    v2 v3  
    77The routine has to be called by all processes that are model processes. A common place is to call the routine in `assimilate_pdaf` after an analysis step or in `distribute_state_pdaf`.

    9 The interface is the following:
     9The interface is:
    1010{{{
    1111  SUBROUTINE PDAF_iau_reset(type_iau, nsteps_iau, flag)
    12 }}}
    13 with the following arguments:
    14 {{{
    15     INTEGER, INTENT(in) :: type_iau     !< Type of IAU
    16                                            !< (0) no IAU
    17                                            !< (1) constant increment weight 1/nsteps_iau
    18                                            !< (2) Linear IAU weight with maximum in middle of IAU period
    19                                            !< (3) Zero weights for null mode (can be used to apply IAU on user side)
    20     INTEGER, INTENT(in) :: nsteps_iau      !< number of time steps in IAU
    21     INTEGER, INTENT(out) :: flag           !< Status flag

    2523Hints:
    2624 * It is recommended to only call this routine after or just before a forecast phase.
    27  * Calling this routine during a forecast aphse will change the IAU weights and might stop the application of IAU if `nsteps_iau` is below the number of time steps performed in the current forecast phase.
     25 * Calling this routine during a forecast phase will change the IAU weights and might stop the application of IAU if `nsteps_iau` is below the number of time steps performed in the current forecast phase.
