SDO/EVE: Solar Extreme Ultraviolet Irradiance Measurements from 2010

NASA's Solar Dynamics Observatory provides 4-Hz integrations of solar extreme ultraviolet irradiance data, beginning in 2010 and continuing. The Level 1 Version 8 data products are created by the Laboratory for Atmospheric and Space Physics and include updated long-term degradation corrections. This release from the Science Processing and Operations Center replaces all previous versions.

Use Cases

• Modeling solar irradiance variability based on 4-Hz measurement integrations.
• Analyzing long-term solar activity trends based on data starting from 2010.
• Studying the impact of solar EUV radiation on Earth's ionosphere based on spectral irradiance data.
• Calibrating space weather forecasting models based on updated degradation corrections.

Strengths

• Data collection began in 2010 and is ongoing, providing a long-term record.
• Includes updated long-term degradation corrections for instrument calibration.
• Produced by authoritative institutions: NASA, LASP, and the Univ. of Southern California Space Sciences Center.

Limitations

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