TIMED SEE: Daily Averaged Solar Irradiance Spectra

TIMED SEE Level 3 data files contain one daily averaged solar irradiance spectrum in 1 nm intervals, extracted from satellite instrument data. The data includes 38 emission lines and diode irradiances, averaged from 14-15 measurements per day after applying corrections for atmospheric absorption and flare removal. The dataset is produced by the National Aeronautics and Space Administration.

Use Cases

• Model solar energy output based on daily averaged irradiance spectra.
• Analyze solar emission line variability based on the 38 extracted lines.
• Study atmospheric absorption effects on solar measurements based on applied corrections.
• Monitor long-term solar degradation trends based on time-averaged daily data.

Strengths

• Data provides solar irradiance spectra in 1 nm intervals, offering high spectral resolution.
• Includes 38 specific emission lines extracted from the instrument spectra.
• Daily averages are derived from 14-15 measurements per day, providing temporal consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
