SOHO/Variability of Solar Irradiance and Gravity Oscillations (VIRGO) Data Archive

The VIRGO Experiment on the ESA/NASA SOHO Mission has three types of instruments to measure total solar irradiance (TSI) with the absolute radiometers DIARAD and PMO6V, spectral solar irradiance at 402, 500 and 862 nm with a 3-channel sun photometer (SPM) and spectral radiance at 500 nm with a luminosity oscillation imager (LOI). VIRGO provides - continuous high-precision, high-stability and high-accuracy measurements of the solar total and spectral irradiance and spectral radiance variation; - frequencies, amplitudes and phases of oscillation modes in the frequency range of 0.001 to 8 mHz. All SOHO/VIRGO data are available from the public SOHO data archive: http://www.pmodwrc.ch/pmod.php?topic=tsi/virgo/proj_space_virgo#VIRGO_Radiometry Mirror archives are available at: SOHO Archive at Rutherford Appleton Laboratory, UK.: http://trace.solararchive.rl.ac.uk/soho/ SOHO Archive at the Institut d'Astrophysique Spatiale, France: http://idc-medoc.ias.u-psud.fr/ SOHO Archive at Osservatorio Astronomico di Torino, Torino, Italy: http://www.oato.inaf.it/
