Voyager 1 PRA Highband Radio Data from Jupiter Encounter, 48-Second Resolution

Voyager 1 Planetary Radio Astronomy (PRA) highband receiver data collected during the Jupiter encounter from 1979-02-01 to 1979-04-13. The dataset provides 48-second resolution mean power measurements in millibels across 128 frequency channels from 1.2 MHz to 40.4 MHz, designed for observing Jovian decametric emissions. It was produced by the National Aeronautics and Space Administration and includes binary data files, IDL save sets, and quick-look GIF spectrogram plots for both polarization channels.

Use Cases

• Analyzing Jovian decametric radio emission patterns based on the 128-channel highband receiver data.
• Studying radio wave polarization using the provided right-hand (RH) and left-hand (LH) intensity measurements.
• Creating calibrated spectrograms of Jupiter's radio spectrum using the binary data and associated GIF plots.
• Investigating temporal variations in planetary radio power at 48-second resolution over the 1979 encounter period.

Strengths

• Data is calibrated and provided in specific physical units (millibels), with a defined zero-point reference.
• Covers a well-defined, scientifically significant time period (1979-02-01 to 1979-04-13) during the Voyager 1 Jupiter encounter.
• Includes multiple derived data products: raw binary files, IDL save sets, and quick-look GIF spectrogram plots for both polarizations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Data format is specialized (binary BIN files), requiring specific tools like IDL for full interpretation.
