Induction magnetometer data records two horizontal components of Earth's magnetic field variations (dB/dt) at Arrival Heights, Antarctica. The system continuously recorded hydromagnetic and ion cyclotron waves from January 1989 onward. The dataset was collected by SCIOPS in conjunction with an Australian magnetometer network.
Use Cases
- Analyze frequency of ultra-low frequency waves to identify source regions in the magnetosphere.
- Correlate magnetic field disturbance amplitudes (dB/dt) with solar wind activity to study space weather events.
- Compare North-South and East-West component time-series data to characterize wave propagation modes.
- Use long-term recordings to investigate seasonal or solar cycle variations in polar cap geomagnetic activity.
Strengths
- Continuous year-round recording since January 1989 provides a long-term time-series.
- Data is calibrated and maintained annually, ensuring measurement consistency.
- Operates in conjunction with a network of similar stations for comparative analysis.
Limitations
- Specific row count, sampling rate, and data completeness metrics are unknown.
- Data is from a single geographic location (Arrival Heights), limiting spatial analysis.
- The description indicates potential data gaps or changes due to equipment relocation in 2007.
