Launched in 2010, CryoSat was designed to measurechanges in polar sea ice thickness and ice sheetelevation. To reach this goal the CryoSat data productshave to meet the highest performance standards and aresubjected to a continual cycle of improvement achievedthrough upgrades to the Instrument Processing Facilities(IPFs). Following the switch to the Baseline-C Ice IPFsthere are already planned evolutions for the nextprocessing Baseline, based on recommendations fromthe Scientific Community, Expert Support Laboratory(ESL), Quality Control (QC) Centres and Validationcampaigns. Some of the proposed evolutions, to bediscussed with the scientific community, include theactivation of freeboard computation in SARin mode, thepotential operation of SARin mode over flat-to-slopetransitory land ice areas, further tuning of the land iceretracker, the switch to NetCDF format and theresolution of anomalies arising in Baseline-C. Thispaper describes some of the anomalies known to affectBaseline-C in addition to potential evolutions that areplanned and foreseen for Baseline-D.
