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

STEREO-A SWAVES 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 Rs to 1 AU. The dataset includes one-minute averages from the Low Frequency Receiver (LFR) and is provided by NASA. The data was last updated on March 13, 2026.

Use Cases

• Analyze solar radio wave intensity based on the described frequency range measurements
• Study wave source direction and angular size based on the receiver capabilities
• Investigate plasma wave phenomena near the electron plasma frequency based on the 10-40 kHz receiver
• Perform high time-resolution analysis of radio emissions based on the 50 MHz receiver 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
