Implementations of a square-root ensemble analysis and a hybrid localisation into the POD-based ensemble 4DVar

The main purpose of this study is to propose a hybrid localisation technique for the proper orthogonal decomposition (POD)-based ensemble 4-D variational assimilation (PODEn4DVar) method with the aim of facilitating its implementation. This hybrid localisation scheme takes full advantages of both th...
