Voyager 1 Jupiter Magnetic Field Data in System III Coordinates, 9.6 s Averages

Voyager 1's Low Field Magnetometer captured calibrated magnetic field measurements in nanoteslas during its Jupiter encounter. The data, resampled to a 9.6-second rate from original 0.06-second samples, covers the period from the inbound solar wind past the final outbound bowshock crossing. This Version 1.1 dataset from NASA's PDS archive includes added data columns and updated time formats compared to its predecessor.

Use Cases

• Modeling Jupiter's magnetospheric structure based on calibrated magnetic field vectors.
• Analyzing magnetic field fluctuations near planetary bowshocks using the 9.6-second time-series data.
• Studying instrument performance and quantization uncertainty across eight dynamic ranges.
• Comparing interplanetary magnetic field conditions in the solar wind versus within a planetary magnetosphere.

Strengths

• Data is calibrated, with quantization uncertainty precisely defined for eight instrument dynamic ranges (e.g., ±0.0022 nT for Range 1).
• Provides full coverage of the Jupiter encounter from inbound solar wind to outbound bowshock.
• Version 1.1 includes additional data columns and upgraded PDS labels compared to the previous release.

Limitations

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