Webdata assimilation could provide us a better view of the ocean mixed layer. The basic concept of data assimilation is to combine real observations with numerical models. However, observations about the ocean mixed layer usually are sea surface temperature images from space. To solve the problem, some reduced order methods could be used (7).
