5 | 5 | This routine provides the optional functionality to prescribe the assimilation increment of each element of the local state vector a different weight. This can be used, e.g. to implement a vertical localization in the case that the local state vector is a full vertical column of the model grid. In this case, one can make the increment weight depending on the height (or depth) of a grid point. Another application is to implement weakly-coupled assimilation in which the local state vector contains all variables, but only a subset of them is updated. This is achieved by givening those element that should not be updated the weight 0. |
