Change in the Ionosphere

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Global warming warms the lower atmosphere, but cools and contracts the upper atmosphere. These changes also affect the ionosphere, altering the vertical distribution of plasma through changes in the plasma scale height. Here, we use ionospheric equivalent slab thickness (τ) multidecadal time series, derived through observations from co‐located

COMPARATIVE ANALYSIS OF GEOMAGNETIC DISTURBANCES IN THE ODESSA MAGNETIC ANOMALY AREA IN THE 24TH SOLAR ACTIVITY CYCLE

Radio Physics and Radio Astronomy, 2019
Purpose: The main oscillation periods of the geomagnetic field perturbation level in the Odesa magnetic anomaly area are studied by the data observed at the “Odesa” geomagnetic observatory within the 24th solar activity cycle.
