STEREO-A SWAVES: High Frequency Receiver Data in One Minute Averages

The STEREO-A spacecraft's SWAVES instrument measures 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. National Aeronautics and Space Administration provides this data, which includes high-resolution measurements at 50 MHz and wideband waveform captures from three electric components via three orthogonal 6-meter monopole antennas. The dataset was last updated on March 13, 2026.

Use Cases

• Analyze solar radio wave intensity patterns based on the 40 kHz to 16 MHz frequency range data.
• Study wave source direction and angular size for heliocentric distances from 1 Rs to 1 AU.
• Investigate plasma wave phenomena near the 1 AU electron plasma frequency using the 10-40 kHz receiver data.
• Perform high time-resolution analysis of radio emissions based on the 50 MHz receiver measurements.
• Conduct waveform analysis on three electric components using the Time Domain Sampler wideband data.

Strengths

• Data covers a wide frequency range from 40 kHz to 16 MHz, enabling multi-scale analysis.
• Includes high time-resolution measurements at a specific 50 MHz frequency.
• Utilizes three mutually orthogonal 6-meter monopole antennas for multi-component electric field capture.

Limitations

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