SAC-C Mag-F: High Precision Magnetic Scalar Data

1 second measurements of the scalar magnetic field collected by the Compact Spherical Coil Fluxgate Vector Magnetometer on the SAC-C spacecraft. The dataset is provided by the National Aeronautics and Space Administration. It was last updated on March 13, 2026.

Use Cases

• Analyze temporal variations in Earth's magnetic field based on 1-second scalar measurements.
• Validate and calibrate magnetic field models based on high-precision satellite data.
• Study geomagnetic disturbances and events based on continuous spacecraft monitoring.

Strengths

• Data is collected at a high temporal resolution of 1 second.
• Data originates from a scientific instrument on a dedicated spacecraft.
• The dataset is provided by the authoritative organization NASA.

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.
