    v13 v14  
    8585Without further settings, the localization radius is set to 0 so that only
    8686the observed grid points are changed by the assimilation.
    87 You can further set the localization radius with
    88 {{{
    89 ./PDAF_offline -filtertype 7 -local_range 5
     87You can further set the localization cut-offg radius with
     88{{{
     89./PDAF_offline -filtertype 7 -cradius 5
    9090}}}
    9191Now the LESTKF is used with a localization radius of 5 grid points. This
     
    9595use
    9696{{{
    97 ./PDAF_offline -filtertype 7 -local_range 5 -locweight 2
     97./PDAF_offline -filtertype 7 -cradius 5 -locweight 2
    9898}}}
    9999Now, the filter is applied with the 5th-order polynomial function by
     
    201201To change the ensemble size to 6 states, you can use for example
    202202{{{
    203 mpirun -np 6 ./model_pdaf -dim_ens 6 -filtertype 7 -local_range 3
     203mpirun -np 6 ./model_pdaf -dim_ens 6 -filtertype 7 -cradius 3
    204204}}}
    205205which chooses to run the LESTKF with a localization radius of 3 grid points.
