SDO/EVE Level 2: Solar EUV Irradiance Spectra and Lines, 2010-2018

From 2010 day 120 through 2018 day 108, this dataset provides solar extreme ultraviolet (EUV) irradiance measurements from NASA's Solar Dynamics Observatory (SDO) Extreme Ultraviolet Variability Experiment (EVE). The Level 2 products, created and maintained by the Science Processing and Operations Center (SPOC) at the Laboratory for Atmospheric and Space Physics, include merged spectra from 3.01-106.99 nm and derived line irradiances. This Version 8 release replaces all previous versions.

Use Cases

• Modeling solar spectral irradiance for atmospheric studies based on the 3.01-106.99 nm wavelength range.
• Analyzing temporal variability of specific solar emission lines based on the derived lines files.
• Cross-calibrating other solar EUV instruments based on the 1 AU-adjusted irradiances.
• Studying long-term solar activity trends based on the 8-year time series from 2010 to 2018.

Strengths

• Covers an 8-year time range from 2010 to 2018, providing a long baseline for solar cycle studies.
• Spectral data spans a broad wavelength range from 3.01 to 106.99 nm, covering key EUV emission regions.
• Irradiances are adjusted to a standard 1 AU distance, facilitating direct comparison and modeling.
• Represents a validated Version 8 release that replaces all previous versions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific ML tasks.
• The description notes fill values at the extreme ends of the spectral range where there is no detector signal.
