THEMIS-E: Satellite Magnetic Field Measurements at 1/8 to 1/8192 Second Resolution

THEMIS-E satellite search coil magnetometer data captures magnetic field waveforms at three distinct time resolutions. The dataset includes FAST SURVEY data at 1/8 second, PARTICLE BURST data at 1/128 second, and high-resolution WAVE BURST data at 1/8192 second. This data was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing high-frequency plasma waves in Earth's magnetosphere based on the 1/8192 second WAVE BURST data.
• Studying particle acceleration events based on the 1/128 second PARTICLE BURST waveform data.
• Monitoring background magnetic field variations based on the 1/8 second FAST SURVEY data.
• Investigating wave-particle interactions by correlating waveform data with spectral products mentioned in the description.

Strengths

• Provides three distinct data products with time resolutions ranging from 1/8 to 1/8192 seconds.
• Includes specialized burst data for capturing transient events like particle and wave bursts.
• Sensor and electronics design was provided by specialized institutions LPP, Roux and Le Contel.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The PARTICLE BURST and WAVE BURST data consist of only short bursts, not continuous coverage.
