STEREO-B SWAVES: High-Frequency Radio Wave Data from a Solar Orbiter

STEREO-B satellite radio receivers measure wave intensity, source direction, and angular size across frequencies from 40 kHz to 16 MHz, corresponding to heliocentric distances from about 1 solar radius to 1 astronomical unit. The data includes high time-resolution measurements at 50 MHz and wideband waveform measurements from three electric components. This dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing solar radio burst characteristics based on wave intensity and frequency data.
• Studying the propagation of radio waves through the solar wind based on source direction measurements.
• Investigating plasma wave phenomena near 1 AU based on the 10-40 kHz receiver data.
• Correlating wideband waveform measurements from three electric components for multi-dimensional plasma analysis.

Strengths

• Data covers a wide frequency range from 40 kHz to 16 MHz.
• Includes high time-resolution measurements at a specific 50 MHz frequency.
• Measurements are made using three mutually orthogonal 6-meter monopole antennas.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Data is provided in a BIN file format, which may require specialized tools for access.
