    33This page documents the routine `PDAF_diag_rmsd` of PDAF, which was introduced with PDAF V3.0.

    25  * The routine is used to compute the RMSD with regard to some reference state. To compute the ensemble-sampled standard deviation, i.e. the estimated RMSD from the data assimilation, there are the routines [wiki:PDAF_diag_stddev_nompi] and [wiki:PDAF_diag_stddev].
     25 *  * The routine is used to compute the RMSD between two state vectors. To compute the ensemble-sampled standard deviation, i.e. the estimated RMSD from the data assimilation, there are the routines [wiki:PDAF_diag_stddev_nompi] and [wiki:PDAF_diag_stddev].
    2626 * The routine performs MPI operations to obtain the global result. These operations are done within the communicator `COMM_filter` which is specified as an argument. This allows to also use the routine if PDAF was not initialized by calling `PDAF_init`.
