Voyager 2: Jupiter Plasma Wave Spectra at 48-Second Intervals

From February 28 to March 22, 1979, this dataset contains calibrated electric field intensity measurements from the Voyager 2 Plasma Wave Spectrometer near Jupiter. It provides geometric averages for 16 logarithmically spaced frequency channels, ranging from 10 Hz to 56.2 kHz, stored in volts per meter. The data was processed by NASA and is at processing level 4.

Use Cases

• Analyzing plasma wave frequency spectra within Jupiter's magnetosphere based on the 16-channel spectrum analyzer data.
• Studying temporal variations in electric field intensity based on the 48-second sampling intervals.
• Modeling the noise environment of spacecraft based on the documented noise level parameter.
• Investigating data gaps and instrument performance based on the description of untagged missing intervals.

Strengths

• Data covers a specific, well-documented mission phase from 1979-02-28 to 1979-03-22.
• Provides calibrated measurements across 16 distinct frequency channels with a known noise level of 0.000005.
• Dataset is versioned (1.1) with documented upgrades for PDS compliance.

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 present and are not zero-filled or tagged, which may complicate continuous time-series analysis.
