Voyager 2 Plasma Wave Spectrometer: Jupiter Magnetosphere Electric Field Intensities

NASA's Voyager 2 Plasma Wave Spectrometer (PWS) Version 1.1 data set provides edited, 4-second electric field intensity measurements from the vicinity of Jupiter's magnetosphere. The data consists of field strengths for sixteen logarithmically spaced frequency channels ranging from 10 Hz to 56.2 kHz. Data are uncalibrated but include separate calibration tables for converting raw data numbers to antenna voltages.

Use Cases

• Searching for plasma wave events based on raw electric field intensity data numbers.
• Performing trend analysis of wave activity across sixteen frequency channels.
• Calibrating raw data numbers to antenna voltages using the provided calibration tables.

Strengths

• Data is from the Voyager 2 mission, a primary source for Jupiter magnetosphere observations.
• Provides measurements across sixteen distinct frequency channels, from 10 Hz to 56.2 kHz.
• Includes a separate calibration table (SA_CL_4S.TAB) for converting raw data numbers to voltages.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data gaps are not zero-filled or tagged, and missing channels within a scan are zero-filled.
