SDO/EVE: Solar Extreme Ultraviolet Model Spectra at 1-Minute Cadence

NASA's Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment provides Level 4 model spectra. The data consists of 1,440 spectra per UTC day, derived from ESP quadrant diode irradiance and GOES X-ray channel ratios. The Laboratory for Atmospheric and Space Physics in Boulder, Colorado created these files, which model quiet sun, active region, and flare spectrum contributions.

Use Cases

• Model solar irradiance variability based on 1-minute cadence spectra
• Analyze flare spectrum contributions based on the described model components
• Compare solar activity models with analogous TIMED-SEE and SORCE XPS products
• Study active region evolution based on derived isothermal plasma temperature

Strengths

• Model spectra are produced at a 1-minute cadence
• Each daily product contains 1,440 spectra
• Derived from specific ESP quadrant diode and GOES X-ray channel measurements

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• File formats include BIN, PDF, HTML, which may require specialized tools
