Geomagnetic field components X, Y, and Z measured in nanoteslas at Australian Antarctic and subantarctic stations. Data originates from observatories at Mawson and Macquarie Island, with secular variation information from Davis and Casey, and is stored by Geoscience Australia. This collection is part of the ASAC project 760.
Use Cases
- Analyze secular variation trends in the polar magnetic field using the Date and X, Y, Z component columns.
- Model the geomagnetic vector field by converting cartesian coordinates (X, Y, Z) to polar coordinates (D, F, I).
- Compare horizontal component (H) dynamics derived from X and Y measurements across different Antarctic stations.
- Study spatial differences in magnetic declination (D) and inclination (I) between subantarctic and continental Antarctic sites.
Strengths
- Data defines the complete magnetic vector field with three independent components (X, Y, Z).
- Includes measurements from multiple established observatory stations (Mawson, Macquarie Island, Davis, Casey).
Limitations
- Specific row count, temporal coverage, and update frequency are unknown.
- Sample data and file formats are unavailable for preview.
