Voyager 1 PRA: Jupiter Radio Wave Spectrum with 48-Second Intervals

Voyager 1's Planetary Radio Astronomy instrument recorded radio wave spectra near Jupiter from 1979-01-06 to 1979-04-13. The dataset contains resampled summary browse data for 70 frequency channels from 1.2 kHz to 1326 kHz, with values for left and right circular polarization binned into 48-second intervals. Data were calibrated and processed by the instrument team, with missing records omitted and bad data indicated by a zero value.

Use Cases

• Analyzing temporal variations in Jupiter's radio emissions based on the 48-second interval time series.
• Studying polarization characteristics of planetary radio waves based on separate left and right circular polarization values.
• Modeling radio wave spectra across the 70 frequency channels from 1.2 kHz to 1326 kHz.
• Investigating data gaps and instrument performance during the Jupiter flyby based on the absence of zero-filled records.

Strengths

• Data covers a specific 98-day period during the Voyager 1 Jupiter encounter, from 1979-01 06 to 1979-04-13.
• Provides calibrated measurements across 70 instrument channels in uniform 19.2 kHz steps.
• Includes separate data for Left Hand Circular (LHC) and Right Hand Circular (RHC) polarization components.

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.
