Abstract

Calibrated time-series data are acquired from Geoscience Australia's geomagnetic observatory network in Australia and Antarctica. Indices of geomagnetic activity are derived from these time series. 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.

Lineage

Digital geomagnetic data was first collected by GA in 1979. Before that time, Australian geomagnetic data had been collected in analog form (primarily on photographic paper), beginning with the establishment of the first geomagnetic observatory in Hobart in 1840. In some instances, pre-1979 analog records have been digitised; the earliest data in the dataset being from 1/1/1924. However, in most cases the analog records remain undigitised. Since 1979, existing observatories have been converted to digital operation and additional observatories have been added to the network. GA's geomagnetic observatory network currently stands at 10 observatories in Australia and Antarctica. Data are being added to the dataset in near real-time.
