The recently updated operational level lb-2 Off-line data processor for SCIAMACHY (SGP30) contains several updates and evolutions in comparison to the former operational version. The retrieval from nadir measurements in the UV/VIS spectral region had been extended with the cloud algorithm SACURA to obtain the cloud-top height and cloud optical thickness as additional product. The retrieval of total columns for O3 and NO2 is now in-line with the scheme applied in the version 4 of the GOME data processor (GDP4). In contrast to GDP4, the cloud-top height and cloud optical thickness from SACURA are used instead of ROCINN. The presentation provides an overview about the evolution of this part of the processor and will close with an outlook to coming versions.
