[Wrf-users] Re: wrfprep.pl and NNRP

[Don Morton]

Hi Ricardo,

I'm afraid I can't add much, and what I can add comes from my
somewhat feeble memory (I sent an email to someone in
Colorado a couple of weeks ago with more specifics, but can't
find the email now).  The major thing that I do remember is that
Oriol had suggested putting both the surface and analysis NNRP
files in the same directory when degribbing, but that caused problems
for me that didn't really show up until I was running real.exe.  The
problems seemed related to the LSM, and I kind of wonder if
those are the same sorts of problems you're running into.

At any rate, the one major thing I did different (with respect to Oriol's
advice) is that I put my NNRP surface files in one directory, my
NNRP analysis (3D) files in a separate directory, then degribbed them
separately.  I'm guessing that when I failed to do this, the degribbing
routines were taking the wrong fields out of the wrong files.  I've learned
that grib_prep.pl is VERY sensitive to having exactly the needed files in
a directory all by themselves - even putting a subdirectory in amongst
your needed files can sometimes cause issues.

I can send you copies of my grib_prep.nl, Vtables, wrfrsi.nl, etc. later on
if you want, but I'm hoping your problem is as simple as the one I describe
above.

Cheers,

Don
