Voyager 1 Jupiter Magnetic Field Measurements in System III Coordinates

Voyager 1's Low Field Magnetometer captured calibrated magnetic field data during its Jupiter encounter, with measurements resampled to a 1.92-second interval. The data are provided in System III (1965) coordinates and cover the period from the inbound solar wind through the last outbound bowshock crossing. This Version 1.1 dataset from NASA includes added data columns and upgraded labels compared to the previous version.

Use Cases

• Model Jupiter's magnetospheric structure based on calibrated magnetic field vectors.
• Analyze solar wind interaction with Jupiter's bow shock using time-series magnetic field data.
• Study magnetic field fluctuations near Jupiter using the 1.92-second averaged measurements.
• Calibrate or validate magnetometer models using the documented dynamic ranges and quantization uncertainties.

Strengths

• Data is calibrated, with a detailed description of the calibration process referenced.
• Specifies eight instrument dynamic ranges with precise quantization uncertainties (e.g., ±0.0022 nT for Range 1).
• Time format and data flags were modified and labels upgraded to PDS Version 3.2 for Version 1.1.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The full 60 ms instrument sampling rate data is not included; this is a 1.92-second resampled summary.
