GO E PWS: Galileo Plasma Waveform Measurements from Second Earth Encounter

Waveform measurements from the Galileo spacecraft's plasma wave receiver during its second Earth encounter. The data includes electric or magnetic waveforms sampled at rates of 201,600, 25,200, or 3,150 samples per second through corresponding bandpass filters. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyze plasma wave spectra and propagation based on wideband waveform measurements.
• Study electric field fluctuations in Earth's magnetosphere based on dipole antenna data.
• Investigate magnetic field variations from the search coil antenna measurements.
• Validate and calibrate plasma wave models using high-sample-rate time-series data.

Strengths

• Data originates from the Galileo spacecraft, a major NASA planetary science mission.
• Specifies three distinct high sample rates (201,600, 25,200, 3,150 s^-1) and corresponding bandpass filters (80, 10, 1 kHz).
• Includes both electric (dipole antenna) and magnetic (search coil antenna) waveform measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
