ULYSSES JUPITER HISCALE LEMS: Ion Counts from 1991-1992 Jupiter Encounter

HISCALE Low-Energy Magnetic Spectrometer ion counts at 120 degrees from the Ulysses spacecraft spin axis. The data covers the Jupiter encounter from 1991-12-31 to 1992-02-16, including 1-hour averaged inbound cruise data and 15-minute averaged encounter data. The dataset was produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing ion flux variations during a planetary encounter based on the specified time ranges.
• Modeling charged particle behavior in Jupiter's magnetosphere based on averaged ion count data.
• Comparing pre-encounter cruise data with high-resolution encounter data based on the described averaging intervals.

Strengths

• Data covers a specific planetary encounter event with a defined time range from 1991-12-31 to 1992-02 16.
• Includes two distinct temporal resolutions: 1-hour averaged cruise data and 15-minute averaged encounter data.
• Produced by the authoritative National Aeronautics and Space Administration.

Limitations

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