Voyager 2 PWS: Saturn Magnetosphere Plasma Wave Intensities, 4-Second Intervals

Edited electric field intensity measurements from the Voyager 2 Plasma Wave Spectrometer's sixteen-channel analyzer during the Saturn flyby. The data consists of 4-second interval scans across logarithmically spaced frequencies from 10 Hz to 56.2 kHz. This dataset was produced by the National Aeronautics and Space Administration and is associated with a last update timestamp of 2026-03-13.

Use Cases

• Event searches for plasma wave activity based on the sixteen-channel spectrum analyzer intensities.
• Trend analysis of wave electric field strength in the vicinity of Saturn's magnetosphere.
• Calibration of raw data numbers to antenna voltages using the provided calibration tables.
• Conversion of calibrated voltages to wave electric field amplitudes for physical analysis.

Strengths

• Provides data across sixteen logarithmically spaced frequency channels, covering 10 Hz to 56.2 kHz.
• Includes a dedicated calibration table (SA_CL.TAB) to convert raw data numbers to calibrated voltages.
• Data is edited for missing channels within a scan, which are zero-filled for consistency.

Limitations

• Data gaps where complete 4-second spectra are missing are not zero-filled or tagged, requiring careful handling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
