AB: The DIARAD radiometer is making measurements of the Total Solar Irradiance (TSI) as part of the VIRGO experiment on SOHO since 1996. We present its measurements and its in-flight ageing correction. The SOLCON radiometer has made point measurements of the TSI on the space shuttle in 1992, 1993, 1994, 1998, 2003. We use SOLCON as a reference instrument to make a composite of the TSI measurements of the radiometers ACRIM 2, SOVA 1, SOVA 2, DIARAD/VIRGO, PMO06/VIRGO. For further extension of the composite TSI in the past, a connection with the ACRIM1 measurements is needed. We investigate the possibility to use either the NIMBUS 7 or the ERBS radiometer to make this connection.
