PALEOZONE is part of a German focussed interdisciplinary co-operation program funded by the Deutsche Forschungsgesellschaft (the German national science funding agency). The aim of the program is to investigate the phenomenon of magnetic polarity transitions co-ordinated by different communities.

|
Thus, the program comprises groups that measure the paleomagnetic field during past field reversals, groups that model the geomagnetic dynamo, and finally three groups that investigate the impact of geomagnetic reversals on the Earth system:
|
|
|
The group of Prof. Glassmeier at the University of Braunschweig models possible settings of the outer magnetic field of the Earth during a polarity transition and tracks extraterrestrial charged particles through the Earth magnetosphere into the near-Earth space;
|
|
|
The groupe of Prof. Kallenrode at the University of Osnabrück models the resulting ionisation profiles of extraterrestrical particles into the middle and lower atmosphere for the magnetic-field settings and particle tracks given by the Braunschweig group, with special emphasis given to large events like solar proton events;
|
|
|
The PALEOZONE group models the impact of different magnetic field scenarios on the composition of the middle atmosphere, using the ionisation profiles provided by the Osnabrück group.
