Polar PWI Key Parameters: Plasma Wave Observations at 5-Minute Resolution

Key parameters from the Polar Plasma Wave Instrument contain observed electron, proton, and oxygen cyclotron frequencies, plus average and peak electric and magnetic fields across 160 frequencies from two swept frequency receivers. The dataset includes spacecraft position in magnetic coordinates and time standards, with data mapped to a fixed array of approximately logarithmically spaced frequency values. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Analyzing electron, proton, and oxygen cyclotron frequency behavior based on the derived frequency variables.
• Studying the relationship between electric and magnetic field peaks and averages across 160 frequency steps.
• Correlating plasma wave activity with spacecraft position in magnetic coordinates.
• Investigating frequency mapping techniques between swept frequency receiver modes and fixed logarithmic arrays.

Strengths

• Contains data across 160 frequency values for comprehensive spectral analysis.
• Provides 5-minute temporal resolution for time-series analysis of wave phenomena.
• Includes derived key parameters (cyclotron frequencies) and raw field measurements.

Limitations

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