MMS 4 Magnetic Ephemeris and Coordinates with Tsyganenko 2004 Model

Magnetospheric Multiscale 4 (MMS 4) spacecraft Level-2 science data at 30 ms Burst time resolution. The data product includes spacecraft position, velocity, attitude, magnetic ephemeris coordinates, and magnetic field measurements calculated using the Tsyganenko 2004 model for disturbed conditions. It is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling disturbed magnetospheric conditions based on the Tsyganenko 2004 magnetic field model.
• Analyzing spacecraft trajectory and magnetic field line footpoints based on position, velocity, and field line tracing variables.
• Studying magnetic activity indices and coordinate transformations based on Dst, Kp, and rotational quaternions.

Strengths

• Data is calculated using the Tsyganenko 2004 magnetic field model for disturbed magnetospheric conditions.
• Includes magnetic ephemeris coordinates, footpoint tracing, loss cone angles, and coordinate transformations into 11 systems.

Limitations

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