     3The page document the user-supplied call-back routine `U_init_obs`.
     4
     5The routine `U_init_obs` is a call-back routine that has to be provided by the user. In the simplified interface the predefined name of the routine is init_obs_pdaf, but in the full interface, the user can choose the name of the routine.
     6The routine is used with all global filters. The routine is called during the filter analysis step. When the routine is called PDAF provides an array for the vector of observation, which needs to be filled with the observation values in this routine.
     7
     8The interface is the following:
     9{{{
     10SUBROUTINE U_init_obs(step, dim_obs_p, observation_p)
     11}}}
     12with
     13 * `step` : `integer, intent(in)`[[BR]] Current time step
     14 * `dim_obs_p` : `integer, intent(in)`[[BR]] Size of the observation vector
     15 * `observation_p` : `real, intent(out), dimension(dim_obs_p)`[[BR]] Vector of observations
     16
     17Note:
     18 * For a model using domain decomposition, `observation_p` is the vector of observations that exist on the model sub-domain for the calling process.
