Antarctic Geophysical Observatory Time Series Data

Geomagnetic and seismological observatory data from three Antarctic stations operated by Geoscience Australia. The dataset includes vector components of the Earth's magnetic field, specifically X, Y, and Z measurements in nanoteslas. This data is part of a global monitoring network.

Use Cases

• Modeling geomagnetic field variations at Mawson station using the X, Y, and Z time series.
• Analyzing correlations between seismic events and magnetic field disturbances recorded at Macquarie Island.
• Studying long-term trends in the vertical magnetic component (Z) at Casey station for climate research.
• Calibrating global geomagnetic models with ground-truth data from the Antarctic observatory network.

Strengths

• Data originates from three permanent observatories (Mawson, Macquarie Island, Casey) forming a stable network.
• Includes three independent vector components (X, Y, Z) defining the complete magnetic field.

Limitations

• Specific row count, temporal coverage, and update frequency for the dataset are unknown.
• Historical data from closed stations (Heard Island, Wilkes) may not be fully integrated or accessible.
