Daily Southern Ocean Sea Level Anomaly And Geostrophic Currents from multimission altimetry, 2013-2019
This product contains Sea Level Anomaly (SLA) and geostrophic currents anomalies in the subpolar Southern Ocean, including its sea-ice covered parts, from 2013 to 2019. It has been constructed by combining observations from multiple satellites, including Cryosat-2, Sentinel-3A, and AltiKa. Along-track measurements have been processed with state-of-the-art algorithms, such as neural network waveform classification algorithm, or physical retracking for both leads and open ocean for AltiKa. Measurements are mapped daily on a 25-km grid south of 50°S. Dataset processing and description is available in Auger et al., Southern Ocean Sea Level Anomaly in the Sea-Ice Covered Sector From Multimission Satellite Observations [submitted].
