Recovering external contribution from the monthly mean series of a given geomagnetic observatory

open access: yesAnnals of Geophysics, 2016
The differences between monthly mean values of the observed geomagnetic field and monthly values predicted by different models of the internal geomagnetic field (named “model biases”) for the time period 2000-2015 at several geomagnetic observatories are

South Atlantic Anomaly Areal Extent as a Possible Indicator of Geomagnetic Jerks in the Satellite Era

open access: yesFrontiers in Earth Science, 2021
Geomagnetic jerks are sudden changes in the geomagnetic field secular variation related to changes in outer core flow patterns. Finding geophysical phenomena related to geomagnetic jerks provides a vital contribution to better understand the geomagnetic ...

Introduction to Geomagnetic Fields [PDF]

open access: yesEos, Transactions American Geophysical Union, 2003
Introduction to Geomagnetic Fields is a textbook for advanced undergraduate and graduate students of geophysics. It explains the natural magnetic fields in and surrounding the Earth that arise from a variety of electric currents. The author clearly presents these different components of the Earth's magnetic field with a minimum of mathematical ...

Spremembe v gostoti energije magnetnega polja Zemlje na observatoriju PIA, Slovenija, med geomagnetno nevihto G5 11. maja 2024 (= Changes in the energy density of the Earth's magnetic field at the PIA, Slovenia, observatory during the G5 Geomagnetic Storm on May 11, 2024)

open access: yesGeodetski Vestnik
Geomagnetic storms are the largest disturbance in the Earth's magnetic field. On May 11, 2024, a geomagnetic storm occurred at the peak of the 25th solar cycle, reaching the highest level (G5) on the planetary scale.

Change of earth environment due to the decreasing geomagnetic field -The necessity of observation in Brazilian geomagnetic anomaly region-

open access: yesAntarctic Record, 1996
According to recent research on rock magnetism, the geomagnetic field intensity of our planet has been monotonically decreasing for one thousand years and it will disappear after another 1000years if the present decreasing rate continues.

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]

open access: yes, 2007
International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).
