    55The internal structure of PDAF is organized into a generic part providing the infrastructure to perform ensemble forecasts and filter analysis steps. The generic part is independent of the particular filter algorithm and only distinguishes between ensemble based filters (all filters except SEEK) and mode based filters (currently only SEEK). The filter-specific routines are called through an internal interface.

    7 Each filter algorithm consists of a minimum of 6 routines. All routines are called trough the internal interface of PDAF, except for the "put state" routine (`PDAF_put_state_FILTERNAME` where FILTERNAME is the name of the selected filter).

    1313The routine `PDAF_init` calls
    14  * `PDAF_init_filters` - interface routine to `PDAF_FILTERNAME_init`[[BR]]
    15    * `PDAF_FILTERNAME_init` performs the filter-specific initialization of parameters and calls the user-supplied routine that initializes the initial ensemble of model states.
    16  * `PDAF_alloc_filters` - interface routine to `PDAF_FILTERNAME_alloc`[[BR]]
    17    * `PDAF_FILTERNAME_alloc` allocates the filter-specific arrays.
    18  * `PDAF_options_filters` - interface routine to `PDAF_FILTERNAME_options`
    19    * `PDAF_FILTERNAME_options` is an optional routine. Its purpose is to display an overview of available options for the filter algorithm.
     14 * `PDAF_init_filters` - interface routine to `PDAF_X_init`[[BR]]
     15   * `PDAF_X_init` performs the filter-specific initialization of parameters and calls the user-supplied routine that initializes the initial ensemble of model states.
     16 * `PDAF_alloc_filters` - interface routine to `PDAF_X_alloc`[[BR]]
     17   * `PDAF_X_alloc` allocates the filter-specific arrays.
     18 * `PDAF_options_filters` - interface routine to `PDAF_X_options`
     19   * `PDAF_X_options` is an optional routine. Its purpose is to display an overview of available options for the filter algorithm.

    2222The routine `PDAF_get_state` calls
    23  * `PDAF_initinfo_filters` - interface routine to `PDAF_FILTERNAME_initinfo`
    24    * `PDAF_FILTERNAME_initinfo` displays information on the current configuration of the filter algorithm.
     23 * `PDAF_initinfo_filters` - interface routine to `PDAF_X_initinfo`
     24   * `PDAF_X_initinfo` displays information on the current configuration of the filter algorithm.

    27 The routine `PDAF_print_info` only includes the interface to `PDAF_FILTERNAME_memtime`
    28  * `PDAF_FILTERNAME_memtime` displays information on the execution duration of the different parts of the assimilation process as well as information on the amount of allocated memory. This functionality is optional.
     27The routine `PDAF_print_info` only includes the interface to `PDAF_X_memtime`
     28 * `PDAF_X_memtime` displays information on the execution duration of the different parts of the assimilation process as well as information on the amount of allocated memory. This functionality is optional.

    31 The routine `PDAF_put_state_FILTERNAME` is called directly from the model code. There is a separate routine for each filter. The standard implementation  calls
    32  * `PDAF_FILTERNAME_initinfo`
     31The routine `PDAF_put_state_X` is called directly from the model code. There is a separate routine for each filter. The standard implementation  calls
     32 * `PDAF_X_initinfo`
    3333   * This is the same routine that is called by `PDAF_get_state`. Here, it is only called, if the offline mode of PDAF is used.
    34  * `PDAF_FILTERNAME_update`
     34 * `PDAF_X_update`
    3535   * This routine contains the actual assimilation or analysis step of the filter algorithm.
