About DFI

Hi everybody,
is anyone using DFI in your models? Or is a better option discard the first 6 hours of the output and run without filtering?
Best,

Luis

Hi Luis,

I use TDFI (DFI_OPT = 3) on all my operational runs and it does a good job of removing start up artefacts.
My outer domains are 12km with 4km nests.
The "price" is only about 5 minutes added to the run times.
