 Note:
  * Using `PDAF_get_memberid` is obviously only useful if more than one ensemble member is integrated by a model task. If there are as many model tasks as ensemble members, `memberid` is always 1. In this case one can use `task_id` from the module `mod_parallel` to distinguish the ensemble members.

+Note:
+ * The routine an be useful if the observation operator does not actually operate on the state vector that is provided when [wiki:obs_obs_pdaf] is called. Their might be cases in which one likes to read model state information from a file (e.g. if the observation operator performs an averaging over time, while the state vector for the analysis step only contains a single time instance).
