Subject: [gembud] C009 added to parameter name in .gem files
When decoding some ECMWF grib files using dcgrib2, it's adding "C009"
after the parameter name. For example, TMPK becomes TMPKC009. I can
rename them back to what they should be using gddiag, but I was
wondering if it's some field in the grib message that can be fixed
using grib_set prior to running it through dcgrib2.
