Short summary
One of the main limitations for long-term space-based measurements is instrument degradation. We present an optimisation of the degradation correction approach (Krijger et al. 2014) for SCIAMACHY on-board Envisat, focusing on the improvement of the solar spectral irradiance data. The main achievement of this study is the successful integration of SCIAMACHY’s internal white light source (WLS) into the existing degradation model and the characterisation of WLS ageing in space.
