     3This page documents the routine `PDAF_get_localfilter` of PDAF.
     4
     5The routine returns the information whether the chosen filter is a domain-localized filter (LESTKF, LETKF, LSEIK, LNETF). It can be called in assimilate_pdaf.F90 and the return value can be used to call either PDAFomi_assimilate_global or PDAFomi_assimilate_local (or PDAFomi_put_state_global or PDAFomi_put_state_local). The value is initialized after calling PDAF_init.

     7The routine is typically called in the model code in assimilate_pdaf.

     9The interface is the following:
     10{{{
     11  SUBROUTINE PDAF_get_localfilter(lflag)
     12}}}
     13with the following argument:
     14 * `lflag`: On output the integer index is[[br]]
     15   (1) for local filters,[[br]]
     16   (0) for global filters (including LEnKF, which performs covariance localization)
