Recently, many people have found polarisation features in the SCIAMACHY Level-1c spectrum, in the form of jumps. The jumps are found to be caused by the polarisation correction algorithm, which is evidenced by the fact that the jumps occur only when the polarisation correction is switched on, and only at cluster transitions where the integration time changes. We explain the origin of the jumps, which is the failing polarisation correction algorithm, and indicate how a change in the data processor can avoid the occurrence of these jumps even in the case of a failing polarisation correction.
