High Frequency Magnetic Field Data from Eskdalemuir Observatory, 2015

High frequency 100 Hz measurements of the Earth's magnetic field from two horizontal induction coils at the UK's Eskdalemuir Observatory. The data covers the full calendar year of 2015 and includes supporting Matlab code, calibration files, and spectrogram thumbnails. This dataset was provided by the British Geological Survey.

Use Cases

• Analyze geomagnetic disturbances and space weather events based on high-frequency magnetic field measurements.
• Develop signal processing and calibration techniques for induction coil data using the provided Matlab code and calibration files.
• Validate and benchmark geophysical models using real-world observatory data from a specific location and time period.
• Generate spectrograms for visualizing magnetic field frequency content over time.

Strengths

• Data covers a full, contiguous year from January to December 2015.
• Includes calibration files and example code for converting raw data to SI units.
• Provides supplementary metadata about the equipment and setup, and thumbnail spectrograms for initial inspection.

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.
• Data is from a single observatory location, which may reflect geographic bias.
