STEREO-A SWAVES: Solar Radio Wave Intensity and Direction Measurements

One-minute resolution time domain sampler data from the STEREO-A spacecraft, measuring radio wave intensity, source direction, and angular size. The data is collected by the National Aeronautics and Space Administration using three orthogonal 6-meter monopole antennas, covering frequencies from 40 kHz to 16 MHz and up to 50 MHz. Waveform measurements are captured at 250,000 samples per second on three electric components.

Use Cases

• Modeling solar radio burst propagation based on wideband waveform measurements.
• Analyzing plasma wave activity near 1 AU based on the 10-40 kHz receiver data.
• Correlating radio source direction with solar events based on directional measurements.
• Studying wave intensity variations across heliocentric distances from 1 Rs to 1 AU.

Strengths

• High temporal resolution measurements at 250,000 samples per second.
• Covers a wide frequency range from 40 kHz to 16 MHz, corresponding to distances from 1 solar radius to 1 AU.
• Includes simultaneous measurements on three electric components for directional 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, requiring specialized tools for access and analysis.
