STEREO-B SWAVES: One-Minute Averaged Low Frequency Radio Receiver Data

STEREO-B satellite radio receiver data provides wave intensity, source direction, and angular size measurements. The data covers frequencies from 40 kHz to 16 MHz, corresponding to heliocentric distances from about 1 solar radius to 1 astronomical unit. The dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyze solar radio wave intensity based on frequency measurements from 40 kHz to 16 MHz
• Study wave source direction and angular size based on antenna system measurements
• Investigate plasma waves near the electron plasma frequency based on the 10-40 kHz receiver data
• Perform high-resolution waveform analysis based on the 50 MHz receiver and Time Domain Sampler measurements

Strengths

• Data covers a wide frequency range from 40 kHz to 16 MHz
• Includes measurements from three mutually orthogonal 6-meter monopole antennas
• Provides one-minute averaged data for temporal analysis

Limitations

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