Geomagnetic main field modeling with DMSP [PDF]

Journal of Geophysical Research: Space Physics, 2014
AbstractThe Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar‐terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC‐C.

A statistical model of the geomagnetic field

pure and applied geophysics, 1964
A statistical model of the geomagnetic field is derived, based on the assumption of an axial geocentric dipole field of strengthHe at the equator perturbed by randomly directed components of constant magnitudeh. The model fits the dispersions found from an analysis of the 1945 field, and the ratioh/He obtained for this field and from the palaeomagnetic

A model of the geomagnetic field for 1970

Journal of Geophysical Research, 1974
A mathematical description of the geomagnetic field for 1970 has been derived by using 360,000 land, sea, and airborne measurements accumulated since 1939. The model is expressed by 168 spherical harmonic coefficients gnm, hnm to m = n = 12. It was used as the basis for the 1970 edition of the U.S. World Charts of Magnetic Variation.

A model of the geomagnetic field for 1975

Journal of Geophysical Research, 1976
A new model of the near-surface geomagnetic main field and its secular variation has been derived. The main field part, a degree 12 spherical harmonic series of 168 internal source terms, was derived from 1248 representative values having a nearly even distribution over the earth.

Correlation‐based modeling and separation of geomagnetic field components [PDF]

Journal of Geophysical Research: Solid Earth, 2016
AbstractWe introduce a technique for the modeling and separation of geomagnetic field components that is based on an analysis of their correlation structures alone. The inversion is based on a Bayesian formulation, which allows the computation of uncertainties.

Positioning of the Ionospheric Field-Aligned Irregularities With Geomagnetic Field Model

IEEE Geoscience and Remote Sensing Letters, 2020
An observation model is introduced for accurate positioning of the ionospheric field-aligned irregularities (FAIs). The model is applied to the Hainan coherent scatter phased array radar (HCOPAR) in the Hainan island of China and constructed based on the International Geomagnetic Reference Field (IGRF) model.
