The sea level of the Polar Oceans is an important climate indicator. The CryoSat-2 satellite has been measuring the polar oceans with great success, and has improved the sea level uncertainties remarkably . We present the DTU/TUM sea level record based on more tahn 15 years of ESA radar satellite altimetry data in the Arctic Ocean from the ERS2 (1995) to CryoSat-2 (present) satellites. The Arctic sea level record is part of the ESA CCI Sea level initiative and has been updated with a new and better CryoSat processing from the ESA GPOD processing. Furthermore, we present a sea level record from the Southern Ocean as part of the ESA CryoSat+ Antarctica project based on ten years of CryoSat-2 measurements. The changes in the sea level are temporal and spatial analyzed.
