SESAME: Ionospheric Plasma Frequency Parameters from Antarctic Ground Stations

Three key ionospheric parameters derived from quarter-hourly ionograms by the SESAME ground-based experiment. The parameters include the lowest and highest plasma frequencies from the E-region and the highest plasma frequency from the F-region, measured in MHz. The dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling ionospheric layer behavior based on quarter-hourly plasma frequency measurements
• Correlating satellite experiment data with ground-based Antarctic measurements based on the SESAME experiment framework
• Analyzing temporal variations in E-region and F-region plasma frequencies
• Validating HF radar and ionospheric sounder models based on referenced technical methodologies

Strengths

• Parameters are derived from quarter-hourly ionograms, suggesting a high temporal resolution
• Dataset is associated with a specific scientific experiment (SESAME) and referenced technical reports
• Produced by the National Aeronautics and Space Administration

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
