v8 v9 183 183 * For a model with domaindecomposition one might use the mean variance for the model subdomain of the calling process. Alternatively one can compute a mean variance for the full model domain using MPI communication (e.g. the function `MPI_allreduce`). 184 184 * The observation vector `obs_p` is provided to the rotine for the case that the observation error variance is relative to the value of the observations. 185 186 187 == Execution order of usersupplied routines == 188 189 For the SEIK filter, the usersupplied routines are essentially executed in the order they are listed in the interface to `PDAF_put_state_seik`. The order can be important as some routines can perform preparatory work for later routines. For example, `U_init_dim_obs` can prepare an index array that provides the information for executing the observation operator in `PDAF_obs_obs`. 190 191
