PDAFomi_set_debug_flag
This page documents the routine PDAFomi_set_debug_flag
of PDAF.
The routine activates the debugging output of PDAF-OMI. It can be called, e.g. in init_dim_obs_pdafomi
to activate the debugging output for the whole analysis, or in init_dim_obs_l_pdafomi
to activate debugging output for a single local analysis domain of a domain-localized filter (i.e. LESTKF/LETKF/LNETF/LSEIK).
Detailed information on how to use and interpret the debugging output is provided on the documention of the PDAF-OMI debugging information. |
The interface is:
SUBROUTINE PDAFomi_set_debug_flag(debugval) INTEGER, INTENT(in) :: debugval ! Value for debugging flag ! (0): deactivate debug output ! (>0): activate debug output
Notes:
- The routine is provied through the module 'PDAFomi'. Thus one has to use-include the routine by
USE PDAFomi, only: PDAFomi_set_debug_flag
- For the localized filters, we recommend to activate the debugging only for single local analysis domain. Thus one can select some value of
domain_p
, e.g. ininit_dim_obs_l_pdafomi
and then callPDAFomiset_debug_flag
usingdebugval=domain_p
- The debug output is active until one calls
PDAFomi_set_debug_flag(0)
. - With parallelization one can active the debug output for a single MPI task
- The debug output writes out the complete list of obervation (e.g. for a local analysis domain). As such, it can be useful to reduce the number of assimilated observations during the debugging to shorten the outputs
