In this project the acceleration mechanisms of the up-welling ions at source regions altitude will be investigated based on data obtained from the CHAMP (400km), GRACE (500km), and DMSP (830km) satellites. For the first time the role of the neutral particles in the thermosphere will be included in the considerations.
The Earth's magnetic field has undergone temporal and spatial
variations including polarity reversals. Global models of the Earth's magnetic field derived from geomagnetic satellite and observatory data, but also from historical and archeomagnetic data provide unique insights to the dynamical processes. Consolidated knowledge of these processes by a joint analysis of geomagnetic field observations and numerical simulation of the geodynamo can facilitate schemes to forecast Earth's magnetic field changes.
Cooperation of SANSA Space Science (South Africa) and GFZ, within the Inkaba yeAfrica project. This involved the establishment of a new geomagnetic observatory in 2006 which is operated jointly now in Keetmanshoop (Namibia) and cooperative repeat station surveys on 40 locations in South Africa, Namibia and Botswana, which will continue over several years.
