Voyager 1 PWS: Jupiter Magnetosphere Plasma Wave Spectra, 4-Second Intervals

Voyager 1's Plasma Wave Spectrometer (PWS) recorded electric field intensities in sixteen logarithmically spaced frequency channels from 10 Hz to 56.2 kHz during its Jupiter encounter. The dataset contains edited, uncalibrated 4-second interval measurements, with gaps not zero-filled, provided by NASA. Calibration tables are included to convert raw data numbers to antenna voltages for scientific analysis.

Use Cases

• Event searches for plasma wave activity based on the sixteen-channel spectrum analyzer data.
• Trend analysis of electric field strength in the Jovian magnetosphere using the 4-second interval time series.
• Calibration of raw PWS data numbers to physical voltages using the provided lookup tables.
• Studying the frequency structure of plasma waves from 10 Hz to 56.2 kHz.

Strengths

• Data covers sixteen logarithmically spaced frequency channels from 10 Hz to 56.2 kHz.
• Includes calibration tables to convert raw data numbers (0-255) to antenna voltages for each channel.
• Time intervals are precisely associated with the beginning of each 4-second scan.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are edited but not calibrated in the primary files, requiring use of separate calibration procedures.
