CIGO: College Ground-based Vector Magnetic Field Data

Ground-based vector magnetic field measurements from the College International Geophysical Observatory (CIGO) in Alaska. The Level 2 data has a 0.5-second time resolution and is provided by the University of Alaska network. The dataset is managed by the National Aeronautics and Space Administration.

Use Cases

• Modeling geomagnetic storms based on high-resolution vector magnetic field data.
• Analyzing local magnetic field variations based on data from a specific observatory location.
• Correlating magnetic disturbances with other geophysical events based on time-series measurements.
• Validating satellite magnetic field measurements based on ground-based observations.

Strengths

• Data has a high temporal resolution of 0.5 seconds.
• Station location is precisely specified (GEO Latitude 64.9, Longitude 212.1).
• Dataset originates from a recognized observatory network and 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.
