Welcome to the VIRGO home page

Variability of solar IRradiance and Gravity Oscillations

The Solar Monitor Experiment on-board the SOHO spacecraft

VIRGO is an international collaboration of different European countries. This is a part of the payload of the SOHO spacecraft. SOHO is an international collaboration programme between ESA and NASA. If you want learn more about this programme, you can look at the SOHO home page. If you want to learn more about VIRGO you can look at the items below. Some of which are an extract of the science book of VIRGO (the so-called Purple Book):

The scientific objectives of VIRGO are achieved using these two means:

Helioseismology and,
Radiometry?

Instruments

DIARAD
LOI
PMO6
SPM

Overview of the existing data sets

Total irradiance
Spectral irradiance
12-pixel radiance

Data Reduction Methods and Software
Theory developments hoped for
Interfacing with other Experiments
