Voyager 2 Plasma Wave Electric Field Measurements, 1977-2013

Voyager 2 spacecraft electric field spectrum analyzer data collected from launch in 1977 through 2013, covering its journey from Earth to beyond 100 AU. The dataset includes average and peak wave electric field intensities accumulated over one-hour intervals across sixteen spectrum analyzer channels. NASA produced this dataset, which encompasses observations from cruise phases and planetary encounters with Jupiter, Saturn, Uranus, and Neptune.

Use Cases

• Analyzing plasma wave intensity variations based on one-hour averaged electric field measurements
• Studying heliospheric radio events based on the onset dates of major LF events provided in the timeline
• Investigating bow shock crossings at planetary encounters based on the event dates for Jupiter, Saturn, Uranus, and Neptune
• Tracking changes in plasma wave spectra based on data from sixteen spectrum analyzer channels

Strengths

• Data spans over 36 years from spacecraft launch in 1977 through 2013
• Includes a detailed timeline of key mission events from launch to reaching 100 AU
• Covers planetary encounters with Jupiter, Saturn, Uranus, and Neptune

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
