v41 v42 113 113 === Defining the state vector === 114 114 115 The ensemble initialization routine is the first location at which the user has to fill a state vector (or array of state vectors). A state vector is the collection of all model sfields that are handled in the analysis step of the assimilation procedure into a single vector. Usually one concatenates the different model fields as complete fields. Thus, the vector could contain a full 3-dimensional temperature field, followed by the salinity field (in case of an ocean model), and then followed by the 3 fields of the velocity components.115 The ensemble initialization routine is the first location at which the user has to fill a state vector (or array of state vectors).

E.g. in routines that fill model fields from a state vector or in the routine providing the observation operator.
