THEMIS-A: Search Coil Magnetometer Waveform Data at Multiple Resolutions

THEMIS-A satellite search coil magnetometer measurements of magnetic fields in space. The dataset includes three primary data products: FAST SURVEY at 1/8 second resolution, PARTICLE BURST at 1/128 second resolution, and WAVE BURST at 1/8192 second resolution. Data was provided by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Analyze wave-particle interactions based on the high-resolution PARTICLE BURST and WAVE BURST waveform data.
• Study magnetospheric wave phenomena based on the multi-resolution FAST SURVEY, PARTICLE BURST, and WAVE BURST data streams.
• Process compressed FFT spectra for frequency analysis based on the described Particle Burst Spectra (ffp) and Wave Burst Spectra (ffw) products.

Strengths

• Provides three distinct time resolutions: 1/8s, 1/128s, and 1/8192s, enabling analysis at different scales.
• Includes multiple data products like waveform data and compressed FFT spectra, as described in the telemetry modes.
• Data originates from the authoritative source National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Some data products like PARTICLE BURST and WAVE BURST are described as 'only short bursts of data', indicating intermittent coverage.
