Antarctic magnetic data measures plasmaspheric mass loading on magnetic field lines. The British Antarctic Survey operates a Low Power Magnetometer network with permanent and temporary sites. Data collection began in 2001.
Use Cases
- Analyzing temporal variations in magnetic field strength from 1-second resolution fluxgate measurements.
- Correlating GPS-derived position and time data with magnetic field vectors to study spatial patterns.
- Modeling plasmaspheric mass loading by examining high-resolution (1 nT) magnetic flux data.
- Investigating seasonal power constraints by comparing 1-second sampling in summer to 1-minute sampling in winter.
Strengths
- Data collected at high temporal resolution, up to 1 second.
- Magnetic field measurements have a sensitivity of 1 nT.
- Network includes both permanent and temporary sites for spatial coverage.
Limitations
- Sample rate decreases to once per minute during low-power winter conditions, reducing temporal resolution.
- Specific row count, total size, and complete geographic coordinates are unknown.
- Data freshness and last update date are unspecified.
