POMME-2 Magnetic Model of the Earth

POMME is a main field model providing the geomagnetic field in the region from the Earth's surface to an altitude of a couple of thousand kilometers. POMME-2.5 includes the time varying core field, crustal field, the ring current field modulated by the Dst/Est/Ist Indices, a time averaged magnetospheric field, the penetration of the horizontal part of the Interplanetary magnetic field (IMF), and the fields induced by Earth rotation in the external fields.

A feature unique to POMME is the representation of this magnetospheric field in geocentric solar magnetospheric (GSM) coordinates. In difference from the 1.4 version the ring current correction depends on a new developed Est/Ist index. For details see the Est/Ist-index page at NOAA.
