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

STEREO-B satellite radio receivers measure wave intensity, source direction, and angular size in the frequency range 40 kHz to 16 MHz, corresponding to heliocentric distances from about 1 solar radius to 1 astronomical unit. The data includes measurements from a 10-40 kHz receiver for radio and plasma waves near the electron plasma frequency and high-resolution measurements at 50 MHz. National Aeronautics and Space Administration provides this dataset, last updated on March 13, 2026.

Use Cases

• Analyze solar radio wave intensity based on the low frequency receiver measurements
• Study plasma wave dynamics near 1 AU based on the 10-40 kHz receiver data
• Investigate wave source direction and angular size based on the multi-component antenna system
• Perform time-series analysis of radio emissions based on the one-minute averaged data

Strengths

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

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 a BIN format, which may require specialized tools for access
