STEREO-B SWAVES: One-Minute Radio Wave Intensity Measurements

STEREO-B SWAVES data includes radio wave intensity, source direction, and angular size measurements from 40 kHz to 16 MHz, corresponding to heliocentric distances from about 1 Rs to 1 AU. The dataset is produced by the National Aeronautics and Space Administration and was last updated on March 13, 2026. It includes high-resolution waveform measurements from three electric components at 250,000 samples per second.

Use Cases

• Analyzing radio wave intensity fluctuations based on the 40 kHz to 16 MHz frequency range measurements.
• Determining source direction and angular size of heliospheric radio emissions.
• Studying plasma waves near the electron plasma frequency based on the 10-40 kHz receiver data.
• Examining wideband waveform characteristics based on the 250,000 samples/second measurements from three electric components.

Strengths

• Measures wave intensity, source direction, and angular size across a wide frequency range from 40 kHz to 16 MHz.
• Includes high time resolution measurements at 50 MHz and waveform measurements at 250,000 samples/second.
• Data collection uses three mutually orthogonal 6-meter monopole antenna systems.

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.
