     3This page documents the routine `PDAF3_assimilate_en3dvar_lestkf_nondiagR` which is used for the case of a non-diagonal observation error covariance matrix. The routine is part of the advanced PDAF3 interface that was introduced with PDAF V3.0.

    55The routine is typically called in `assimilate_pdaf` or directly in the model code.
    … …  
    2020 * `U_collect_state`: [[BR]]The name of the user-supplied routine that initializes a state vector from the array holding the ensemble of model states from the model fields. This is basically the inverse operation to `U_distribute_state` used in [ModifyModelforEnsembleIntegration#PDAF_get_state PDAF_get_state] and also here.
    2121 * `U_init_dim_obs_pdafomi`: [[BR]]The name of the user-supplied routine that initializes the observation information and provides the size of observation vector. This routine is part of an OMI observation module.
     22 * `U_obs_op_pdafomi`: [[BR]]The name of the user-supplied routine that acts as the observation operator on some state vector. This routine is part of an OMI observation module.
    2223 * `U_prodRinvA_pdafomi`: [[BR]]The name of the user-supplied routine that computes the product of the inverse of the observation error covariance matrix with some matrix provided to the routine by PDAF.
    23  * `U_obs_op_pdafomi`: [[BR]]The name of the user-supplied routine that acts as the observation operator on some state vector. This routine is part of an OMI observation module.
    2424 * `U_cvt_ens`: [[BR]]The name of the user-supplied routine that applies the ensemble control-vector transformation (square-root of the B-matrix) on some control vector to obtain a state vector.
    2525 * `U_cvt_adj_ens`: [[BR]]The name of the user-supplied routine that applies the adjoint ensemble control-vector transformation (with square-root of the B-matrix) on some state vector to obtain the control vector.
