Ulysses SCE C1: Solar Corona Radio Ranging Data, August–September 1991

Differential range delay and total electron content measurements from the Ulysses Solar Corona Experiment during its first solar conjunction. The data were collected at ten-minute intervals between August 7 and September 5, 1991, via the NASA Deep Space Network. The processed data are provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling solar corona plasma density based on differential range delay measurements.
• Analyzing temporal variations in total electron content (TEC) during a solar conjunction.
• Studying the dispersive effects of ionized media on dual-frequency radio signals.
• Calibrating radio-sounding techniques for future deep-space missions.

Strengths

• Data covers a specific solar conjunction event (C1) from August 7 to September 5, 1991.
• Measurements are recorded at a high temporal resolution of ten-minute intervals.
• Includes both differential range delay and calculated total electron content (TEC) parameters.
• Accuracy of the range delay measurement is specified as approximately 50 range units.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data file format is BIN, which may require specialized tools for access.
