    4949For the analysis step of ensemble filters several routines need to be implemented. We prove a conceptional overview here. The detailed interfaces are then described on the following pages.

    52 [[BR]]'''Figure 1:''' Required routines for the analysis step of 3D-Var methods. There are four groups of routines: The interface to the model (orange), the observation module (red), state localization in case of Ensemble or Hybrid Var using the LESTKF (purple), and handling of covariances (blue). The routine marked in yellow are additions compared to what is required for ensemble filters.

    5454Figure 1 gives an overview of the different routines that might need to be provided to the analysis step of an a 3D-Var method. The actual routines depend on the chosen 3D-Var method as wil be described after discussing the groups of subroutines.
