Voyager 2 PRA: Neptune Radio Wave Spectrum at 48-Second Intervals

70 instrument channels from 1.2 kHz to 1326 kHz provide radio wave flux measurements near Neptune. The National Aeronautics and Space Administration processed this data from the Voyager 2 Planetary Radio Astronomy instrument for the period from 1989 day 000 to 1989 day 365. Each 48-second interval includes separate values for left-hand and right-hand circular polarization.

Use Cases

• Analyzing temporal variations in Neptune's radio emissions based on 48-second binned time intervals.
• Studying the spectral power distribution across 70 contiguous frequency channels from 1.2 kHz to 1326 kHz.
• Comparing left-hand and right-hand circular polarization components of received radio waves.
• Investigating data gaps and calibration methods for historical space instrument data.

Strengths

• Data covers a full year of observations from 1989:000:00:00 through 1989:23:59:59.
• Provides calibrated measurements across 70 frequency channels in uniform 19.2 kHz steps.
• Includes explicit handling for bad data, indicated by a value of zero which cannot otherwise occur.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• During data gaps, entire records are absent and not zero-filled, which may complicate time-series analysis.
