Conventional altimetry from ERS-1/ERS-2 and ENVISAT provides LRM altimetry in the Arctic Ocean since 1991 which have enabled us to derive a continuous record within the ESA sea level CCI initiative for 20 years up to latitude 82. With the launch of SAR altimery onboard Cryosat-2 and with the availability of SARAL/ALtiKA Ka band altimetry two new sensors providing accurate the sea level mapping in the Arctic Ocean has been available since 2010. Extending the sea level time series derived with LRM
