An Overview of Geomagnetic Field Models

1980
Abstract : Over the last decade, the utility of geomagnetic field models or the mathematical representations of the geomagnetic field has expanded considerably, both for civilian and military applications. Such an increase has been accompanied with more interest in models and demands for better accuracies with resultant changes in techniques of model ...

A model for transition fields during geomagnetic reversals

Nature, 1988
Palaeomagnetic studies of the reversal of the geomagnetic field have produced a number of palaeomagnetic records of intermediate or transition fields during reversals. These transition fields may provide an important clue as to the nature of the geodynamo. During the last reversal, the geomagnetic field was no longer dipolar1, but the field appeared to

Mathematical Properties Relevant to Geomagnetic Field Modeling

2010
Geomagnetic field modeling consists in converting large numbers of magnetic observations into a linear combination of elementary mathematical functions that best describes those observations.The set of numerical coefficients defining this linear combination is then what one refers to as a geomagnetic field model. Such models can be used to produce maps.

A Predictive Geomagnetic Field Model for Epoch 1990.5

1990
Abstract : An epoch 1990.0 geomagnetic field model will be produced by the Naval Oceanographic Office (NAVOCEANO) using magnetic field measurements from the recently launched (April 1990) Polar Orbiting Geomagnetic Survey satellite for part of the input data.
