The BGS Geomagnetism team has updated its 'Model of the Earth's Magnetic Environment'
The 2008 version of MEME contains:
It reveals details of, for example:
Future versions of MEME will further improve the model of the core field, and include models of ionospheric and magnetospheric fields.
Geomagnetic field models are used in navigation, geophysical surveys, oil production and in scientific studies, ranging from the upper atmosphere to the Earth's deep interior. BGS has many years' experience in modelling the geomagnetic field on regional and global scales.
A new model of the vertical component of the lithospheric field; strongest lithospheric fields are shown in red and blue. Large continental anomalies and symmetrical features either side of the Atlantic sea-floor spreading axis are clearly visible.
