The VIRGO Experiment on the ESA/NASA SOHO Mission provides continuous high-precision measurements of total solar irradiance (TSI) and spectral irradiance at 402, 500, and 862 nm. It also measures frequencies, amplitudes, and phases of solar oscillation modes in the range of 0.001 to 8 mHz. Data are available from public archives maintained by PMOD/WRC, Rutherford Appleton Laboratory, Institut d'Astrophysique Spatiale, and Osservatorio Astronomico di Torino.
Use Cases
- Modeling solar energy output based on total solar irradiance (TSI) measurements.
- Analyzing spectral solar variability based on irradiance data at 402, 500, and 862 nm.
- Studying solar oscillation modes based on frequency, amplitude, and phase data in the 0.001 to 8 mHz range.
- Calibrating satellite instruments using high-precision, high-stability solar irradiance reference data.
Strengths
- Provides continuous high-precision, high-stability, and high-accuracy measurements.
- Measures three distinct types of solar data: total irradiance, spectral irradiance at three wavelengths, and oscillation modes.
- Data is archived at multiple public institutions, suggesting redundancy and accessibility.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
Provenance
