VG2-J-PRA-3-RDR-LOWBAND-6SEC-V1.0: Voyager 2 Jupiter Radio Astronomy Low-Frequency Data

VG2-J-PRA-3-RDR-LOWBAND-6SEC-V1.0 contains calibrated radio wave data from the Voyager 2 Planetary Radio Astronomy instrument during its Jupiter encounter. The dataset covers the full encounter phase from 1979-04 25 to 1979-08-04 at a 6-second resolution, measuring left and right circular power across 70 low-frequency channels. It was produced by the National Aeronautics and Space Administration and is provided in ASCII format.

Use Cases

• Analyzing Jupiter's radio emission spectrum based on the 70 low-frequency channels from 1.2 kHz to 1326.0 kHz.
• Studying temporal variations in radio power based on the 6-second sweep cycle and eight sweeps per 48-second major frame.
• Investigating polarization of radio waves based on alternating measurements of Left Hand Circular and Right Hand Circular power.
• Calibrating or validating models of planetary radio phenomena using the calibrated millibel units and defined noise floor.

Strengths

• Data covers the entire Jupiter encounter phase from 1979-04-25 to 1979-08-04, extending beyond the standard mission boundary.
• Provides high time resolution data with a 6-second sweep cycle through the receiver bands.
• Data is calibrated and provided in defined units of millibels, with a stated minimum noise floor of 2300-2400 millibels.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
