 **Note:**
  * 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].
+ * We recommend to use this routine only in cases where the MPI parallelization is not initialized, e.g. in separate post-analysis programs. In assimilation programs, where the parallelization is initialized for PDAF, we recommend to use the routine `PDAF_diag_rmsd` for better overall compatibility.
+ * The routine does not perform any MPI operations and can also be used if PDAF was not initialized by calling `PDAF_init`.
