[GEMPAK #RGI-969779]: Gempak Decoders

Hi Flavio,

Sorry I did not get back to you sooner, yesterday we had a national holiday.  I 
do not know why the link did not work for you, I tested a file upload myself at 
http://motherlode.ucar.edu/repository/alias/gempakuploads/ and it went through 
okay.  Can you not connect to that URL at all, or are you seeing the error 
after uploading?

What I meant about the grib tables is, the decoder is looking for files named 
"wmogrib203.tbl" and "wmogrib201.tbl", which do not exist.    In the past, I 
have been able to simply copy (or sym link) another file in $GEMTBL/grid/, such 
as 

cd $GEMTBL/grid/
ln -s wmogrib131.tbl wmogrib203.tbl

then the file will look like:

lrwxrwxrwx  1 gempak ustaff       12 2013-12-11 13:48 wmogrib203.tbl -> 
wmogrib131.tbl

and are available for dcgrib2 to find.  However, if the grids you are trying to 
decode have non-standard parameters, the data may not be decoded correctly with 
a "default" table.
