I am having difficulty finding some good documentation regarding GDGRIB2.
Specifically, the G2TBLS, G2IS, G2IDS, G2PDT, and G2DRT sections. The method to
my madness here relates to the fact that our television graphics system will
only recognize a few PDTs, the most common being 4.0. Since not all datasets
use this template, I have had to use wgrib2 to manually change the PDT of a
given dataset, and then call the variable I am working with something other
than what it is. Sounds a little unorthodox, but as long as I know what the
variable name is referring to, everything is fine. So, to have any chance of
showing some of the more elaborate ensemble data on the air, I really need to
understand the syntax behind these 5 entries. Thanks for any help anyone can
provide.
