[GEMPAK #XCU-941477]: GDGRIB

Kimberly,

The first question I have to ask is if you have added an entry for this "TFP" 
parameter in ncepgrib129.tbl?  

Do you see any GDGRIB errors reported such as:

[GDGRIB -83]  Cannot find parameter in tables

Lastly, it would help if you could upload the .gem file you're using to the 
RAMADDA repository located at

http://motherlode.ucar.edu/repository/alias/gempakuploads/

that way I can play around with GDGRIB on my end and see what I can find.

Best,

Michael James

> I am having an issue with gdgrib writing out an empty grib file. I've

> reason, though, gdgrib just does not work for this parameter (my program
