Anchorage (HLMS): High-Latitude Vector Magnetic Field Data

High-latitude ground-based vector magnetic field measurements collected at 0.5-second intervals. The data is Level 2 processed and originates from the Anchorage (HLMS) station in Alaska, part of the University of Alaska network. The dataset is authored by the National Aeronautics and Space Administration and was last updated on March 13, 2026.

Use Cases

• Analyze geomagnetic disturbances based on high-latitude vector magnetic field measurements.
• Model ionospheric current systems based on ground-based magnetic field data.
• Validate satellite-based magnetic field observations based on ground station data.
• Study temporal variations in Earth's magnetic field based on 0.5-second time resolution.

Strengths

• Data has a high temporal resolution of 0.5 seconds.
• Station location is precisely specified at GEO Latitude 61.2, Longitude 210.1.
• Data is Level 2 processed, suggesting quality control.

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.
