IMAGE RPI: Monthly Electron Density Values from Satellite Radio Imager

Electron density values derived from the IMAGE satellite's Radio Plasma Imager using an automated fitting program with manual correction. The data points are determined by algorithms that fit enhancements in dynamic spectra to resonance bands or continuum edges, following rules established in published research. This dataset is produced by NASA and was last updated in March 2026.

Use Cases

• Modeling ionospheric electron density based on satellite-derived resonance band measurements.
• Analyzing plasma wave propagation based on identified Upper Hybrid Resonance or Z-mode frequencies.
• Validating automated space physics algorithms based on the described rule-based fitting procedure.
• Studying magnetospheric conditions using manually corrected, algorithmically determined data points.

Strengths

• Data generation follows a documented, peer-reviewed methodology [Benson et al., GRL, 2004].
• Includes manual correction to mitigate potential errors from the automated algorithm.
• Produced by the authoritative organization NASA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data size are unknown, which may limit suitability assessment.
• The description notes the automated procedure does not guarantee data points are correct.
