Hello,<br>
<br>
I'm trying to nest into a previous generated NMM output a finer domain.
In order to do so, I'm postprocessing d01 original output with WPP,
then I obtain a GRIB file that I can use as initial and boundary
condition file for the new domain02 run. (I'm using Vtable.NAM to
ungrib that file)<br>
<br>
I'm facing some troubles with this scheme. Here it is the landmask of
my d02:<br>
<br>

<br>
I run metgrid and real_nmm.exe succesfully, but when I run wrf, after
the first iterations I obtain NaN values over the land points. This
values appear not just in the surface nor in the whole column, for
instance here it goes two plots of v-wind variable at wrfout file at
the first vertical level (upper row) and the upper vertical level
(bottom row), at the initialization time (left column) and after 3
iterations (right column):<br>

<br>
<font color="#330033">Moreover, I've observed some inconsistencies
betwen the "landsea" (from the GRIB file of the previous d01 run) and
the "landmask" (from geo_nmm of domain02) contained in met_nmm files.
In addition to some expected differences between this 2 variables, it
looks like land is displaced by some kind of spatial shift from
northwest to southeast.<br>

<font color="#330033"><br>
Does anybody have any advice on where could it be the problem of these
issues? Thanks in advance.<br>
