  Initial Request
----------------------------------------------------------------

Hi,

After debug GRIB-ECMWF table, ( many thanks) another problem appears in
using met-5,2 version.

I have a netcdf observation file provided by Climatological Department. Is
a CF file format ..

The file is attached to this message.

I can plot this file with :

plot_data_plane obs_prec.nc  obs_prec.ps 'name="TOT_PREC";level="(0,*,*)";'
 and the  obs_prec.ps looks OK.
But when I've try to run ( for COSMO model !)
:
wavelet_stat

using CONFIG file
..........................

/
// Forecast and observation fields to be verified
//
fcst = {
   field = [
      {
        name       = "TOT_PREC";
        level      =  [ "Z0" ];
        cat_thresh = [ >0.1, >=5.0 ];
      }
   ];
}

obs = {
   field = {
      name  = "TOT_PREC";
     level = "(0,*,*)";
      cat_thresh = [ >=0.1, >=5.0 ];
   };
}
// obs = fcst;
------------------

I have the error:

Dictionary::lookup_array() -> lookup failed for name "obs.field"

and if I uncomment "obs=fcst"

ERROR  : NcCfFile::data(NcVar *, const LongArray &, DataPlane &) -> needed
3 arguments for variable TOT_PREC, got 2
----------
The field TOT_PREC in obs file is TOT_PREC(time,lon,lat)... and the
forecast is TOT_PREC(lon,lat)..
..................

How can I manage this ?

Thank you in advacnce for your help,

Otilia Diaconu

Otilia,

Please look closely at how you've defined obs.field and compare it to
how
fcst.field is set.  It looks to me like you're missing square brackets
[
and ] in the obs.field section.

The field entry is an array and should be surrounded by those square
brackets.  Each array entry is a dictionary that is surround by curly
braces { and }.


obs = {
   field = [
     {
        name  = "TOT_PREC";
        level = "(0,*,*)";
        cat_thresh = [ >=0.1, >=5.0 ];
      };
   ];
}

Does that fix the problem?

John

Hi John, oh yes  !  You have pointed on the error ! the brackets fixed
the
problem ! May be I have picked one old config file ??? I can' t
explain the
missed brackets !!!
It' s ok now !
The problem is solved
Thank you
