Matematička analiza magnetskog polja zemlje / Mathematical analysis of geomagnetic field

Vojnotehnički Glasnik, 2006
Poznavanje matematičkih transformacija kojima se može predstaviti intenzitet vektora magnetskog polja Zemlje ima veoma veliki značaj. Definisanjem koeficijenata transformacionih funkcija omogućava se predstavljanje raspodele vrednosti polja na određenom ...

WHUEMM: global core field modelling from multiple satellites and comparative evaluation of inversion strategy

Earth, Planets and Space
Measurements from low Earth orbit satellites play an important role in modern geomagnetic field modelling. In this study, we present two geomagnetic field models, WHUEMM-S, derived by sequential inversion, and WHUEMM-C, derived by comprehensive inversion.

Modeling of the Sq geomagnetic field induced by tidal oscillations of the atmosphere

Earth and Planetary Physics
The Sq (solar quiet) geomagnetic field is generated by the electric currents in the E-region of the ionosphere, driven by the atmospheric tides. It is a critical part of high-precision geomagnetic field modeling.

Using neural networks to study the geomagnetic field evolution

Annals of Geophysics, 2008
study their time evolution in years. In order to find the best NN for the time predictions, we tested many different kinds of NN and different ways of their training, when the inputs and targets are long annual time series of synthetic ...

Features and Source Current of Long‐Period Induced Geoelectric Field During Magnetic Storms: A Case Study

Space Weather, 2020
We present a case study on the long‐period ( >105 s) induced geoelectric field disturbance during magnetic storms. A set of continuous 33‐day measurements of the geoelectric field, geomagnetic field, geomagnetic indices, and interplanetary magnetic field

New geomagnetic measurements in the Republic of Macedonia

Annals of Geophysics, 2013
This study presents measurements of the geomagnetic field of the Republic of Macedonia, performed through a network of newly defined repeat stations. The measurements of these elements were in the intervals of 3.378° ≤ DD ≤ 3.983°, 57.276° ≤ I ≤ 59.005°,

Fifty-year investigation of the correlation between the geomagnetic field and climate

地球与行星物理论评
After 50 years of research on the correlation between the geomagnetic field and climate, we have gained a deeper understanding that the regulation of climate by geomagnetic field changes is far more complex than previously imagined.
