International Geomagnetic Reference Field Revision 1987 [PDF]
Abstract The International Geomagnetic Reference Field (IGRF) is a series of mathematical models of the main geomagnetic field and its secular variation, the models consisting of sets of spherical harmonic (or Gauss) coefficients.

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

We describe the way a global model of the geomagnetic field has been built using vector field data acquired by the absolute scalar magnetometers (ASM) running in vector mode on board the Alpha and Bravo satellites of the European Space Agency (ESA) Swarm

Earth’s radiation belt and ring current are donut-shaped regions of energetic and relativistic particles, trapped by the geomagnetic field. The strengthened solar wind dynamic pressure (Pdyn) can alter the structure of the geomagnetic field, which can ...

Mapping of steady-state electric fields and convective drifts in geomagnetic fields – Part 2: The IGRF [PDF]
A method of mapping electric fields along geomagnetic field lines is applied to the IGRF (International Geomagnetic Reference Field) model. The method involves integrating additional sets of first order differential equations simultaneously with ...

Ninth generation international geomagnetic reference field released [PDF]
The coefficients for the new 9th Generation International Geomagnetic Reference Field (IGRF) were finalized at the XXIII General Assembly of the International Union of Geophysics and Geodesy (IUGG), held in Sapporo, Japan, in July 2003. The IGRF is widely used as a mathematical representation for the Earth's magnetic field in studies of the Earth's ...

Reference fields and global views: Australian and international geomagnetic reference fields [PDF]
By the mid 1960s there was general recognition of the need for an internationally accepted mathematical model of the earth's main field and its secular variation. Such a model would provide a standard for studies of magnetic anomalies, field residuals of external origin, the external form of the main field, the location of conjugate points, the long ...

Development of a Systematic Model for Study on the Phenomena of Ionospheric and Geomagnetic Variations [PDF]
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 ...

International Geomagnetic Reference Field‐2000 [PDF]
A group of geomagnetic field modellers associated with the International Association of Geomagnetism and Aeronomy (IAGA) Division V Working Group 8, periodically examines various geomagnetic field representations from which the Earth's main field and its secular variation can be computed.
