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.

Model coefficients and related (experimental) software (code for reading pomme 2.5 coefficient table, to calculate model vectors and wrapper code for Matlab and IDL). A propper documentation is still missing. Includes (with 12-Dec-2004) a little fix from Stefan Maus. Little bugfix at 18-Dec-2004.
