Launched in 2010, CryoSat was designed to measure changes in polar sea ice thickness and ice sheet elevation. To reach this goal the CryoSat data products have to meet the highest performance standards and are subjected to a continual cycle of improvement achieved through upgrades to the Instrument Processing Facilities (IPFs). Following the switch to the Baseline-C Ice IPFs there are already planned evolutions for the next processing Baseline, based on recommendations from the Scientific Community, Expert Support Laboratory (ESL), Quality Control (QC) Centres and Validation campaigns. Some of the proposed evolutions, to be discussed with the scientific community, include the activation of freeboard computation in SARin mode, the potential operation of SARin mode over flat-to-slope transitory land ice areas, further tuning of the land ice retracker, the switch to NetCDF format and the resolution of anomalies arising in Baseline-C. This paper describes some of the anomalies known to affect Baseline-C in addition to potential evolutions that are planned and foreseen for Baseline-D.
