[Met_help] [rt.rap.ucar.edu #70046] History for the data format about the ECMWF

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

hello
     I am from Shandong Meteorological Bureau, I met a problem when I used MET to do some verification about ECMWF EPS data recently. The data from ECMWF is GRIB1 format also,but the MET did not recognize the ECMWF GRIB1, would you tell me how to handle this prolbem? I put the ECMWF data detail format in the attachment. 
I'm looking forward to your early reply.


Best regrads.

Subject: the data format about the ECMWF
From: Julie Prestopnik

Hello.

met-5.0 does not include support for the ECMWF usage of GRIB.  In
previous
versions of MET, the GRIB tables were harded-coded, but the code is
now
reading them from a flat-file at runtime.

In met-5.0, it's reading it from the installed met-5.0 directory
"share/met/table_files/nceptab_flat.txt".

In METv4.1, it's reading it from:
   METv4.1/data/table_files/nceptab_flat.txt

I would expect that MET can read ECMWF GRIB1 files, but that it just
uses
the  wrong names for the variables.

If you'd like to change MET's behavior, you could edit that flat file
to
use whichever abbreviations and units you'd like.  The next time you
run
the MET tools, it'll just read in the updated strings and use them.

It would be preferable to more full support ECMWF GRIB data without
putting
this onus on the user, but we don't currently have ready access to
ECMWF
data.  So it's difficult to support.

I hope this helps.

Julie
