Antarctic Geomagnetic Field Variations Recorded at Arrival Heights

A magnetometer system installed at Arrival Heights, Antarctica, records two horizontal components of Earth magnetic field variations (dB/dt). The system began continuous operation in January 1989 and is maintained by personnel from the University of Newcastle. It operates in conjunction with a network of similar Australian magnetometers.

Use Cases

• Analyze frequency of ultra low frequency geomagnetic pulsations to indicate source regions of space plasma waves.
• Study correlation between observed auroral morphology and dynamics and solar wind/interplanetary magnetic field conditions.
• Investigate magnetospheric wave-like processes corresponding to energetic processes at the solar wind/magnetosphere boundary.
• Model effects of particle precipitation on optical emissions in the lower atmosphere using correlated magnetometer and all-sky camera data.

Strengths

• Continuous year-round recording since January 1989 provides a long-term time series.
• Data collection is coordinated with a network of similar magnetometers at four other Australian Antarctic stations.

Limitations

• Specific row count, column details, and file formats are unknown.
• The dataset's geographic coverage is limited to a single high-latitude Antarctic site.
