SESAME Fluxgate Magnetometer: Earth's Magnetic Field Components

SESAME Fluxgate Magnetometer Key Parameters contain H, D, and Z components of Earth's magnetic field, measuring variation relative to an arbitrary baseline. The data is accurate to 1nT, with 1 minute 'spot' values derived from 1Hz sampling. The dataset originates from the National Aeronautics and Space Administration and is referenced in a 1995 Space Science Reviews publication.

Use Cases

• Analyze temporal variations in Earth's magnetic field based on H, D, and Z component measurements.
• Correlate ground-based magnetic field data with satellite observations based on the SESAME experiment context.
• Validate models of geomagnetic activity using high-precision (1nT) spot measurements.
• Study magnetic field dynamics in the Antarctic region based on the experiment's geographical focus.

Strengths

• Data accuracy is specified as 1 nanotesla.
• Time resolution is defined as 1 minute 'spot' values from 1Hz sampling.
• Dataset is associated with a published scientific reference (Dudeney et al., 1995).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
