Van Allen Probes EFW Sensor Feedback Loop Model Data

A collection of model results simulating the anomalous response of the Van Allen Probes EFW instrument's sensor stub feedback loop. It includes five arrays of data, such as a 1000x20 double for gain and a 1000x20 double for phase difference, analyzed in the Greene et al., 2026 manuscript.

Use Cases

• Analyze the feedback loop gain over 20 densities and 1000 frequencies to understand sensor response characteristics.
• Study the phase difference between input and output across the modeled density and frequency ranges for system behavior validation.
• Use the complex phasor representation of the feedback response for signal processing and control system analysis.
• Examine the relationship between the modeled density range and frequency range to identify resonant conditions in the plasma environment.

Strengths

• Model outputs are defined with specific dimensions, including a 1000x20 array for gain and a 1000x20 array for phase difference.
• Data is directly linked to a peer-reviewed manuscript (Greene et al., 2026) and its Figure 5, providing academic context.
• The dataset archives fundamental modeling results for a specific instrument anomaly, offering focused research material.

Limitations

• The dataset consists solely of model-generated data, lacking corresponding observational measurements from the actual instrument for direct validation.
• Data is provided in a .mat file format, which requires specialized software like MATLAB or Python libraries for access and analysis.
• The scope is limited to the specific feedback loop anomaly, not covering broader EFW instrument or Van Allen Probes mission data.
