SDO/EVE Level 3: Daily Solar Extreme Ultraviolet Irradiance Averages from 2010

Daily averaged solar extreme ultraviolet irradiance data beginning on April 30, 2010 (day 120). The data is produced by the Laboratory for Atmospheric and Space Physics for NASA's Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment. This version includes updated long-term degradation corrections and calibration based on sounding rocket measurements.

Use Cases

• Modeling long-term solar irradiance trends based on daily averaged EUV measurements.
• Analyzing solar variability for space weather forecasting based on the instrument's spectral data.
• Calibrating other solar observation instruments using the updated degradation corrections mentioned in the description.
• Studying the solar cycle's impact on the Earth's upper atmosphere based on the time-series of EUV flux.

Strengths

• Data originates from NASA's Solar Dynamics Observatory, a flagship mission.
• Includes updated calibrations based on SDO EVE sounding rocket measurements.
• Provides a long-term time series starting from a specific date (2010-04 30).

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, and HTML, which may require specialized tools for analysis.
