[Wrf-users] metegrid generates data at only one level by using RUC data

[Feng Liu]

Hi,
I try to use RUC data for initialization, and I am sure I have had
  ln -sf ungrib/Variable_Tables/Vtable.RUCb Vtable
  cd ./metgrid ; ln -sf METGRID.TBL.ARW.ruc METGRID.TBL

geogrid.exe, ungrib.exe and metgrid.exe work successfully.  But metgrid.exe gave me only one level of output, num_metgrid_levels was missed, please see ncdump -h  met_em.d01.2008-03-12_17:00:00.nc as shown below

netcdf met_em.d01.2008-03-12_17:00:00 {
dimensions:
        Time = UNLIMITED ; // (1 currently)
        DateStrLen = 19 ;
        west_east = 63 ;
        south_north = 48 ;
        south_north_stag = 49 ;
        west_east_stag = 64 ;
        z-dimension0012 = 12 ;
        z-dimension0016 = 16 ;
        z-dimension0024 = 24 ;

There is no any problem when I use NAM (ds609.2 data) and get right metgrid.exe runs as follow
 netcdf met_em.d01.2008-03-12_17:00:00 {
dimensions:
        Time = UNLIMITED ; // (1 currently)
        DateStrLen = 19 ;
        west_east = 63 ;
        south_north = 48 ;
        num_metgrid_levels = 27 ;
        num_st_layers = 4 ;
        num_sm_layers = 4 ;
        south_north_stag = 49 ;
        west_east_stag = 64 ;
        z-dimension0012 = 12 ;
        z-dimension0016 = 16 ;
        z-dimension0024 = 24 ;

I have no idea to fix this issue, thanks for your help  in advance.

Feng
