John, et al

I used the example grib file that was send to test the decoders packeage,
the bugs were  very apparent.  The bugs were fixed and I also update the
gribdump program to use the -g flag ( user params table ) and updated the
gribtonc and gribdump  man pages.  The table file that was sent had a
error, the name of  a NetCDF variable name cannot start with a digit, so I
created another one. ie,


       Grib;netCDF;long name               ;units;comments
       167 ;T_2meter     ;2 metre temperature     ;K    ;
       228 ;precep_total ;Total precipitation     ;m    ;

The ecmf.tbl and eecmf.cdl file are included as attachments.

There is a new decoders release with the fixes: decoders-2.4.3.tar.Z

Subject: GRIB to netCDF

Hi Russ..

It seems I have a flood of questions after years of silence...

Thanks for your prompt reply on Monday.  I got the SST data I needed
via a direct compile and execution of a little program via gcc, but I
still have not gotten the library to work in Code Warrior.  I sent a
message to Metrowerks...we'll see if I get an answer.

New problem: We are encountering difficulties in trying to convert
ECMWF GRIB files of  ensemble seasonal forecasts to netCDF.   The
issue seems to turn on the fact that the  Unidata gribtocdl utilities
are using the NCEP GRIB
parameter tables and that there are differences with ECMWF.

Any information or assistance would be greatly appreciated.

Please REPLY to ALL since Ben Hauger above is actually doing the work.

Again, many thanks, John
