The International Geomagnetic Reference Field [PDF]
, 2011 The International Geomagnetic Reference Field (IGRF) is an internationally agreed and widely used mathematical model of the Earth’s magnetic field of internal origin. We describe its inception in the 1960s and how it has developed since. We also describe

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 ...

MagNet—A Data‐Science Competition to Predict Disturbance Storm‐Time Index (Dst) From Solar Wind Data
Space Weather, 2023 Enhanced interaction between solar‐wind and Earth's magnetosphere can cause space weather and geomagnetic storms that have the potential to damage critical technologies, such as magnetic navigation, radio communications, and power grids.

Universe, 2021 Magnetic fields in the inner magnetosphere can be obtained as vector sums of the Earth’s own internal magnetic field and magnetic fields stemming from currents flowing in the space plasma. While the Earth’s internal magnetic field is accurately described

Modelling the geomagnetic field.
Journal of geomagnetism and geoelectricity, 1990 Spherical harmonic models of the main geomagnetic field and its secular variation are used by navigators, exploration geophysicists, drillers of oil wells and by scientists studying the Earth's interior, its ionosphere and magnetosphere. The data on which such models are based must be of the highest quality and must be distributed as homogeneously as ...

Wavelet analysis of geomagnetic jerks [PDF]
, 2013 Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

A global climatological model of extreme geomagnetic field fluctuations [PDF]
Journal of Space Weather and Space Climate, 2020 This paper presents a multi-parameter global statistical model of extreme horizontal geomagnetic field fluctuations (dBH/dt), which are a useful input to models assessing the risk of geomagnetically induced currents in ground infrastructure. Generalised Pareto (GP) distributions were fitted to 1-min measurements of |dBH/dt| from 125 magnetometers (with

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

The CHAOS-4 geomagnetic field model [PDF]
Geophysical Journal International, 2014 We present CHAOS-4, a new version in the CHAOS model series, which aims to describe the Earth's magnetic field with high spatial and temporal resolution. Terms up to spherical degree of at least n = 85 for the lithospheric field, and up to n = 16 for the time-varying core field are robustly determined.More than 14 yr of data from the satellites Ørsted,

Development of a Systematic Model for Study on the Phenomena of Ionospheric and Geomagnetic Variations [PDF]
Journal of Astronomy and Space Sciences, 1999 Solar activities ejecting high energy particles influence satellites and satellite communications as well as perturb geomagnetic fields. To understand space environments near the Earth being influenced by the Sun, we must study about the magnetosphere ...
