Data assimilation in the geosciences: An overview of methods, issues, and perspectives
We commonly refer to state estimation theory in geosciences as data assimilation (DA). This
term encompasses the entire sequence of operations that, starting from the observations of a …

Combining data assimilation and machine learning to infer unresolved scale parametrization
In recent years, machine learning (ML) has been proposed to devise data-driven
parametrizations of unresolved processes in dynamical numerical models. In most cases …
