TRAP: Ground-based Vector Magnetic Field Data from Trapper Creek, Alaska

Ground-based vector magnetic field measurements from the Trapper Creek station in Alaska, with a 0.5-second time resolution. The data is Level 2 processed and part of the University of Alaska network, provided by the National Aeronautics and Space Administration. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling geomagnetic field variations based on high-resolution time-series data.
• Analyzing space weather events and their ground-level magnetic signatures based on vector field measurements.
• Calibrating satellite magnetic field data using ground-based observations from a known station location.
• Studying local magnetic anomalies in the Alaska region based on data from a specific geographic station.

Strengths

• Data has a high temporal resolution of 0.5 seconds.
• Station location is precisely specified with geographic coordinates (Latitude 62.3, Longitude 209.8).
• Data is processed to Level 2, suggesting a degree of quality control.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
