SNOE: Daily Solar Soft X-ray Irradiance (2-7 nm) from 1998-2000

Daily integrated values of solar soft X-ray irradiance (2-7 nm) measured by the SNOE Solar X-ray Photometer. The data cover the period from March 11, 1998 to October 1, 2000 and include irradiances measured at the spacecraft and adjusted to 1 A.U. Also included are 10.7 cm solar radio flux measurements from Ottawa and Lyman Alpha photon fluxes from the UARS SOLSTICE instrument.

Use Cases

• Modeling solar activity cycles based on daily integrated X-ray irradiance.
• Correlating solar X-ray flux with radio flux measurements from Ottawa.
• Analyzing space weather impacts based on Lyman Alpha photon flux data.
• Studying solar irradiance variations over a specific 2.5-year period.

Strengths

• Data covers a specific 2.5-year period from March 1998 to October 2000.
• Includes multiple correlated solar measurements: X-ray irradiance, radio flux, and Lyman Alpha flux.
• Irradiance values are adjusted to a standard astronomical unit (1 A.U.).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data format is listed as BIN, which may require specialized tools for access.
