     3This page documents the routine `PDAFomi_obs_op_gridpoint` of PDAF-OMI.
     4
     5The routine provides an observation operator for observations that are grid point values in the state vector. It is usually called in `obs_op_OBSTYPE` in an [wiki:OMI_observation_modules OMI observation module].

     9The interface is:

     14    REAL, INTENT(in)    :: state_p(:)      ! Process-local model state provided by PDAF
     15    REAL, INTENT(inout) :: obs_f_all(:)    ! Full observed state for all observation types (array provided by PDAF)

     18'''Note:'''
     19 * The necessary index information for the observation operator was initialized in `init_obs_OBSTYPE` of the observation module.
