Voyager 1 PWS: Saturn Magnetosphere Plasma Wave Intensities, 4-Second Intervals

Voyager 1 spacecraft measured sixteen-channel electric field intensities near Saturn's magnetosphere. Each 4-second interval provides field strengths across frequencies from 10 Hz to 56.2 kHz, useful for event searches and trend analysis. The National Aeronautics and Space Administration provides this edited data with separate calibration tables for converting raw data numbers to antenna voltages.

Use Cases

• Detecting plasma wave events near Saturn based on 4-second interval electric field intensities.
• Analyzing frequency trends across 16 logarithmically spaced channels from 10 Hz to 56.2 kHz.
• Calibrating raw data numbers to electric field amplitudes using the provided calibration tables and antenna length.
• Studying the structure of Saturn's magnetosphere through in-situ wave measurements.

Strengths

• Data provides measurements across 16 distinct frequency channels for each 4-second interval.
• Includes calibration procedures and tables to convert raw data numbers to physical antenna voltages.
• Edited data is roughly proportional to the log of electric field strength for initial analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data gaps are not zero-filled or tagged, which may complicate continuous time-series analysis.
