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].

该数据集包含2013年至2019年期间亚极地南大洋（包括其海冰覆盖区域）的海平面异常（Sea Level Anomaly, SLA）和地转流异常数据。它通过整合多颗卫星的观测数据构建而成，包括Cryosat-2、Sentinel-3A和AltiKa。沿轨测量数据采用最先进的算法处理，例如神经网络波形分类算法，以及针对AltiKa数据的冰间水道与开阔海域物理重跟踪算法。测量数据每日映射至南纬50°以南的25公里网格上。数据集的处理方法与详细描述可参见Auger等人的论文《基于多任务卫星观测的海冰覆盖区域南大洋海平面异常》[已投稿]。
