Solar total irradiance variability measured by SOVA-2 on board EURECA
Abstract
During its 9 months of operation, the experiment SOVA-2 (Solar Constant and Variability) on board the European Retrievable Carrier (EURECA) has measured the total solar irradiance with two radiometers of the type PMO6-R. The solar variability has been investigated by bivariate spectral analysis of the irradiance and the Photometric Sunspot Index (PSI) to account for the sunspot blocking and after removal of the spot influence with the MgII-Index as proxy for the contribution of faculae and other bright magnetic elements.
