High-Frequency Magnetic Field Data from Eskdalemuir Observatory, UK, 2012

Eskdalemuir Observatory in the United Kingdom provides high-frequency (100 Hz) magnetic field measurements from two horizontal induction coils. The data covers the period from September to December 2012 and includes calibration files, example Matlab code, and spectrogram thumbnails. The dataset was produced by the British Geological Survey (BGS).

Use Cases

• Analyze temporal variations in the Earth's magnetic field based on 100 Hz induction coil measurements.
• Develop or test signal calibration and processing algorithms based on the provided frequency calibration files and Matlab code examples.
• Generate spectrograms for geomagnetic activity studies based on the high-frequency time-series data.

Strengths

• Includes calibration files and example Matlab code for converting raw data to SI units.
• Covers a specific four-month period (September to December 2012) with consistent high-frequency (100 Hz) sampling.
• Provides supplementary metadata about the equipment setup and thumbnail spectrograms.

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 may reflect geographic and temporal bias inherent to a single UK observatory in late 2012.
