Geophysics - Geomagnetics

Calibrated time-series data are acquired from Geoscience Australia's geomagnetic observatorynetwork in Australia and Antarctica. Indices of geomagnetic activity are derived from these timeseries. These primary and derived data are provided to international data centres and agencies, space weather analysts, the resource exploration sector, and research institutions. They are used in navigation, magnetic-field modelling, resource exploration and exploitation, space weather monitoring and geoscience research.
