Antarctic Search Coil Magnetometer Data for Geospace Analysis

Magnetometer data from a network of five autonomous observatories in Antarctica investigates geospace electrodynamics. The PENGUIn team at Augsburg College analyzes ULF waves using search coil magnetometers deployed across the auroral zone to the polar cap. Data acquisition is supported by Iridium satellite transmission for real-time geophysical measurements.

Use Cases

• Analyze ULF wave signatures from search coil magnetometer time-series data to study dayside wave-particle interactions.
• Investigate global geomagnetic substorm signatures by correlating data from five AGOs spanning the auroral zone to the polar cap.
• Study magnetic reconnection events in the southern cusp region using high-latitude magnetometer measurements.
• Observe polar cap phenomena and neutral atmosphere dynamics through continuous, real-time geophysical data streams.
• Measure total electron content in the ionosphere using complementary GPS-based receiver data.

Strengths

• Data from five distributed autonomous observatories provides spatial coverage from the auroral zone to deep polar cap.
• Real-time data transmission via Iridium satellites ensures reliable data availability for analysis.
• Multi-instrument data acquisition enriches investigations with complementary measurements from ground and space.

Limitations

• Specific row count, column details, and temporal coverage of the dataset are unknown.
• Geographic coverage is limited to specific high-latitude Antarctic sites, introducing regional bias.
• Data freshness and update frequency are not specified.
