Doug,

I downloaded and tested a sample of the new data being added to the
data2/TIGGE/gepxx.tHHz.pgrb2cfFF files.

I found in addition to 2m dewpoint, that specific humidty was also
available in the file at 2m (wheras the note you have from Brent listed
only 2m dewpoint) therefore I saw 11 additional parameters and not 10.

The parameter name I use for specific humidity is SPFH. Dewpoint is
DWPK, and
potential vorticity is PVOR. The vertical coordinate for the PVOR is
320K THTA,
and the 2 meeter AGL is 2m HGHT.
