Description:

The development of efficient computational algorithms for solving data assimilation and inverse problems in geophysical hydrodynamics is one of the most important contemporary computational and informational problems. This minisymposium aims to provide an international basis to exchange the latest research achievements in the theory and applications of the inverse and data assimilation problems in geophysical hydrodynamics.We invite experts and young researches working in these fields to discuss new theoretical results, numerics of ill-posed problems for complicated mathematical models and applications.
