Figure caption: A long-term dataset was created by combining data from GOME (1995-2003), SCIAMACHY (2003-2012), GOME-2B (2012-present), OMI (2004-present), OMPS-NM (2012-present), and TROPOMI (2018-present). The total ozone retrieval is based upon the WFDOAS V4 algorithm developed by us. The last modifications in the algorithm were the implementation of a  polarisation correction, Ring effect lookup table, and I0-corrected ozone absorption cross-sections. For GOME-2 the change  of the instrumental response function with time is accounted for.
