init_obsvars_pdaf
The page documents the user-supplied call-back routine init_obsvars_pdaf
, which was introduced with PDAF V3.0.
The routine init_obsvars_pdaf
(named U_init_obsvars
inside PDAF) is a call-back routine that has to be provided by the user.
The routine is used only with the ENSRF/EAKF. The routine is called by PDAF during the analysis step and has to provide the filter with a vector of observation error variances.
The interface is:
SUBROUTINE init_obsvars_pdaf(step, dim_obs_f, var_f) INTEGER, INTENT(in) :: step ! Current time step INTEGER, INTENT(in) :: dim_obs_f ! Dimension of full observation vector REAL, INTENT(out) :: var_f(dim_obs_f) ! vector of observation error variances
The variance vector var_f
is for the full observation vector.
