The new operational level 1b-2 Off-line data processor for SCIAMACHY contains several updates and evolutions in comparison to the former operational version. The retrieval from nadir measurements 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. In contrast to GDP, the cloud-top height and cloud optical thickness from SACURA are used instead of ROCINN. In addition, the retrieval of O3 and NO2 profiles from limb measurements is now based on the retrieval package DRACULA. The presentation provides an overview about the evolution of the processor and will close with an outlook to coming versions.
