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

STEREO-A SWAVES provides one-minute averages of low frequency radio receiver data. The receivers measure wave intensity, source direction, and angular size in frequencies from 40 kHz to 16 MHz, corresponding to heliocentric distances from about 1 solar radius to 1 AU. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyze solar radio wave intensity based on the described frequency range measurements
• Study the direction and angular size of heliocentric radio sources based on the receiver capabilities
• Model plasma wave behavior near the electron plasma frequency based on the 10-40 kHz receiver data
• Perform high-resolution temporal analysis of radio events based on the 50 MHz receiver measurements
• Investigate wideband waveform measurements on electric components based on the Time Domain Sampler description

Strengths

• Data covers a wide frequency range from 40 kHz to 16 MHz
• Includes measurements of wave intensity, source direction, and angular size
• Provides high time resolution measurements at 50 MHz
• Utilizes 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
• Data is stored in BIN format, which may require specialized tools for access
