The primary measure of the quality of sea surface temperature (SST) fields obtained from satellite-borne infrared sensors has been the bias and variance of matchups with co-located in-situ values. Because such matchups tend to be widely separated, th

Multi-modal data assimilation of sea surface currents from AIS data streams and satellite altimetry using 4DVARNet

Over the last decades, space oceanography missions, particularly altimeter missions, have greatly advanced our ability to observe sea surface dynamics. However, they still struggle to resolve spatial scales below ~ 100 km. On a global scale, sea surf

Over the core region of the Agulhas Current, new estimations of ocean surface velocities are reported using the increasing dataset from the Automatic Identification System (AIS), initially designed to monitor vessel traffic. A two‐step strategy is
