Galileo PWS: 1-Minute Plasma Wave Spectra from Jupiter Orbital Mission

The Galileo orbital mission period (prime, GEM, and GMM) provides the temporal coverage for this dataset. It contains 1-minute averages of electric and magnetic wave spectra from the Galileo spacecraft's plasma wave receiver at Jupiter. The data is produced by NASA from the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer components.

Use Cases

• Analyzing plasma wave spectral density variations based on the 49-channel electric field and 34-channel magnetic field spectra.
• Studying the relationship between electric and magnetic field components in Jupiter's magnetosphere based on the provided spectral densities.
• Creating browse-level visualizations of wave activity over the mission timeline based on the reduced spectral resolution data.
• Correlating wave events with other mission data based on the 1-minute averaged time series.

Strengths

• Data covers the full Jupiter orbital mission period, including prime, GEM, and GMM phases.
• Spectral information is binned into 49 logarithmically-spaced electric channels (6 Hz to 5.6 MHz) and 34 magnetic channels (6 Hz to 75 kHz).
• Derived from three instrument sources: High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The spectral resolution is reduced for browse purposes and does not correspond to the instrument's 158 specific channels.
