[GEMPAK #TAG-149000]: CFS v2 Grib Files
- Subject: [GEMPAK #TAG-149000]: CFS v2 Grib Files
- Date: Wed, 15 May 2013 08:59:01 -0600
Hi Allan,
this is likely a grib table issue, which may be solved with the newest GEMPAK
tables from NCEP. I am working on updating the tables for the UPC GEMPAK
release, but it is not done just yet. I will write back when it is complete
and I'll be sure to test the CFS files. I am on PTO after today so will not
have a lot of time to devote to work, but may steal away for a morning session
or two so I can keep up on tickets like this one.
