In this study, we take advantage of the waveform classification developed for the Envisat (CCI project) and SARAL/AltiKa missions (PEACHI project) that allows discriminating echo returns from leads in the ice pack, ice floes and open ocean. All echoes are retracked using the same adaptive algorithm. After editing and correction the measurements are used to build cycle-wise grids of sea level anomaly in the Arctic Ocean with unprecedented data availability in ice covered areas.
We present the methodology used to build this new dataset, its validation and the new insights on Arctic Ocean sea level variability that can be derived from it.
