Modeling of regional magnetic field applying spherical functions: practical aspect

Геофизический журнал, 2019
Modeling of geomagnetic field and creation of geomagnetic maps is one of the main directions of geomagnetic studies. For constructing global model the global spherical Lejeandre functions are used in most cases, though for constructing regional magnetic ...

A Model of the Geomagnetic Field at Epoch 1975 [PDF]

Geophysical Journal International, 1975
Summary The main magnetic field at epoch 1975 is defined by 168 spherical harmonic coefficients (those representing the internal part to degree and order 12). A further 80 coefficients (degree and order 8) define the secular variation and, in addition, 26 secular acceleration coefficients (those most significantly determined) are included.

Free core nutation: new large disturbance and connection evidence with geomagnetic jerks [PDF]

, 2015
Variations in free core nutation (FCN) are connected with various processes in the Earth's fluid core and core-mantle coupling, which are also largely responsible for the geomagnetic field variations, particularly the geomagnetic jerks (GMJs). A previous

Improved dynamic geomagnetic rigidity cutoff modeling: testing predictive accuracy [PDF]

, 2007
. In the polar atmosphere, significant chemical and ionization changes occur during solar proton events (SPE). The access of solar protons to this region is limited by the dynamically changing geomagnetic field.
