Hi Robert,

I don't have that file, and a quick search comes up empty...  but as a first 
stab, maybe try copying either g2varswmo2.tbl or g2varswmo3.tbl to 
g2varswmo34.tbl in the gempak/tables/grid directory and see if maybe that gets 
you somewhere? Might be a bunch of undefined or incorrectly identified 
variables, but might get you going in the right direction?

Good luck..

Pete

Subject: [gembud] Decoding ECMWF OpenData grib2 files with wgrib2/GEMPAK


Hello,



Is anyone successfully decoding OpenData ECMWF grib2 files with GEMPAK after 
converting with wgrib2?



After using wgrib2 to convert file to complex3 grib type, I gte this error when 
running dcgrib2:



[1736142] 251117/1822[GB -31]  Could not open parameter table file 
g2varswmo34.tbl



I don't see a g2varswmo34.tbl in latest GEMPAK release on Github. Anyone have a 
workaround?



Thanks,

Robert Mullenax
