ocr: VIRGO VIRGO Variability of solar Rradiance and Gravity Oscillations) determines the characteristics of acoustic and internal gravity oscil- lations by observing irradiances and radiance variations, measures the solar total and spectral irradiance to quantify their variability over periods of days to the duration of the mission. The VIRGO experiment will provide the tollowing observational and derived data: continuous high-precision, high-stability and high-accuracy measurements of the solar total and spectral irradiance and spectral radiance variation; continuous measurements of the solar pola ...
