JUNO FGM: Juno Spacecraft Fluxgate Magnetometer Calibrated Cruise Data

Juno FGM calibrated cruise observations measure the magnetic field vector using two miniature ring-core fluxgate sensors. The data set is produced by the National Aeronautics and Space Administration and was last updated in April 2026. Multiple data products accommodate different coordinate systems for the three-component vector field measurements.

Use Cases

• Modeling the interplanetary magnetic field during Juno's cruise phase based on calibrated vector measurements.
• Comparing magnetic field data in different coordinate systems based on the multiple available data products.
• Analyzing time-series trends in magnetic field components from fluxgate sensor observations.

Strengths

• Data is calibrated, which suggests a processed, analysis-ready state.
• Produced by the authoritative source National Aeronautics and Space Administration.
• Last updated metadata indicates ongoing curation as of April 2026.

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.
