PSP SWEAP SPAN-A Proton Differential Energy Flux Measurements

NASA Parker Solar Probe SWEAP instrument measurements of differential proton energy flux at each deflector step, energy, and anode. The data is provided as Level 2 (L2) files with a 7-second cadence. Users must adhere to the mission's 'Rules of the Road' for data use and publication.

Use Cases

• Model solar wind behavior based on differential proton energy flux measurements.
• Correlate proton flux variations with solar activity based on time-series data.
• Validate plasma instrument models based on multi-dimensional deflector step and anode data.
• Study particle distribution functions based on differential energy flux across measured channels.

Strengths

• Data originates from the NASA Parker Solar Probe mission, a primary source for solar wind observations.
• Provides measurements at a specific 7-second time resolution.
• Includes flux data across multiple instrument parameters: deflector steps, energies, and anodes.

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.
