South Pole geomagnetic field variations recorded by a fluxgate magnetometer. The instrument measures fluctuations from 0.03 nT to over 1000 nT, with a sampling rate of 1 Hz and a Nyquist frequency of 0.5 Hz. The data was collected by SCIOPS and last updated in September 2008.
Use Cases
- Analyze magnetic storm perturbations based on the description of fluctuations up to 1000 nT.
- Study slow terrestrial magnetic field variations based on the DC to 0.5 Hz frequency range.
- Validate magnetometer sensor performance based on the described three-coil fluxgate design.
- Model baseline geomagnetic activity based on the high sensitivity to 0.03 nT fluctuations.
Strengths
- High sensitivity capable of measuring fluctuations as small as 0.03 nT.
- Sampling rate of 1 Hz provides detailed temporal resolution for slow variations.
- Sensor design comprises three mutually perpendicular coils for multi-axis measurement.
Limitations
- Last updated 2008-09-26 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
