[Wrf-users] Vtable problem with NAM 12km (6hours) during ungrib.exe and geog data

Dear WRF-USERS,

I would like to post below discussion.
Thanks for your co-operations

Hello WRF-USERS,

I am trying to WRF run with NAM 12km (6hours) data for year of 2012.
The version of current WRF and NAM data is below;

   - WRFV3.7
   - WPSV3.7
   - NAM12km 6hours data (eg.20120607.nam.t00z.awphys00.grb2.tm00)



*Question1) When I do "./ungrib.exe", I have warning massages that I have
never see during exercise case. Error messages are highlighted in red color
in below table.Would you advised me how do I resolve it? *

geoedu at geoedu-PowerEdge-T620:~/WRF/WPS$ ln -sf
ungrib/Variable_Tables/Vtable.NAM Vtable

geoedu at geoedu-PowerEdge-T620:~/WRF/WPS$ ./link_grib.csh
/home/geoedu/WRF/WPS/NAM12/2012*

geoedu at geoedu-PowerEdge-T620:~/WRF/WPS$ ./ungrib.exe

*** Starting program ungrib.exe ***

Start_date = 2012-06-07_00:00:00 , End_date = 2012-06-08_00:00:00

output format is WPS

Path to intermediate files is ./

Subsoil level 300 in the GRIB2 file, was not found in the Vtable

Subsoil level 300 in the GRIB2 file, was not found in the Vtable

Subsoil level 300 in the GRIB2 file, was not found in the Vtable

Subsoil level 300 in the GRIB2 file, was not found in the Vtable


*Question2) I'd like to run WRF in very high spatial resolution (dx/dy
<1km). As I understand, I need high geographical data (Now, I use basic
data in WRF package) for high resolution simulation. Would you comment
where can I find high resolution geog data? And how do I configure it in
WRF model?  *


Thanks for your co-operation in advance.

Yours sincerely
BongJae Kuk
