Advancements of the Operational Level 0 to 1 Processing of SCIAMACHY

In this paper, we present an overview of the most notable changes to the operational Level 0 to 1 processing, since software version 4 of December 2002, presented at the first ACVE meeting. This paper deals only with the algorithmic developments of the processing. Not discussed are advancements in other fields which contribute to the Level 1 data quality, e.g. advancements in performance of the Ground Segment, or advancements in the quality of the on-ground calibration data (Calibration Keydata) which are provided externally to the processor. We further present an outlook to the changes in the prototype software, which are expected to become operational in the near futur
