[Ncep.list.emc.nmmb-questions-and-answers] t2m, rh2m, u10m, ... at t=0

[Pau]

Hi Marco,

Thanks very much for the answer, we are going to test it right now.

We should see if DFI changes our verification scores but I would expect 
it doesn't, taking into account we are not doing analysis cycling with 
NMMB.

Just a small question, apart from filter_method=3, are using the regular 
values for filtering parameters:

nsecs_bcktdfi: 3600         # HALF backward filter window (s)        (TDFI)
nsecs_fwdtdfi: 3600         # HALF forward filter window (s)         (TDFI)

?

In our case we are running with around 2.5 km horizontal resolution and 
5.625 seconds of time step. Probably we should make some tunning of this 
parameters...

Many thanks.

Pau
